How to Write a Conclusion for Research Papers (with Examples)

How to Write a Conclusion for Research Papers (with Examples)

The conclusion of a research paper is a crucial section that plays a significant role in the overall impact and effectiveness of your research paper. However, this is also the section that typically receives less attention compared to the introduction and the body of the paper. The conclusion serves to provide a concise summary of the key findings, their significance, their implications, and a sense of closure to the study. Discussing how can the findings be applied in real-world scenarios or inform policy, practice, or decision-making is especially valuable to practitioners and policymakers. The research paper conclusion also provides researchers with clear insights and valuable information for their own work, which they can then build on and contribute to the advancement of knowledge in the field.

The research paper conclusion should explain the significance of your findings within the broader context of your field. It restates how your results contribute to the existing body of knowledge and whether they confirm or challenge existing theories or hypotheses. Also, by identifying unanswered questions or areas requiring further investigation, your awareness of the broader research landscape can be demonstrated.

Remember to tailor the research paper conclusion to the specific needs and interests of your intended audience, which may include researchers, practitioners, policymakers, or a combination of these.

A conclusion in a research paper is the final section where you summarize and wrap up your research, presenting the key findings and insights derived from your study. The research paper conclusion is not the place to introduce new information or data that was not discussed in the main body of the paper. When working on how to conclude a research paper, remember to stick to summarizing and interpreting existing content. The research paper conclusion serves the following purposes: 1

  • Warn readers of the possible consequences of not attending to the problem.
  • Recommend specific course(s) of action.
  • Restate key ideas to drive home the ultimate point of your research paper.
  • Provide a “take-home” message that you want the readers to remember about your study.

Types of conclusions for research papers

In research papers, the conclusion provides closure to the reader. The type of research paper conclusion you choose depends on the nature of your study, your goals, and your target audience. I provide you with three common types of conclusions:

A summarizing conclusion is the most common type of conclusion in research papers. It involves summarizing the main points, reiterating the research question, and restating the significance of the findings. This common type of research paper conclusion is used across different disciplines.

An editorial conclusion is less common but can be used in research papers that are focused on proposing or advocating for a particular viewpoint or policy. It involves presenting a strong editorial or opinion based on the research findings and offering recommendations or calls to action.

An externalizing conclusion is a type of conclusion that extends the research beyond the scope of the paper by suggesting potential future research directions or discussing the broader implications of the findings. This type of conclusion is often used in more theoretical or exploratory research papers.

The conclusion in a research paper serves several important purposes:

  • Offers Implications and Recommendations : Your research paper conclusion is an excellent place to discuss the broader implications of your research and suggest potential areas for further study. It’s also an opportunity to offer practical recommendations based on your findings.
  • Provides Closure : A good research paper conclusion provides a sense of closure to your paper. It should leave the reader with a feeling that they have reached the end of a well-structured and thought-provoking research project.
  • Leaves a Lasting Impression : Writing a well-crafted research paper conclusion leaves a lasting impression on your readers. It’s your final opportunity to leave them with a new idea, a call to action, or a memorable quote.

Writing a strong conclusion for your research paper is essential to leave a lasting impression on your readers. Here’s a step-by-step process to help you create and know what to put in the conclusion of a research paper: 2

  • Research Statement : Begin your research paper conclusion by restating your research statement. This reminds the reader of the main point you’ve been trying to prove throughout your paper. Keep it concise and clear.
  • Key Points : Summarize the main arguments and key points you’ve made in your paper. Avoid introducing new information in the research paper conclusion. Instead, provide a concise overview of what you’ve discussed in the body of your paper.
  • Address the Research Questions : If your research paper is based on specific research questions or hypotheses, briefly address whether you’ve answered them or achieved your research goals. Discuss the significance of your findings in this context.
  • Significance : Highlight the importance of your research and its relevance in the broader context. Explain why your findings matter and how they contribute to the existing knowledge in your field.
  • Implications : Explore the practical or theoretical implications of your research. How might your findings impact future research, policy, or real-world applications? Consider the “so what?” question.
  • Future Research : Offer suggestions for future research in your area. What questions or aspects remain unanswered or warrant further investigation? This shows that your work opens the door for future exploration.
  • Closing Thought : Conclude your research paper conclusion with a thought-provoking or memorable statement. This can leave a lasting impression on your readers and wrap up your paper effectively. Avoid introducing new information or arguments here.
  • Proofread and Revise : Carefully proofread your conclusion for grammar, spelling, and clarity. Ensure that your ideas flow smoothly and that your conclusion is coherent and well-structured.

Remember that a well-crafted research paper conclusion is a reflection of the strength of your research and your ability to communicate its significance effectively. It should leave a lasting impression on your readers and tie together all the threads of your paper. Now you know how to start the conclusion of a research paper and what elements to include to make it impactful, let’s look at a research paper conclusion sample.

how to conclude research paper

The research paper conclusion is a crucial part of your paper as it provides the final opportunity to leave a strong impression on your readers. In the research paper conclusion, summarize the main points of your research paper by restating your research statement, highlighting the most important findings, addressing the research questions or objectives, explaining the broader context of the study, discussing the significance of your findings, providing recommendations if applicable, and emphasizing the takeaway message. The main purpose of the conclusion is to remind the reader of the main point or argument of your paper and to provide a clear and concise summary of the key findings and their implications. All these elements should feature on your list of what to put in the conclusion of a research paper to create a strong final statement for your work.

A strong conclusion is a critical component of a research paper, as it provides an opportunity to wrap up your arguments, reiterate your main points, and leave a lasting impression on your readers. Here are the key elements of a strong research paper conclusion: 1. Conciseness : A research paper conclusion should be concise and to the point. It should not introduce new information or ideas that were not discussed in the body of the paper. 2. Summarization : The research paper conclusion should be comprehensive enough to give the reader a clear understanding of the research’s main contributions. 3 . Relevance : Ensure that the information included in the research paper conclusion is directly relevant to the research paper’s main topic and objectives; avoid unnecessary details. 4 . Connection to the Introduction : A well-structured research paper conclusion often revisits the key points made in the introduction and shows how the research has addressed the initial questions or objectives. 5. Emphasis : Highlight the significance and implications of your research. Why is your study important? What are the broader implications or applications of your findings? 6 . Call to Action : Include a call to action or a recommendation for future research or action based on your findings.

The length of a research paper conclusion can vary depending on several factors, including the overall length of the paper, the complexity of the research, and the specific journal requirements. While there is no strict rule for the length of a conclusion, but it’s generally advisable to keep it relatively short. A typical research paper conclusion might be around 5-10% of the paper’s total length. For example, if your paper is 10 pages long, the conclusion might be roughly half a page to one page in length.

In general, you do not need to include citations in the research paper conclusion. Citations are typically reserved for the body of the paper to support your arguments and provide evidence for your claims. However, there may be some exceptions to this rule: 1. If you are drawing a direct quote or paraphrasing a specific source in your research paper conclusion, you should include a citation to give proper credit to the original author. 2. If your conclusion refers to or discusses specific research, data, or sources that are crucial to the overall argument, citations can be included to reinforce your conclusion’s validity.

The conclusion of a research paper serves several important purposes: 1. Summarize the Key Points 2. Reinforce the Main Argument 3. Provide Closure 4. Offer Insights or Implications 5. Engage the Reader. 6. Reflect on Limitations

Remember that the primary purpose of the research paper conclusion is to leave a lasting impression on the reader, reinforcing the key points and providing closure to your research. It’s often the last part of the paper that the reader will see, so it should be strong and well-crafted.

Research Paper Conclusion

Definition:

A research paper conclusion is the final section of a research paper that summarizes the key findings, significance, and implications of the research. It is the writer’s opportunity to synthesize the information presented in the paper, draw conclusions, and make recommendations for future research or actions.

The conclusion should provide a clear and concise summary of the research paper, reiterating the research question or problem, the main results, and the significance of the findings. It should also discuss the limitations of the study and suggest areas for further research.

Parts of Research Paper Conclusion

The parts of a research paper conclusion typically include:

Restatement of the Thesis

The conclusion should begin by restating the thesis statement from the introduction in a different way. This helps to remind the reader of the main argument or purpose of the research.

Summary of Key Findings

The conclusion should summarize the main findings of the research, highlighting the most important results and conclusions. This section should be brief and to the point.

Implications and Significance

In this section, the researcher should explain the implications and significance of the research findings. This may include discussing the potential impact on the field or industry, highlighting new insights or knowledge gained, or pointing out areas for future research.

Limitations and Recommendations

It is important to acknowledge any limitations or weaknesses of the research and to make recommendations for how these could be addressed in future studies. This shows that the researcher is aware of the potential limitations of their work and is committed to improving the quality of research in their field.

Concluding Statement

The conclusion should end with a strong concluding statement that leaves a lasting impression on the reader. This could be a call to action, a recommendation for further research, or a final thought on the topic.

How to Write Research Paper Conclusion

Here are some steps you can follow to write an effective research paper conclusion:

  • Restate the research problem or question: Begin by restating the research problem or question that you aimed to answer in your research. This will remind the reader of the purpose of your study.
  • Summarize the main points: Summarize the key findings and results of your research. This can be done by highlighting the most important aspects of your research and the evidence that supports them.
  • Discuss the implications: Discuss the implications of your findings for the research area and any potential applications of your research. You should also mention any limitations of your research that may affect the interpretation of your findings.
  • Provide a conclusion : Provide a concise conclusion that summarizes the main points of your paper and emphasizes the significance of your research. This should be a strong and clear statement that leaves a lasting impression on the reader.
  • Offer suggestions for future research: Lastly, offer suggestions for future research that could build on your findings and contribute to further advancements in the field.

Remember that the conclusion should be brief and to the point, while still effectively summarizing the key findings and implications of your research.

Example of Research Paper Conclusion

Here’s an example of a research paper conclusion:

Conclusion :

In conclusion, our study aimed to investigate the relationship between social media use and mental health among college students. Our findings suggest that there is a significant association between social media use and increased levels of anxiety and depression among college students. This highlights the need for increased awareness and education about the potential negative effects of social media use on mental health, particularly among college students.

Despite the limitations of our study, such as the small sample size and self-reported data, our findings have important implications for future research and practice. Future studies should aim to replicate our findings in larger, more diverse samples, and investigate the potential mechanisms underlying the association between social media use and mental health. In addition, interventions should be developed to promote healthy social media use among college students, such as mindfulness-based approaches and social media detox programs.

Overall, our study contributes to the growing body of research on the impact of social media on mental health, and highlights the importance of addressing this issue in the context of higher education. By raising awareness and promoting healthy social media use among college students, we can help to reduce the negative impact of social media on mental health and improve the well-being of young adults.

Purpose of Research Paper Conclusion

The purpose of a research paper conclusion is to provide a summary and synthesis of the key findings, significance, and implications of the research presented in the paper. The conclusion serves as the final opportunity for the writer to convey their message and leave a lasting impression on the reader.

The conclusion should restate the research problem or question, summarize the main results of the research, and explain their significance. It should also acknowledge the limitations of the study and suggest areas for future research or action.

Overall, the purpose of the conclusion is to provide a sense of closure to the research paper and to emphasize the importance of the research and its potential impact. It should leave the reader with a clear understanding of the main findings and why they matter. The conclusion serves as the writer’s opportunity to showcase their contribution to the field and to inspire further research and action.

When to Write Research Paper Conclusion

The conclusion of a research paper should be written after the body of the paper has been completed. It should not be written until the writer has thoroughly analyzed and interpreted their findings and has written a complete and cohesive discussion of the research.

Before writing the conclusion, the writer should review their research paper and consider the key points that they want to convey to the reader. They should also review the research question, hypotheses, and methodology to ensure that they have addressed all of the necessary components of the research.

Once the writer has a clear understanding of the main findings and their significance, they can begin writing the conclusion. The conclusion should be written in a clear and concise manner, and should reiterate the main points of the research while also providing insights and recommendations for future research or action.

Characteristics of Research Paper Conclusion

The characteristics of a research paper conclusion include:

  • Clear and concise: The conclusion should be written in a clear and concise manner, summarizing the key findings and their significance.
  • Comprehensive: The conclusion should address all of the main points of the research paper, including the research question or problem, the methodology, the main results, and their implications.
  • Future-oriented : The conclusion should provide insights and recommendations for future research or action, based on the findings of the research.
  • Impressive : The conclusion should leave a lasting impression on the reader, emphasizing the importance of the research and its potential impact.
  • Objective : The conclusion should be based on the evidence presented in the research paper, and should avoid personal biases or opinions.
  • Unique : The conclusion should be unique to the research paper and should not simply repeat information from the introduction or body of the paper.

Advantages of Research Paper Conclusion

The advantages of a research paper conclusion include:

  • Summarizing the key findings : The conclusion provides a summary of the main findings of the research, making it easier for the reader to understand the key points of the study.
  • Emphasizing the significance of the research: The conclusion emphasizes the importance of the research and its potential impact, making it more likely that readers will take the research seriously and consider its implications.

The conclusion of a research paper needs to summarize the content and purpose of the paper without seeming too wooden or dry. Every basic conclusion must share several key elements, but there are also several tactics you can play around with to craft a more effective conclusion and several you should avoid to prevent yourself from weakening your paper's conclusion. Here are some writing tips to keep in mind when creating a conclusion for your next research paper.

Sample Conclusions

Writing a basic conclusion.

Step 1 Restate the topic.

  • Do not spend a great amount of time or space restating your topic.
  • A good research paper will make the importance of your topic apparent, so you do not need to write an elaborate defense of your topic in the conclusion.
  • Usually a single sentence is all you need to restate your topic.
  • An example would be if you were writing a paper on the epidemiology of infectious disease, you might say something like "Tuberculosis is a widespread infectious disease that affects millions of people worldwide every year."
  • Yet another example from the humanities would be a paper about the Italian Renaissance: "The Italian Renaissance was an explosion of art and ideas centered around artists, writers, and thinkers in Florence."

Step 2 Restate your thesis.

  • A thesis is a narrowed, focused view on the topic at hand.
  • This statement should be rephrased from the thesis you included in your introduction. It should not be identical or too similar to the sentence you originally used.
  • Try re-wording your thesis statement in a way that complements your summary of the topic of your paper in your first sentence of your conclusion.
  • An example of a good thesis statement, going back to the paper on tuberculosis, would be "Tuberculosis is a widespread disease that affects millions of people worldwide every year. Due to the alarming rate of the spread of tuberculosis, particularly in poor countries, medical professionals are implementing new strategies for the diagnosis, treatment, and containment of this disease ."

Step 3 Briefly summarize your main points.

  • A good way to go about this is to re-read the topic sentence of each major paragraph or section in the body of your paper.
  • Find a way to briefly restate each point mentioned in each topic sentence in your conclusion. Do not repeat any of the supporting details used within your body paragraphs.
  • Under most circumstances, you should avoid writing new information in your conclusion. This is especially true if the information is vital to the argument or research presented in your paper.
  • For example, in the TB paper you could summarize the information. "Tuberculosis is a widespread disease that affects millions of people worldwide. Due to the alarming rate of the spread of tuberculosis, particularly in poor countries, medical professionals are implementing new strategies for the diagnosis, treatment, and containment of this disease. In developing countries, such as those in Africa and Southeast Asia, the rate of TB infections is soaring. Crowded conditions, poor sanitation, and lack of access to medical care are all compounding factors in the spread of the disease. Medical experts, such as those from the World Health Organization are now starting campaigns to go into communities in developing countries and provide diagnostic testing and treatments. However, the treatments for TB are very harsh and have many side effects. This leads to patient non-compliance and spread of multi-drug resistant strains of the disease."

Step 4 Add the points up.

  • Note that this is not needed for all research papers.
  • If you already fully explained what the points in your paper mean or why they are significant, you do not need to go into them in much detail in your conclusion. Simply restating your thesis or the significance of your topic should suffice.
  • It is always best practice to address important issues and fully explain your points in the body of your paper. The point of a conclusion to a research paper is to summarize your argument for the reader and, perhaps, to call the reader to action if needed.

Step 5 Make a call to action when appropriate.

  • Note that a call for action is not essential to all conclusions. A research paper on literary criticism, for instance, is less likely to need a call for action than a paper on the effect that television has on toddlers and young children.
  • A paper that is more likely to call readers to action is one that addresses a public or scientific need. Let's go back to our example of tuberculosis. This is a very serious disease that is spreading quickly and with antibiotic-resistant forms.
  • A call to action in this research paper would be a follow-up statement that might be along the lines of "Despite new efforts to diagnose and contain the disease, more research is needed to develop new antibiotics that will treat the most resistant strains of tuberculosis and ease the side effects of current treatments."

Step 6 Answer the “so what” question.

  • For example, if you are writing a history paper, then you might discuss how the historical topic you discussed matters today. If you are writing about a foreign country, then you might use the conclusion to discuss how the information you shared may help readers understand their own country.

Making Your Conclusion as Effective as Possible

Step 1 Stick with a basic synthesis of information.

  • Since this sort of conclusion is so basic, you must aim to synthesize the information rather than merely summarizing it.
  • Instead of merely repeating things you already said, rephrase your thesis and supporting points in a way that ties them all together.
  • By doing so, you make your research paper seem like a "complete thought" rather than a collection of random and vaguely related ideas.

Step 2 Bring things full circle.

  • Ask a question in your introduction. In your conclusion, restate the question and provide a direct answer.
  • Write an anecdote or story in your introduction but do not share the ending. Instead, write the conclusion to the anecdote in the conclusion of your paper.
  • For example, if you wanted to get more creative and put a more humanistic spin on a paper on tuberculosis, you might start your introduction with a story about a person with the disease, and refer to that story in your conclusion. For example, you could say something like this before you re-state your thesis in your conclusion: "Patient X was unable to complete the treatment for tuberculosis due to severe side effects and unfortunately succumbed to the disease."
  • Use the same concepts and images introduced in your introduction in your conclusion. The images may or may not appear at other points throughout the research paper.

Step 3 Close with logic.

  • Include enough information about your topic to back the statement up but do not get too carried away with excess detail.
  • If your research did not provide you with a clear-cut answer to a question posed in your thesis, do not be afraid to indicate as much.
  • Restate your initial hypothesis and indicate whether you still believe it or if the research you performed has begun swaying your opinion.
  • Indicate that an answer may still exist and that further research could shed more light on the topic at hand.

Step 4 Pose a question.

  • This may not be appropriate for all types of research papers. Most research papers, such as one on effective treatment for diseases, will have the information to make the case for a particular argument already in the paper.
  • A good example of a paper that might ask a question of the reader in the ending is one about a social issue, such as poverty or government policy.
  • Ask a question that will directly get at the heart or purpose of the paper. This question is often the same question, or some version of it, that you may have started with when you began your research.
  • Make sure that the question can be answered by the evidence presented in your paper.
  • If desired you can briefly summarize the answer after stating the question. You could also leave the question hanging for the reader to answer, though.

Step 5 Make a suggestion.

  • Even without a call to action, you can still make a recommendation to your reader.
  • For instance, if you are writing about a topic like third-world poverty, you can various ways for the reader to assist in the problem without necessarily calling for more research.
  • Another example would be, in a paper about treatment for drug-resistant tuberculosis, you could suggest donating to the World Health Organization or research foundations that are developing new treatments for the disease.

Avoiding Common Pitfalls

Step 1 Avoid saying

  • These sayings usually sound stiff, unnatural, or trite when used in writing.
  • Moreover, using a phrase like "in conclusion" to begin your conclusion is a little too straightforward and tends to lead to a weak conclusion. A strong conclusion can stand on its own without being labeled as such.

Step 2 Do not wait until the conclusion to state your thesis.

  • Always state the main argument or thesis in the introduction. A research paper is an analytical discussion of an academic topic, not a mystery novel.
  • A good, effective research paper will allow your reader to follow your main argument from start to finish.
  • This is why it is best practice to start your paper with an introduction that states your main argument and to end the paper with a conclusion that re-states your thesis for re-iteration.

Step 3 Leave out new information.

  • All significant information should be introduced in the body of the paper.
  • Supporting evidence expands the topic of your paper by making it appear more detailed. A conclusion should narrow the topic to a more general point.
  • A conclusion should only summarize what you have already stated in the body of your paper.
  • You may suggest further research or a call to action, but you should not bring in any new evidence or facts in the conclusion.

Step 4 Avoid changing the tone of the paper.

  • Most often, a shift in tone occurs when a research paper with an academic tone gives an emotional or sentimental conclusion.
  • Even if the topic of the paper is of personal significance for you, you should not indicate as much in your paper.
  • If you want to give your paper a more humanistic slant, you could start and end your paper with a story or anecdote that would give your topic more personal meaning to the reader.
  • This tone should be consistent throughout the paper, however.

Step 5 Make no apologies.

  • Apologetic statements include phrases like "I may not be an expert" or "This is only my opinion."
  • Statements like this can usually be avoided by refraining from writing in the first-person.
  • Avoid any statements in the first-person. First-person is generally considered to be informal and does not fit with the formal tone of a research paper.

To write a conclusion for a research paper, start by restating your thesis statement to remind your readers what your main topic is and bring everything full circle. Then, briefly summarize all of the main points you made throughout your paper, which will help remind your readers of everything they learned. You might also want to include a call to action if you think more research or work needs to be done on your topic by writing something like, "Despite efforts to contain the disease, more research is needed to develop antibiotics." Finally, end your conclusion by explaining the broader context of your topic and why your readers should care about it, which will help them understand why your topic is relevant and important.

What Is a Conclusion in Research Papers

A conclusion in research paper is the final piece of the puzzle, the last chapter in the story, the grand finale of a long and arduous journey. It is the point where the researcher can finally step back and say, 'I have found what I was looking for.' But it is more than just a summary of the findings. A conclusion is a reflection on the entire research process, a chance for the researcher to evaluate the strengths and weaknesses of their methodology and to make recommendations for future research. It is a time to celebrate successes, acknowledge limitations, and offer suggestions for improvement.

You may know how to start a research paper ; however, making a compelling ending requires a thorough understanding too. A conclusion is an opportunity to connect the research findings to a larger context, discuss how the results contribute to the broader field of study and suggest possible applications in real-world scenarios. It is a moment of closure but also a starting point for new avenues of inquiry.

So, let's delve into the following sections to find out how to write a conclusion for a research paper that will leave a lasting impression on your audience.

What to Avoid in Your Research Paper Conclusion

Outline for a Research Paper Conclusion

When wondering how to make a research paper outline , the first step is to get familiar with the general structure. Here we prepared a research paper conclusion example, so let's take a close look at what information to include in a conclusion outline:

I. Summary of main findings

  • Briefly summarize the main findings of the research, including any significant results or discoveries made.

II. Restate the research question/objective

  • Restate the thesis statement or objective and indicate whether it was answered or achieved.

III. Discuss the implications of the findings

  • Discuss the implications of the findings and explain why they matter, including any practical applications or theoretical implications.

IV. Acknowledge limitations and suggest future research

  • Acknowledge any limitations or weaknesses of the study and suggest directions for future research, including any areas where further investigation is needed.

V. Concluding statement

  • Conclude your final paragraph with a statement that ties together the main points of the conclusion research paper and emphasizes their significance.

Tips on How to Make a Conclusion in Research

By following these tips, you won't have to wonder 'how to make a conclusion in research' anymore and will effectively highlight its significance.

Research Paper Conclusion

  • Emphasize the significance of the findings: When discussing the implications, emphasize the practical or theoretical implications. Use language that emphasizes the importance of the findings and how they contribute to the broader field of study. For example, 'The study findings have important implications for clinical practice and highlight the need for further research in this area.'
  • Tie back to the introduction: When concluding, tie the findings back to the introduction by reminding readers of the original purpose of the research. This helps to provide closure to the research and emphasizes the significance of the findings. For example, 'This study has successfully answered the research question of whether stress is a risk factor for heart disease in middle-aged adults, and provides important insights into the relationship between stress and cardiovascular health.'
  • Avoid introducing new information: It's important to avoid introducing new information in the conclusion, as this can confuse readers and detract from the key arguments of the research. Stick to summarizing the main findings, discussing the implications, acknowledging limitations, and suggesting future research possibilities.
  • Use clear and concise language: When making a conclusion, use clear and concise language. Avoid using technical jargon or overly complex language; instead, focus on using language accessible to a broad audience.
  • End with a strong concluding statement: End your paper's conclusion with a strong concluding statement that ties together the main points and emphasizes their significance. This provides closure to the research and leaves readers with a lasting impression. Here is a conclusion in research example: 'Overall, the findings of this study provide important insights into the relationship between X and Y and highlight the need for further research in this area.'

How to Develop a Compelling Conclusion

Here are some main points to help you not just summarize the key thoughts of your work, but to go deeper to warrant a better grade:

  • If you have been writing about a contemporary problem, talk about what can happen if the problem is not solved, but do not add new information. Do not bring in new evidence or new facts.
  • Don’t hesitate to offer or to recommend some course of action.
  • Use relevant quotations or expert opinions to make your conclusion more authoritative.
  • Repeat a key statistic, fact, or even a visual image that represents the main point of your paper.
  • Express personal reflection. You can even talk about your own life experiences.
  • Interpret the results in your own way to give them a fresh perspective. Do not be afraid to be a researcher who introduces something new—even for the most common problems.
  • Finish your conclusions with a short, but powerful message which will help others remember your study. This message is something that can differentiate you from others.
  • Do not say "in conclusion" or similar sayings. This includes "in summary" or "in closing." Why? These sayings sound a bit unnatural and stiff. They make your work appear too formal and pragmatic. A strong conclusion does not need the word - “In conclusion”. It will stand on its own.
  • Use the same consistent tone through your entire paper. It sounds unnatural if you suddenly use an absolutely different tone or style of presenting the information.
  • Check your entire paper to make sure that you have not left any really important points behind.

How to Make a Conclusion Effective Rhetorically

Here are some unique tips on how to start conclusion in research rhetorically from our service:

  • Use rhetorical questions : Rhetorical questions are a powerful tool that can help to engage readers and prompt them to think critically about the research. For example, 'What impact will these findings have on the field of X? How can we use these findings to improve clinical practice?'
  • Use strong language: Using strong, impactful language can help emphasize the research's significance and leave a lasting impression on readers. For example, 'These findings have the potential to revolutionize the way we approach X, and could have far-reaching implications for future research in this area.'
  • Use repetition: Repetition can be an effective rhetorical tool that can help to reinforce key points and leave a lasting impression on readers. For example, repeating a phrase such as 'These findings underscore the importance of...' can help emphasize the research's significance.
  • Use anecdotes : Using anecdotes or stories can help to make the research more relatable and engaging for readers. For example, sharing a personal story or case study that illustrates the research's practical applications can help emphasize its significance.
  • Use vivid imagery : It can help bring the research to life and make it more memorable for readers. For example, using descriptive language to describe the impact of the research, such as 'This study sheds new light on X, illuminating a path forward for researchers in this field.'

Making a Conclusion Effective Logically

By using these logical strategies from our custom dissertation writing , you can make your research paper conclusion more coherent, persuasive, and effective.

  • Use logical transitions : To make the conclusion flow smoothly and logically, use transition words and phrases such as 'therefore,' 'thus,' 'consequently,' and 'in conclusion.' This helps to signal to readers that the conclusion is a logical extension of the research that has been presented.
  • Summarize key findings in order : To make the conclusion logical, summarize the key findings of the research in the order in which they were presented. This helps readers follow the research's progression and understand how the various findings fit together.
  • Address potential counterarguments: Researchers can demonstrate a thorough and logical approach to their research by acknowledging and addressing these potential criticisms.
  • Use quantitative data: This helps provide concrete evidence for the conclusions being drawn and makes the research more convincing.
  • Provide a clear and concise summary: This helps readers understand the main takeaways from the research and provides a logical conclusion.

Things to Avoid in the Conclusion of Your Research Paper

By avoiding these common pitfalls, you can ensure that their conclusions are clear, concise, and effective in summarizing their research's main findings and implications.

Avoid in Your Research Paper Conclusion

  • Don't introduce new information: The conclusion is not the place to introduce new information or data that was not discussed in the main body of the paper. Stick to summarizing the key findings and insights that were already presented.
  • Don't repeat information : While it's important to summarize key findings in the example of conclusion in research paper, don't simply repeat information already presented earlier. Instead, focus on synthesizing and connecting the various findings in a new way.
  • Don't make unsupported claims: Avoid making sweeping or unsupported claims in the conclusion. Make sure that all conclusions are backed up by the data and evidence presented in the main body of the paper.
  • Don't be overly emotional: While being passionate about your research topic is important, avoid being overly emotional or sentimental in the conclusion. Stick to a professional and objective tone.
  • Don't end abruptly: Don't end the conclusion of research paper abruptly without providing a clear sense of closure. Instead, summarize the main points and insights, and consider ending with a call to action or a suggestion for future research.

The conclusion is intended to help the reader understand why your research should matter to them after they have finished reading the paper. A conclusion is not merely a summary of the main topics covered or a re-statement of your research problem, but a synthesis of key points and, if applicable, where you recommend new areas for future research. For most college-level research papers, one or two well-developed paragraphs is sufficient for a conclusion, although in some cases, more paragraphs may be required in summarizing key findings and their significance.

Importance of a Good Conclusion

A well-written conclusion provides you with important opportunities to demonstrate to the reader your understanding of the research problem. These include:

  • Presenting the last word on the issues you raised in your paper . Just as the introduction gives a first impression to your reader, the conclusion offers a chance to leave a lasting impression. Do this, for example, by highlighting key findings in your analysis that advance new understanding about the research problem, that are unusual or unexpected, or that have important implications applied to practice.
  • Summarizing your thoughts and conveying the larger significance of your study . The conclusion is an opportunity to succinctly re-emphasize  the "So What?" question by placing the study within the context of how your research advances past research about the topic.
  • Identifying how a gap in the literature has been addressed . The conclusion can be where you describe how a previously identified gap in the literature [described in your literature review section] has been filled by your research.
  • Demonstrating the importance of your ideas . Don't be shy. The conclusion offers you the opportunity to elaborate on the impact and significance of your findings. This is particularly important if your study approached examining the research problem from an unusual or innovative perspective.
  • Introducing possible new or expanded ways of thinking about the research problem . This does not refer to introducing new information [which should be avoided], but to offer new insight and creative approaches for framing or contextualizing the research problem based on the results of your study.

Structure and Writing Style

I.  General Rules

The function of your paper's conclusion is to restate the main argument . It reminds the reader of the strengths of your main argument(s) and reiterates the most important evidence supporting those argument(s). Do this by stating clearly the context, background, and necessity of pursuing the research problem you investigated in relation to an issue, controversy, or a gap found in the literature. Make sure, however, that your conclusion is not simply a repetitive summary of the findings. This reduces the impact of the argument(s) you have developed in your essay.

When writing the conclusion to your paper, follow these general rules:

  • Present your conclusions in clear, simple language. Re-state the purpose of your study, then describe how your findings differ or support those of other studies and why [i.e., what were the unique or new contributions your study made to the overall research about your topic?].
  • Do not simply reiterate your findings or the discussion of your results. Provide a synthesis of arguments presented in the paper to show how these converge to address the research problem and the overall objectives of your study.
  • Indicate opportunities for future research if you haven't already done so in the discussion section of your paper. Highlighting the need for further research provides the reader with evidence that you have an in-depth awareness of the research problem and that further investigations should take place.

Consider the following points to help ensure your conclusion is presented well:

  • If the argument or purpose of your paper is complex, you may need to summarize the argument for your reader.
  • If, prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the end of your paper to describe your main points and explain their significance.
  • Move from a detailed to a general level of consideration that returns the topic to the context provided by the introduction or within a new context that emerges from the data. 

The conclusion also provides a place for you to persuasively and succinctly restate the research problem, given that the reader has now been presented with all the information about the topic . Depending on the discipline you are writing in, the concluding paragraph may contain your reflections on the evidence presented. However, the nature of being introspective about the research you have conducted will depend on the topic and whether your professor wants you to express your observations in this way.

NOTE : If asked to think introspectively about the topics, do not delve into idle speculation. Being introspective means looking within yourself as an author to try and understand an issue more deeply, not to guess at possible outcomes or make up scenarios not supported by the evidence.

II.  Developing a Compelling Conclusion

Although an effective conclusion needs to be clear and succinct, it does not need to be written passively or lack a compelling narrative. Strategies to help you move beyond merely summarizing the key points of your research paper may include any of the following strategies:

  • If your essay deals with a critical, contemporary problem, warn readers of the possible consequences of not attending to the problem proactively.
  • Recommend a specific course or courses of action that, if adopted, could address a specific problem in practice or in the development of new knowledge.
  • Cite a relevant quotation or expert opinion already noted in your paper in order to lend authority and support to the conclusion(s) you have reached [a good place to look is research from your literature review].
  • Explain the consequences of your research in a way that elicits action or demonstrates urgency in seeking change.
  • Restate a key statistic, fact, or visual image to emphasize the most important finding of your paper.
  • If your discipline encourages personal reflection, illustrate your concluding point by drawing from your own life experiences.
  • Return to an anecdote, an example, or a quotation that you presented in your introduction, but add further insight derived from the findings of your study; use your interpretation of results to recast it in new or important ways.
  • Provide a "take-home" message in the form of a succinct, declarative statement that you want the reader to remember about your study.

III. Problems to Avoid

Failure to be concise Your conclusion section should be concise and to the point. Conclusions that are too lengthy often have unnecessary information in them. The conclusion is not the place for details about your methodology or results. Although you should give a summary of what was learned from your research, this summary should be relatively brief, since the emphasis in the conclusion is on the implications, evaluations, insights, and other forms of analysis that you make. Strategies for writing concisely can be found here .

Failure to comment on larger, more significant issues In the introduction, your task was to move from the general [the field of study] to the specific [the research problem]. However, in the conclusion, your task is to move from a specific discussion [your research problem] back to a general discussion [i.e., how your research contributes new understanding or fills an important gap in the literature]. In short, the conclusion is where you should place your research within a larger context [visualize your paper as an hourglass--start with a broad introduction and review of the literature, move to the specific analysis and discussion, conclude with a broad summary of the study's implications and significance].

Failure to reveal problems and negative results Negative aspects of the research process should never be ignored. These are problems, deficiencies, or challenges encountered during your study should be summarized as a way of qualifying your overall conclusions. If you encountered negative or unintended results [i.e., findings that are validated outside the research context in which they were generated], you must report them in the results section and discuss their implications in the discussion section of your paper. In the conclusion, use your summary of the negative results as an opportunity to explain their possible significance and/or how they may form the basis for future research.

Failure to provide a clear summary of what was learned In order to be able to discuss how your research fits within your field of study [and possibly the world at large], you need to summarize briefly and succinctly how it contributes to new knowledge or a new understanding about the research problem. This element of your conclusion may be only a few sentences long.

Failure to match the objectives of your research Often research objectives in the social sciences change while the research is being carried out. This is not a problem unless you forget to go back and refine the original objectives in your introduction. As these changes emerge they must be documented so that they accurately reflect what you were trying to accomplish in your research [not what you thought you might accomplish when you began].

Resist the urge to apologize If you've immersed yourself in studying the research problem, you presumably should know a good deal about it [perhaps even more than your professor!]. Nevertheless, by the time you have finished writing, you may be having some doubts about what you have produced. Repress those doubts! Don't undermine your authority by saying something like, "This is just one approach to examining this problem; there may be other, much better approaches that...." The overall tone of your conclusion should convey confidence to the reader.

Writing Tip

Don't Belabor the Obvious!

Avoid phrases like "in conclusion...," "in summary...," or "in closing...." These phrases can be useful, even welcome, in oral presentations. But readers can see by the tell-tale section heading and number of pages remaining to read, when an essay is about to end. You'll irritate your readers if you belabor the obvious.

Another Writing Tip

New Insight, Not New Information!

Don't surprise the reader with new information in your conclusion that was never referenced anywhere else in the paper and, as such, the conclusion rarely has citations to sources. If you have new information to present, add it to the discussion or other appropriate section of the paper. Note that, although no actual new information is introduced, the conclusion, along with the discussion section, is where you offer your most "original" contributions in the paper; the conclusion is where you describe the value of your research, demonstrate that you understand the material that you’ve presented, and locate your findings within the larger context of scholarship on the topic, including describing how your research contributes new insights or valuable insight to that scholarship.

How to write a strong conclusion for your research paper

Last updated

17 February 2024

Reviewed by

Writing a research paper is a chance to share your knowledge and hypothesis. It's an opportunity to demonstrate your many hours of research and prove your ability to write convincingly.

Ideally, by the end of your research paper, you'll have brought your readers on a journey to reach the conclusions you've pre-determined. However, if you don't stick the landing with a good conclusion, you'll risk losing your reader’s trust.

Writing a strong conclusion for your research paper involves a few important steps, including restating the thesis and summing up everything properly.

Find out what to include and what to avoid, so you can effectively demonstrate your understanding of the topic and prove your expertise.

  • Why is a good conclusion important?

A good conclusion can cement your paper in the reader’s mind. Making a strong impression in your introduction can draw your readers in, but it's the conclusion that will inspire them.

  • What to include in a research paper conclusion

There are a few specifics you should include in your research paper conclusion. Offer your readers some sense of urgency or consequence by pointing out why they should care about the topic you have covered. Discuss any common problems associated with your topic and provide suggestions as to how these problems can be solved or addressed.

The conclusion should include a restatement of your initial thesis. Thesis statements are strengthened after you’ve presented supporting evidence (as you will have done in the paper), so make a point to reintroduce it at the end.

Finally, recap the main points of your research paper, highlighting the key takeaways you want readers to remember. If you've made multiple points throughout the paper, refer to the ones with the strongest supporting evidence.

  • Steps for writing a research paper conclusion

Many writers find the conclusion the most challenging part of any research project . By following these three steps, you'll be prepared to write a conclusion that is effective and concise.

  • Step 1: Restate the problem

Always begin by restating the research problem in the conclusion of a research paper. This serves to remind the reader of your hypothesis and refresh them on the main point of the paper. 

When restating the problem, take care to avoid using exactly the same words you employed earlier in the paper.

  • Step 2: Sum up the paper

After you've restated the problem, sum up the paper by revealing your overall findings. The method for this differs slightly, depending on whether you're crafting an argumentative paper or an empirical paper.

Argumentative paper: Restate your thesis and arguments

Argumentative papers involve introducing a thesis statement early on. In crafting the conclusion for an argumentative paper, always restate the thesis, outlining the way you've developed it throughout the entire paper.

It might be appropriate to mention any counterarguments in the conclusion, so you can demonstrate how your thesis is correct or how the data best supports your main points.

Empirical paper: Summarize research findings

Empirical papers break down a series of research questions. In your conclusion, discuss the findings your research revealed, including any information that surprised you.

Be clear about the conclusions you reached, and explain whether or not you expected to arrive at these particular ones.

  • Step 3: Discuss the implications of your research

Argumentative papers and empirical papers also differ in this part of a research paper conclusion. Here are some tips on crafting conclusions for argumentative and empirical papers.

Argumentative paper: Powerful closing statement

In an argumentative paper, you'll have spent a great deal of time expressing the opinions you formed after doing a significant amount of research. Make a strong closing statement in your argumentative paper's conclusion to share the significance of your work.

You can outline the next steps through a bold call to action, or restate how powerful your ideas turned out to be.

Empirical paper: Directions for future research

Empirical papers are broader in scope. They usually cover a variety of aspects and can include several points of view.

To write a good conclusion for an empirical paper, suggest the type of research that could be done in the future, including methods for further investigation or outlining ways other researchers might proceed.

If you feel your research had any limitations, even if they were outside your control, you could mention these in your conclusion.

After you finish outlining your conclusion, ask someone to read it and offer feedback. In any research project you're especially close to, it can be hard to identify problem areas. Having a close friend or someone whose opinion you value read the research paper and provide honest feedback can be invaluable. Take note of any suggested edits and consider incorporating them into your paper if they make sense.

  • Things to avoid in a research paper conclusion

Keep these aspects to avoid in mind as you're writing your conclusion and refer to them after you've created an outline.

Dry summary

Writing a memorable, succinct conclusion is arguably more important than a strong introduction. Take care to avoid just rephrasing your main points, and don't fall into the trap of repeating dry facts or citations.

You can provide a new perspective for your readers to think about or contextualize your research. Either way, make the conclusion vibrant and interesting, rather than a rote recitation of your research paper’s highlights.

Clichéd or generic phrasing

Your research paper conclusion should feel fresh and inspiring. Avoid generic phrases like "to sum up" or "in conclusion." These phrases tend to be overused, especially in an academic context and might turn your readers off.

The conclusion also isn't the time to introduce colloquial phrases or informal language. Retain a professional, confident tone consistent throughout your paper’s conclusion so it feels exciting and bold.

New data or evidence

While you should present strong data throughout your paper, the conclusion isn't the place to introduce new evidence. This is because readers are engaged in actively learning as they read through the body of your paper.

By the time they reach the conclusion, they will have formed an opinion one way or the other (hopefully in your favor!). Introducing new evidence in the conclusion will only serve to surprise or frustrate your reader.

Ignoring contradictory evidence

If your research reveals contradictory evidence, don't ignore it in the conclusion. This will damage your credibility as an expert and might even serve to highlight the contradictions.

Be as transparent as possible and admit to any shortcomings in your research, but don't dwell on them for too long.

Ambiguous or unclear resolutions

The point of a research paper conclusion is to provide closure and bring all your ideas together. You should wrap up any arguments you introduced in the paper and tie up any loose ends, while demonstrating why your research and data are strong.

Use direct language in your conclusion and avoid ambiguity. Even if some of the data and sources you cite are inconclusive or contradictory, note this in your conclusion to come across as confident and trustworthy.

  • Examples of research paper conclusions

Your research paper should provide a compelling close to the paper as a whole, highlighting your research and hard work. While the conclusion should represent your unique style, these examples offer a starting point:

Ultimately, the data we examined all point to the same conclusion: Encouraging a good work-life balance improves employee productivity and benefits the company overall. The research suggests that when employees feel their personal lives are valued and respected by their employers, they are more likely to be productive when at work. In addition, company turnover tends to be reduced when employees have a balance between their personal and professional lives. While additional research is required to establish ways companies can support employees in creating a stronger work-life balance, it's clear the need is there.

Social media is a primary method of communication among young people. As we've seen in the data presented, most young people in high school use a variety of social media applications at least every hour, including Instagram and Facebook. While social media is an avenue for connection with peers, research increasingly suggests that social media use correlates with body image issues. Young girls with lower self-esteem tend to use social media more often than those who don't log onto social media apps every day. As new applications continue to gain popularity, and as more high school students are given smartphones, more research will be required to measure the effects of prolonged social media use.

What are the different kinds of research paper conclusions?

There are no formal types of research paper conclusions. Ultimately, the conclusion depends on the outline of your paper and the type of research you’re presenting. While some experts note that research papers can end with a new perspective or commentary, most papers should conclude with a combination of both. The most important aspect of a good research paper conclusion is that it accurately represents the body of the paper.

Can I present new arguments in my research paper conclusion?

Research paper conclusions are not the place to introduce new data or arguments. The body of your paper is where you should share research and insights, where the reader is actively absorbing the content. By the time a reader reaches the conclusion of the research paper, they should have formed their opinion. Introducing new arguments in the conclusion can take a reader by surprise, and not in a positive way. It might also serve to frustrate readers.

How long should a research paper conclusion be?

There's no set length for a research paper conclusion. However, it's a good idea not to run on too long, since conclusions are supposed to be succinct. A good rule of thumb is to keep your conclusion around 5 to 10 percent of the paper's total length. If your paper is 10 pages, try to keep your conclusion under one page.

What should I include in a research paper conclusion?

A good research paper conclusion should always include a sense of urgency, so the reader can see how and why the topic should matter to them. You can also note some recommended actions to help fix the problem and some obstacles they might encounter. A conclusion should also remind the reader of the thesis statement, along with the main points you covered in the paper. At the end of the conclusion, add a powerful closing statement that helps cement the paper in the mind of the reader.

One of the most common questions we receive at the Writing Center is “what am I supposed to do in my conclusion?” This is a difficult question to answer because there’s no one right answer to what belongs in a conclusion. How you conclude your paper will depend on where you started—and where you traveled. It will also depend on the conventions and expectations of the discipline in which you are writing. For example, while the conclusion to a STEM paper could focus on questions for further study, the conclusion of a literature paper could include a quotation from your central text that can now be understood differently in light of what has been discussed in the paper. You should consult your instructor about expectations for conclusions in a particular discipline.

With that in mind, here are some general guidelines you might find helpful to use as you think about your conclusion.  

Begin with the “what”  

In a short paper—even a research paper—you don’t need to provide an exhaustive summary as part of your conclusion. But you do need to make some kind of transition between your final body paragraph and your concluding paragraph. This may come in the form of a few sentences of summary. Or it may come in the form of a sentence that brings your readers back to your thesis or main idea and reminds your readers where you began and how far you have traveled.

So, for example, in a paper about the relationship between ADHD and rejection sensitivity, Vanessa Roser begins by introducing readers to the fact that researchers have studied the relationship between the two conditions and then provides her explanation of that relationship. Here’s her thesis: “While socialization may indeed be an important factor in RS, I argue that individuals with ADHD may also possess a neurological predisposition to RS that is exacerbated by the differing executive and emotional regulation characteristic of ADHD.”

In her final paragraph, Roser reminds us of where she started by echoing her thesis: “This literature demonstrates that, as with many other conditions, ADHD and RS share a delicately intertwined pattern of neurological similarities that is rooted in the innate biology of an individual’s mind, a connection that cannot be explained in full by the behavioral mediation hypothesis.”  

Highlight the “so what”  

At the beginning of your paper, you explain to your readers what’s at stake—why they should care about the argument you’re making. In your conclusion, you can bring readers back to those stakes by reminding them why your argument is important in the first place. You can also draft a few sentences that put those stakes into a new or broader context.

In the conclusion to her paper about ADHD and RS, Roser echoes the stakes she established in her introduction—that research into connections between ADHD and RS has led to contradictory results, raising questions about the “behavioral mediation hypothesis.”

She writes, “as with many other conditions, ADHD and RS share a delicately intertwined pattern of neurological similarities that is rooted in the innate biology of an individual’s mind, a connection that cannot be explained in full by the behavioral mediation hypothesis.”  

Leave your readers with the “now what”  

After the “what” and the “so what,” you should leave your reader with some final thoughts. If you have written a strong introduction, your readers will know why you have been arguing what you have been arguing—and why they should care. And if you’ve made a good case for your thesis, then your readers should be in a position to see things in a new way, understand new questions, or be ready for something that they weren’t ready for before they read your paper.

In her conclusion, Roser offers two “now what” statements. First, she explains that it is important to recognize that the flawed behavioral mediation hypothesis “seems to place a degree of fault on the individual. It implies that individuals with ADHD must have elicited such frequent or intense rejection by virtue of their inadequate social skills, erasing the possibility that they may simply possess a natural sensitivity to emotion.” She then highlights the broader implications for treatment of people with ADHD, noting that recognizing the actual connection between rejection sensitivity and ADHD “has profound implications for understanding how individuals with ADHD might best be treated in educational settings, by counselors, family, peers, or even society as a whole.”

To find your own “now what” for your essay’s conclusion, try asking yourself these questions:

  • What can my readers now understand, see in a new light, or grapple with that they would not have understood in the same way before reading my paper? Are we a step closer to understanding a larger phenomenon or to understanding why what was at stake is so important?  
  • What questions can I now raise that would not have made sense at the beginning of my paper? Questions for further research? Other ways that this topic could be approached?  
  • Are there other applications for my research? Could my questions be asked about different data in a different context? Could I use my methods to answer a different question?  
  • What action should be taken in light of this argument? What action do I predict will be taken or could lead to a solution?  
  • What larger context might my argument be a part of?  

What to avoid in your conclusion  

  • a complete restatement of all that you have said in your paper.  
  • a substantial counterargument that you do not have space to refute; you should introduce counterarguments before your conclusion.  
  • an apology for what you have not said. If you need to explain the scope of your paper, you should do this sooner—but don’t apologize for what you have not discussed in your paper.  
  • fake transitions like “in conclusion” that are followed by sentences that aren’t actually conclusions. (“In conclusion, I have now demonstrated that my thesis is correct.”)

How to Conclude an Essay | Interactive Example

Published on January 24, 2019 by Shona McCombes . Revised on July 23, 2023.

The conclusion is the final paragraph of your essay . A strong conclusion aims to:

  • Tie together the essay’s main points
  • Show why your argument matters
  • Leave the reader with a strong impression

Your conclusion should give a sense of closure and completion to your argument, but also show what new questions or possibilities it has opened up.

This conclusion is taken from our annotated essay example , which discusses the history of the Braille system. Hover over each part to see why it’s effective.

Braille paved the way for dramatic cultural changes in the way blind people were treated and the opportunities available to them. Louis Braille’s innovation was to reimagine existing reading systems from a blind perspective, and the success of this invention required sighted teachers to adapt to their students’ reality instead of the other way around. In this sense, Braille helped drive broader social changes in the status of blindness. New accessibility tools provide practical advantages to those who need them, but they can also change the perspectives and attitudes of those who do not.

To begin your conclusion, signal that the essay is coming to an end by returning to your overall argument.

Don’t just repeat your thesis statement —instead, try to rephrase your argument in a way that shows how it has been developed since the introduction.

Prevent plagiarism. Run a free check.

Next, remind the reader of the main points that you used to support your argument.

Avoid simply summarizing each paragraph or repeating each point in order; try to bring your points together in a way that makes the connections between them clear. The conclusion is your final chance to show how all the paragraphs of your essay add up to a coherent whole.

To wrap up your conclusion, zoom out to a broader view of the topic and consider the implications of your argument. For example:

  • Does it contribute a new understanding of your topic?
  • Does it raise new questions for future study?
  • Does it lead to practical suggestions or predictions?
  • Can it be applied to different contexts?
  • Can it be connected to a broader debate or theme?

Whatever your essay is about, the conclusion should aim to emphasize the significance of your argument, whether that’s within your academic subject or in the wider world.

Try to end with a strong, decisive sentence, leaving the reader with a lingering sense of interest in your topic.

The easiest way to improve your conclusion is to eliminate these common mistakes.

Don’t include new evidence

Any evidence or analysis that is essential to supporting your thesis statement should appear in the main body of the essay.

The conclusion might include minor pieces of new information—for example, a sentence or two discussing broader implications, or a quotation that nicely summarizes your central point. But it shouldn’t introduce any major new sources or ideas that need further explanation to understand.

Don’t use “concluding phrases”

Avoid using obvious stock phrases to tell the reader what you’re doing:

  • “In conclusion…”
  • “To sum up…”

These phrases aren’t forbidden, but they can make your writing sound weak. By returning to your main argument, it will quickly become clear that you are concluding the essay—you shouldn’t have to spell it out.

Don’t undermine your argument

Avoid using apologetic phrases that sound uncertain or confused:

  • “This is just one approach among many.”
  • “There are good arguments on both sides of this issue.”
  • “There is no clear answer to this problem.”

Even if your essay has explored different points of view, your own position should be clear. There may be many possible approaches to the topic, but you want to leave the reader convinced that yours is the best one!

This conclusion is taken from an argumentative essay about the internet’s impact on education. It acknowledges the opposing arguments while taking a clear, decisive position.

The internet has had a major positive impact on the world of education; occasional pitfalls aside, its value is evident in numerous applications. The future of teaching lies in the possibilities the internet opens up for communication, research, and interactivity. As the popularity of distance learning shows, students value the flexibility and accessibility offered by digital education, and educators should fully embrace these advantages. The internet’s dangers, real and imaginary, have been documented exhaustively by skeptics, but the internet is here to stay; it is time to focus seriously on its potential for good.

This conclusion is taken from a short expository essay that explains the invention of the printing press and its effects on European society. It focuses on giving a clear, concise overview of what was covered in the essay.

The invention of the printing press was important not only in terms of its immediate cultural and economic effects, but also in terms of its major impact on politics and religion across Europe. In the century following the invention of the printing press, the relatively stationary intellectual atmosphere of the Middle Ages gave way to the social upheavals of the Reformation and the Renaissance. A single technological innovation had contributed to the total reshaping of the continent.

This conclusion is taken from a literary analysis essay about Mary Shelley’s Frankenstein . It summarizes what the essay’s analysis achieved and emphasizes its originality.

By tracing the depiction of Frankenstein through the novel’s three volumes, I have demonstrated how the narrative structure shifts our perception of the character. While the Frankenstein of the first volume is depicted as having innocent intentions, the second and third volumes—first in the creature’s accusatory voice, and then in his own voice—increasingly undermine him, causing him to appear alternately ridiculous and vindictive. Far from the one-dimensional villain he is often taken to be, the character of Frankenstein is compelling because of the dynamic narrative frame in which he is placed. In this frame, Frankenstein’s narrative self-presentation responds to the images of him we see from others’ perspectives. This conclusion sheds new light on the novel, foregrounding Shelley’s unique layering of narrative perspectives and its importance for the depiction of character.

How to write a conclusion for a research paper

How to write a conclusion for a research paper

Research paper conclusions provide closure for your paper—but they can be difficult to write. What should you include? In this post, we discuss how to write a conclusion for a research paper.

What is a conclusion?

The conclusion to a research paper sums of your main argument and provides closure for your reader. It will return to your thesis statement and revisit the ways that you proved it.

The content and format of your conclusion will ultimately differ depending on the subject of your paper. Some fields have more specific expectations for what needs to be included.

You should always check your assignment’s guidelines or rubric to ensure that you understand what your instructor expects in a research paper conclusion.

How to write a conclusion

In this section, we break down the main parts of a conclusion and provide tips on how to approach each one.

The opening of a conclusion

The point of a conclusion’s opening statement is to transition from the main body of your paper to the concluding section. Some types of research papers include section headers that label each part of the paper. In these cases, your reader will be able to clearly see that you’re about to conclude.

In most other cases, begin your conclusion with a signal that indicates that you’re moving into the concluding section of your paper. For instance, you might start your conclusion by stating “in conclusion,” “to conclude,” or “in sum.”

What you can include in a conclusion

Although you shouldn’t include any new data or evidence in a conclusion, you can include suggestions for further research, insights about how your research could be applied in different contexts, or a course of action.

The bulk of the conclusion should synthesize—not summarize—the main points of your paper. If your introduction included historical information or an anecdote, return to that information now.

Your conclusion should also answer the “so what” question: why is this research relevant? Who should care about your argument and why?

The ending of a conclusion

Finally, you’ll want to end your conclusion with a closing statement that wraps up your concluding section (and your paper as a whole).

Tips for writing a conclusion

1. don’t include new data or evidence.

Your conclusion should provide closure to your paper, so introducing new information is not appropriate and will likely confuse your reader.

2. Don’t simply restate your thesis

You should never simply copy and paste your thesis statement into your conclusion. Instead, revisit your thesis in light of the evidence and analysis that you put forth in the main body of your paper.

3. Provide closure for your reader

A strong conclusion provides closure for the reader by synthesizing the main points of the paper and putting to rest any questions that the reader may have during the process of reading. The best way to test if your conclusion provides closure is to ask someone to read your paper.

4. Make suggestions for further research

While conclusions should not introduce new data or arguments, they can include suggestions for further research. A single research paper never covers everything—there are always possible new angles and approaches.

Next steps for a successful research paper

Once you’ve written your conclusion, you should review what you’ve written and make revisions, as needed. Then, double-check that you’ve cited all borrowed material and that your paper has a bibliography with accurate citations.

Use BibGuru’s citation generator to quickly create accurate citations for the books, articles, websites, and other sources that you used in your research paper.

Frequently Asked Questions about how to write a conclusion for a research paper

A conclusion contains an opening statement (often a restatement of the thesis), recommendations for further studies or applications, and a closing statement.

Start by signaling to the reader that you are moving into the concluding section.

The length of your conclusion will depend on the length of your paper. Most research paper conclusions will be around 1-2 paragraphs.

End your conclusion with a closing statement that wraps up the paper and provides closure to your reader.

Suggestions for Future Research

As researchers, it’s essential to recognize the limitations of our research and acknowledge the potential for future studies to build upon our findings. In this section, we will discuss possible future research directions and provide recommendations for further studies.

Discussion of Possible Future Research Directions

One direction for future research could be to investigate the impact of different variables on the research topic. For example, in a study on the effects of caffeine on mood, future research could explore the impact of age, gender, and caffeine intake on mood.

Another area for future research could be to examine the long-term effects of the research topic. For instance, a study on the effects of exercise on mental health could investigate the impact of exercise on mental health over an extended period.

Recommendations for Further Studies

Based on our research findings and limitations, we can suggest several areas for further studies. For example, further research could explore the impact of different interventions on the research topic. In a study on the effects of mindfulness on stress, future research could investigate the impact of different mindfulness interventions on stress levels.

Another recommendation for further studies could be to investigate the generalizability of the research findings. In a study conducted in a specific population, future research could explore the applicability of the findings to other populations.

By suggesting future research directions and providing recommendations for further studies, we can contribute to the growth of knowledge in our field and inspire other researchers to continue building upon our findings.

In conclusion, the conclusion of a research paper is just as important as its introduction. It’s your final chance to make a lasting impression on your reader and provide a clear understanding of your research’s significance.

To write an effective conclusion, you must summarize your main points, interpret your results, suggest future research, acknowledge limitations, and provide final thoughts. By adhering to these essential elements, you can ensure that your conclusion is well-crafted and leaves a lasting impression on your reader.

Remember, the conclusion is the final word on your research. Take the time to craft a thoughtful and well-written conclusion, and your readers will be sure to remember your research long after they’ve finished reading.

How to Write a Conclusion for a Research Paper

Sumalatha G

Table of Contents

Writing a conclusion for a research paper is a critical step that often determines the overall impact and impression the paper leaves on the reader. While some may view the conclusion as a mere formality, it is actually an opportunity to wrap up the main points, provide closure, and leave a lasting impression. In this article, we will explore the importance of a well-crafted conclusion and discuss various tips and strategies to help you write an engaging and impactful conclusion for your research paper.

Introduction

Before delving into the specifics of writing a conclusion, it is important to understand why it is such a crucial component of a research paper. The conclusion serves to summarize the main points of the paper and reemphasize their significance. A well-written conclusion can leave the reader satisfied and inspired, while a poorly executed one may undermine the credibility of the entire paper. Therefore, it is essential to give careful thought and attention to crafting an effective conclusion.

When writing a research paper, the conclusion acts as the final destination for the reader. It is the point where all the information, arguments, and evidence presented throughout the paper converge. Just as a traveler reaches the end of a journey, the reader reaches the conclusion to find closure and a sense of fulfillment. This is why the conclusion should not be taken lightly; it is a critical opportunity to leave a lasting impact on the reader.

Moreover, the conclusion is not merely a repetition of the introduction or a summary of the main points. It goes beyond that by providing a deeper understanding of the research findings and their implications. It allows the writer to reflect on the significance of their work and its potential contributions to the field. By doing so, the conclusion elevates the research paper from a mere collection of facts to a thought-provoking piece of scholarship.

In the following sections, we will explore various strategies and techniques for crafting a compelling conclusion. By understanding the importance of the conclusion and learning how to write one effectively, you will be equipped to create impactful research papers.

Structuring the Conclusion

In order to create an effective conclusion, it is important to consider its structure. A well-structured conclusion should begin by restating the thesis statement and summarizing the main points of the paper. It should then move on to provide a concise synthesis of the key findings and arguments, highlighting their implications and relevance. Finally, the conclusion should end with a thought-provoking statement that leaves the reader with a lasting impression.

Additionally, using phrases like "this research demonstrates," "the findings show," or "it is clear that" can help to highlight the significance of your research and emphasize your main conclusions.

Tips for Writing an Engaging Conclusion

Writing an engaging conclusion requires careful consideration and attention to detail. Here are some tips to help you create an impactful conclusion for your research paper:

  • Revisit the Introduction: Start your conclusion by referencing your introduction. Remind the reader of the research question or problem you initially posed and show how your research has addressed it.
  • Summarize Your Main Points: Provide a concise summary of the main points and arguments presented in your paper. Be sure to restate your thesis statement and highlight the key findings.
  • Offer a Fresh Perspective: Use the conclusion as an opportunity to provide a fresh perspective or offer insights that go beyond the main body of the paper. This will leave the reader with something new to consider.
  • Leave a Lasting Impression: End your conclusion with a thought-provoking statement or a call to action. This will leave a lasting impression on the reader and encourage further exploration of the research topic.

Addressing Counter Arguments In Conclusion

While crafting your conclusion, you can address any potential counterarguments or limitations of your research. This will demonstrate that you have considered alternative perspectives and have taken them into account in your conclusions. By acknowledging potential counterarguments, you can strengthen the credibility and validity of your research. And by openly discussing limitations, you demonstrate transparency and honesty in your research process.

Language and Tone To Be Used In Conclusion

The language and tone of your conclusion play a crucial role in shaping the overall impression of your research paper. It is important to use clear and concise language that is appropriate for the academic context. Avoid using overly informal or colloquial language that may undermine the credibility of your research. Additionally, consider the tone of your conclusion – it should be professional, confident, and persuasive, while still maintaining a respectful and objective tone.

When it comes to the language used in your conclusion, precision is key. You want to ensure that your ideas are communicated effectively and that there is no room for misinterpretation. Using clear and concise language will not only make your conclusion easier to understand but will also demonstrate your command of the subject matter.

Furthermore, it is important to strike the right balance between formality and accessibility. While academic writing typically requires a more formal tone, you should still aim to make your conclusion accessible to a wider audience. This means avoiding jargon or technical terms that may confuse readers who are not familiar with the subject matter. Instead, opt for language that is clear and straightforward, allowing anyone to grasp the main points of your research.

Another aspect to consider is the tone of your conclusion. The tone should reflect the confidence you have in your research findings and the strength of your argument. By adopting a professional and confident tone, you are more likely to convince your readers of the validity and importance of your research. However, it is crucial to strike a balance and avoid sounding arrogant or dismissive of opposing viewpoints. Maintaining a respectful and objective tone will help you engage with your audience in a more persuasive manner.

Moreover, the tone of your conclusion should align with the overall tone of your research paper. Consistency in tone throughout your paper will create a cohesive and unified piece of writing.

Common Mistakes to Avoid While Writing a Conclusion

When writing a conclusion, there are several common mistakes that researchers often make. By being aware of these pitfalls, you can avoid them and create a more effective conclusion for your research paper. Some common mistakes include:

  • Repeating the Introduction: A conclusion should not simply be a reworded version of the introduction. While it is important to revisit the main points, try to present them in a fresh and broader perspective, by foregrounding the implications/impacts of your research.
  • Introducing New Information: The conclusion should not introduce any new information or arguments. Instead, it should focus on summarizing and synthesizing the main points presented in the paper.
  • Being Vague or General: Avoid using vague or general statements in your conclusion. Instead, be specific and provide concrete examples or evidence to support your main points.
  • Ending Abruptly: A conclusion should provide a sense of closure and completeness. Avoid ending your conclusion abruptly or leaving the reader with unanswered questions.

Editing and Revising the Conclusion

Just like the rest of your research paper, the conclusion should go through a thorough editing and revising process. This will help to ensure clarity, coherence, and impact in the conclusion. As you revise your conclusion, consider the following:

  • Check for Consistency: Ensure that your conclusion aligns with the main body of the paper and does not introduce any new or contradictory information.
  • Eliminate Redundancy: Remove any repetitive or redundant information in your conclusion. Instead, focus on presenting the key points in a concise and engaging manner.
  • Proofread for Clarity: Read your conclusion aloud or ask someone else to read it to ensure that it is clear and understandable. Check for any grammatical or spelling errors that may distract the reader.
  • Seek Feedback: Consider sharing your conclusion with peers or mentors to get their feedback and insights. This can help you strengthen your conclusion and make it more impactful.

How to Write Conclusion as a Call to Action

Finally, consider using your conclusion as a call to action. Encourage the reader to take further action, such as conducting additional research or considering the implications of your findings. By providing a clear call to action, you can inspire the reader to actively engage with your research and continue the conversation on the topic.

Adapting to Different Research Paper Types

It is important to adapt your conclusion approach based on the type of research paper you are writing. Different research paper types may require different strategies and approaches to writing the conclusion. For example, a scientific research paper may focus more on summarizing the key findings and implications, while a persuasive research paper may emphasize the call to action and the potential impact of the research. Tailor your conclusion to suit the specific goals and requirements of your research paper.

Final Thoughts

A well-crafted conclusion can leave a lasting impression on the reader and enhance the impact of your research. By following the tips and strategies outlined in this article, you can create an engaging and impactful conclusion that effectively summarizes your main points, addresses potential counterarguments, and leaves the reader with a sense of closure and inspiration. Embrace the importance of the conclusion and view it as an opportunity to showcase the significance and relevance of your research.

How to Write a Research Paper Conclusion Section

how to conclude research paper

What is a conclusion in a research paper?

The conclusion in a research paper is the final paragraph or two in a research paper. In scientific papers, the conclusion usually follows the Discussion section , summarizing the importance of the findings and reminding the reader why the work presented in the paper is relevant.

However, it can be a bit confusing to distinguish the conclusion section/paragraph from a summary or a repetition of your findings, your own opinion, or the statement of the implications of your work. In fact, the conclusion should contain a bit of all of these other parts but go beyond it—but not too far beyond! 

The structure and content of the conclusion section can also vary depending on whether you are writing a research manuscript or an essay. This article will explain how to write a good conclusion section, what exactly it should (and should not) contain, how it should be structured, and what you should avoid when writing it.  

Table of Contents:

What does a good conclusion section do, what to include in a research paper conclusion.

  • Conclusion in an Essay
  • Research Paper Conclusion 
  • Conclusion Paragraph Outline and Example
  • What Not to Do When Writing a Conclusion

The conclusion of a research paper has several key objectives. It should:

  • Restate your research problem addressed in the introduction section
  • Summarize your main arguments, important findings, and broader implications
  • Synthesize key takeaways from your study

The specific content in the conclusion depends on whether your paper presents the results of original scientific research or constructs an argument through engagement with previously published sources.

You presented your general field of study to the reader in the introduction section, by moving from general information (the background of your work, often combined with a literature review ) to the rationale of your study and then to the specific problem or topic you addressed, formulated in the form of the statement of the problem in research or the thesis statement in an essay.

In the conclusion section, in contrast, your task is to move from your specific findings or arguments back to a more general depiction of how your research contributes to the readers’ understanding of a certain concept or helps solve a practical problem, or fills an important gap in the literature. The content of your conclusion section depends on the type of research you are doing and what type of paper you are writing. But whatever the outcome of your work is, the conclusion is where you briefly summarize it and place it within a larger context. It could be called the “take-home message” of the entire paper.

What to summarize in the conclusion

Your conclusion section needs to contain a very brief summary of your work , a very brief summary of the main findings of your work, and a mention of anything else that seems relevant when you now look at your work from a bigger perspective, even if it was not initially listed as one of your main research questions. This could be a limitation, for example, a problem with the design of your experiment that either needs to be considered when drawing any conclusions or that led you to ask a different question and therefore draw different conclusions at the end of your study (compared to when you started out).

Once you have reminded the reader of what you did and what you found, you need to go beyond that and also provide either your own opinion on why your work is relevant (and for whom, and how) or theoretical or practical implications of the study , or make a specific call for action if there is one to be made.   

How to Write an Essay Conclusion

Academic essays follow quite different structures than their counterparts in STEM and the natural sciences. Humanities papers often have conclusion sections that are much longer and contain more detail than scientific papers. There are three main types of academic essay conclusions.

Summarizing conclusion

The most typical conclusion at the end of an analytical/explanatory/argumentative essay is a summarizing conclusion . This is, as the name suggests, a clear summary of the main points of your topic and thesis. Since you might have gone through a number of different arguments or subtopics in the main part of your essay, you need to remind the reader again what those were, how they fit into each other, and how they helped you develop or corroborate your hypothesis.

For an essay that analyzes how recruiters can hire the best candidates in the shortest time or on “how starving yourself will increase your lifespan, according to science”, a summary of all the points you discussed might be all you need. Note that you should not exactly repeat what you said earlier, but rather highlight the essential details and present those to your reader in a different way. 

Externalizing conclusion

If you think that just reminding the reader of your main points is not enough, you can opt for an externalizing conclusion instead, that presents new points that were not presented in the paper so far. These new points can be additional facts and information or they can be ideas that are relevant to the topic and have not been mentioned before.

Such a conclusion can stimulate your readers to think about your topic or the implications of your analysis in a whole new way. For example, at the end of a historical analysis of a specific event or development, you could direct your reader’s attention to some current events that were not the topic of your essay but that provide a different context for your findings.

Editorial conclusion

In an editorial conclusion , another common type of conclusion that you will find at the end of papers and essays, you do not add new information but instead present your own experiences or opinions on the topic to round everything up. What makes this type of conclusion interesting is that you can choose to agree or disagree with the information you presented in your paper so far. For example, if you have collected and analyzed information on how a specific diet helps people lose weight, you can nevertheless have your doubts on the sustainability of that diet or its practicability in real life—if such arguments were not included in your original thesis and have therefore not been covered in the main part of your paper, the conclusion section is the place where you can get your opinion across.    

How to Conclude an Empirical Research Paper

An empirical research paper is usually more concise and succinct than an essay, because, if it is written well, it focuses on one specific question, describes the method that was used to answer that one question, describes and explains the results, and guides the reader in a logical way from the introduction to the discussion without going on tangents or digging into not absolutely relevant topics.

Summarize the findings

In a scientific paper, you should include a summary of the findings. Don’t go into great detail here (you will have presented your in-depth  results  and  discussion  already), but do clearly express the answers to the  research questions  you investigated.

Describe your main findings, even if they weren’t necessarily the ones anticipated, and explain the conclusion they led you to. Explain these findings in as few words as possible.

Instead of beginning with “ In conclusion, in this study, we investigated the effect of stress on the brain using fMRI …”, you should try to find a way to incorporate the repetition of the essential (and only the essential) details into the summary of the key points. “ The findings of this fMRI study on the effect of stress on the brain suggest that …” or “ While it has been known for a long time that stress has an effect on the brain, the findings of this fMRI study show that, surprisingly… ” would be better ways to start a conclusion. 

You should also not bring up new ideas or present new facts in the conclusion of a research paper, but stick to the background information you have presented earlier, to the findings you have already discussed, and the limitations and implications you have already described. The one thing you can add here is a practical recommendation that you haven’t clearly stated before—but even that one needs to follow logically from everything you have already discussed in the discussion section.

Discuss the implications

After summing up your key arguments or findings, conclude the paper by stating the broader implications of the research , whether in methods , approach, or findings. Express practical or theoretical takeaways from your paper. This often looks like a “call to action” or a final “sales pitch” that puts an exclamation point on your paper.

If your research topic is more theoretical in nature, your closing statement should express the significance of your argument—for example, in proposing a new understanding of a topic or laying the groundwork for future research.

Future research example

Future research into education standards should focus on establishing a more detailed picture of how novel pedagogical approaches impact young people’s ability to absorb new and difficult concepts. Moreover, observational studies are needed to gain more insight into how specific teaching models affect the retention of relationships and facts—for instance, how inquiry-based learning and its emphasis on lateral thinking can be used as a jumping-off point for more holistic classroom approaches.

Research Conclusion Example and Outline

Let’s revisit the study on the effect of stress on the brain we mentioned before and see what the common structure for a conclusion paragraph looks like, in three steps. Following these simple steps will make it easy for you to wrap everything up in one short paragraph that contains all the essential information: 

One: Short summary of what you did, but integrated into the summary of your findings:

While it has been known for a long time that stress has an effect on the brain, the findings of this fMRI study in 25 university students going through mid-term exams show that, surprisingly, one’s attitude to the experienced stress significantly modulates the brain’s response to it. 

Note that you don’t need to repeat any methodological or technical details here—the reader has been presented with all of these before, they have read your results section and the discussion of your results, and even (hopefully!) a discussion of the limitations and strengths of your paper. The only thing you need to remind them of here is the essential outcome of your work. 

Two: Add implications, and don’t forget to specify who this might be relevant for: 

Students could be considered a specific subsample of the general population, but earlier research shows that the effect that exam stress has on their physical and mental health is comparable to the effects of other types of stress on individuals of other ages and occupations. Further research into practical ways of modulating not only one’s mental stress response but potentially also one’s brain activity (e.g., via neurofeedback training) are warranted.

This is a “research implication”, and it is nicely combined with a mention of a potential limitation of the study (the student sample) that turns out not to be a limitation after all (because earlier research suggests we can generalize to other populations). If there already is a lot of research on neurofeedback for stress control, by the way, then this should have been discussed in your discussion section earlier and you wouldn’t say such studies are “warranted” here but rather specify how your findings could inspire specific future experiments or how they should be implemented in existing applications. 

Three: The most important thing is that your conclusion paragraph accurately reflects the content of your paper. Compare it to your research paper title , your research paper abstract , and to your journal submission cover letter , in case you already have one—if these do not all tell the same story, then you need to go back to your paper, start again from the introduction section, and find out where you lost the logical thread. As always, consistency is key.    

Problems to Avoid When Writing a Conclusion 

  • Do not suddenly introduce new information that has never been mentioned before (unless you are writing an essay and opting for an externalizing conclusion, see above). The conclusion section is not where you want to surprise your readers, but the take-home message of what you have already presented.
  • Do not simply copy your abstract, the conclusion section of your abstract, or the first sentence of your introduction, and put it at the end of the discussion section. Even if these parts of your paper cover the same points, they should not be identical.
  • Do not start the conclusion with “In conclusion”. If it has its own section heading, that is redundant, and if it is the last paragraph of the discussion section, it is inelegant and also not really necessary. The reader expects you to wrap your work up in the last paragraph, so you don’t have to announce that. Just look at the above example to see how to start a conclusion in a natural way.
  • Do not forget what your research objectives were and how you initially formulated the statement of the problem in your introduction section. If your story/approach/conclusions changed because of methodological issues or information you were not aware of when you started, then make sure you go back to the beginning and adapt your entire story (not just the ending).

Finishing a research paper feels great, but getting to the end—especially the conclusion—can be a bit tricky. 

People often wonder, "How do I wrap up my findings nicely?" or "What tone should I use in the conclusion?" 

If you're dealing with these questions, you're not alone! Many researchers find writing a good conclusion a bit challenging since it's a crucial part that is meant to leave a strong impression on your readers.

No need to worry! 

In this guide, we'll show you how to write a conclusion that not only ties up your research paper neatly but also leaves a strong impression. We'll cover everything from summarizing effectively to creating the right feeling. 

So, let’s get started. 

On This Page On This Page -->

What is a Research Paper Conclusion?

A research paper conclusion is like the final chapter of your paper. It's where you bring everything together and leave a lasting impression on your readers. 

In simple terms, it's the last part where you sum up what you found during your research and explain why it matters. 

The conclusion isn't just a summary; it's a chance to make your research memorable and show its importance.

Types of Research Paper Conclusions

When it comes to writing the conclusion of your research paper, there isn't a one-size-fits-all approach. Different types of research papers call for different types of conclusions. Here are some common types:

  • Summarizing Conclusion

This type recaps the key points and findings of your research. It's like giving your readers a quick overview of what you discovered without introducing new information. Summarizing conclusions works well for straightforward research papers.

  • Reflective Conclusion

A reflective conclusion allows you to share your personal thoughts on the research process, challenges faced, and lessons learned. It adds a human touch to your paper, giving readers insight into your journey as a researcher.

  • Open-ended Conclusion

Some research papers benefit from an open-ended conclusion that leaves room for further exploration. This type invites readers to think critically, ask questions, or even conduct additional research on the same topic.

How to Write a Research Paper Conclusion: 7 Steps

Writing an effective conclusion for your research paper involves more than just summarizing your findings. Follow these six essential steps to ensure your conclusion leaves a lasting impact:

Step 1: Restate the Research Problem

Start wrapping up your paper by going back to the main research question or issue you were investigating. 

Remind your readers about what you were trying to find out or understand. This gives your conclusion a clear connection to the original goal of your research, helping readers see the bigger picture.

Step 2: Revisit Your Thesis Statement

Go back to the main idea or argument you had in your paper—this is called your thesis statement. Double-check that your conclusion matches and supports what you wanted to prove or talk about in the beginning. 

This step is important because it keeps your conclusion connected to the main point of your research, making everything fit together nicely.

Step 3: Summarize Key Points

Give a short and clear recap of the most important things you found in your research. Keep it simple and stick to what you've already talked about—don't bring in new details now. 

The goal is to remind your readers of the important stuff you covered earlier. This helps to underline why your research is important and what you want them to take away from it.

Step 4: Discuss the Implications

Address the broader implications of your research. Explain why your findings matter and how they contribute to the existing body of knowledge in your field. 

Discuss the practical applications of your research and highlight any potential areas for further exploration.

Step 5: Connect with the Introduction

Create a seamless connection between your conclusion and the introduction. Referencing key elements from the introduction helps to create a cohesive narrative for your paper. 

This connection gives your research a sense of completeness and unity.

Step 6: Consider the "So What?" Factor

Ask yourself the question, "So what?" Why should readers care about your research? Clearly articulate the significance of your findings and their relevance to the broader academic or real-world context. 

Demonstrating the impact of your research adds depth to your conclusion.

Step 7: End with a Strong Closing Statement:

Conclude your research paper with a memorable closing statement. This could be a thought-provoking reflection, a call to action, or a suggestion for future research.

A strong closing leaves a lasting impression on your readers and emphasizes the importance of your work.

Research Paper Conclusion Examples

When it comes to writing a conclusion for your research paper, examining examples can offer valuable insights. Let’s take a look at this comprehensive example given below:

Things to Avoid While Writing the Research Paper Conclusion

While crafting a conclusion for your research paper, it's crucial to steer clear of common pitfalls that can diminish the impact of your final remarks. 

Here are some things to avoid:

  • Repetition: Avoid rehashing the exact language used in the introduction or body of your paper. A conclusion should summarize key points without duplicating content.
  • Introducing New Information: Resist the temptation to introduce new ideas or data in the conclusion. This section is for summarizing existing content and reinforcing key findings.
  • Overly Complex Language: Keep your conclusion clear and accessible. Avoid introducing overly complex or technical language that might confuse your readers.
  • Lack of Connection to Introduction: Ensure that your conclusion ties back to the introduction. Failing to connect these sections can make your paper feel disjointed.
  • Vague Statements: Steer clear of vague statements that lack substance. Clearly articulate the significance of your findings and their broader implications.
  • Apologies or Excuses: Avoid including apologies or excuses for limitations in your research. While acknowledging limitations is important, the conclusion is not the place to dwell on them.
  • New Arguments or Debates: The conclusion is not the space to introduce new debates or arguments. Keep the focus on summarizing your research and its implications.
  • Abrupt Endings: A conclusion should not end abruptly. Instead, provide a thoughtful and well-rounded closing statement about the results of your study.

To sum it up, we've gone through important steps to make your research paper conclusion strong. We covered things like going back to your main question, talking about the most important points, and thinking about why your research matters in the real world.

Remember, a good ending is more than just a summary; it captures the heart of your research and answers the big "So what?" question. 

Remember, don't say the same things too much, don't add new details at the end, and keep your language simple!

How to Write a Conclusion for a Research Paper

Do you ever feel like you’re inside a black hole when it comes time to write your research paper conclusion? You’ve spent weeks (or months!) gathering reliable sources and supporting evidence, but now that the big moment has come, you don’t know how to sum up all of your hard work! But fear not: even though reaching an effective conclusion for a research paper can seem daunting at times, with a few tips and tricks from experts in the field, anyone can learn how to master this crucial writing skill. In this blog post, we’ll talk about some of the most successful strategies for crafting an impressive conclusion for your next masterpiece.

Summarize the main points of your research paper

One of the most important parts of research writing is the conclusion, as it acts as not only a summary of not only your research paper but also a representation of your overall writing ability. Crafting an effective research paper conclusion requires careful consideration of the research evidence and an ability to identify themes and draw connections between these themes. Fortunately, there are several tips to help writers in their journey to composing an effective research paper conclusion. From making sure the conclusion connects to the introduction to summarizing research findings in new and creative ways, following a few simple steps can ensure that writers finish their research papers with confidence.

Identify any unresolved questions or issues in the paper

Finishing up a research paper can often be the hardest part, leading to advice such as “write the conclusion last.” Unaddressed questions and issues within the paper present an additional challenge when writing the closing remarks. Careful consideration of how to end a research paper should include an honest assessment of what remains unresolved after studying the topic. Addressing any remaining questions or issues will not only ensure closure on your research paper; it also has lasting benefits by providing advice for future studies on similar topics.

Offer a solution or suggestion for future research

To successfully conclude a research paper, it is important to apply certain tricks and advice from experts. Future research should focus on understanding the ways in which a good conclusion can be written so as to add value to the overall paper. Discussions could focus on elements that are generally valued in concluding paragraphs, such as summarizing key findings and implications of the study, validating the research problem statement, and linking back to previously presented evidence. With this kind of insight into concluding statements, researchers would have better chances of producing worthwhile scholarly contributions .

Reflect on the overall implications of your findings

After completing the research process and coming to a conclusion, it is important to reflect on its overall implication. When it comes to how to end a research paper, one must think about what the conclusion implies for future endeavors and application of knowledge. Reflecting on implications can create questions for further research opportunities or exalt original interpretations from the conclusion. Writing with this in mind allows conclusion statements that truly encapsulate the importance of research outcomes.

Restate the thesis in different terms

Writing a strong conclusion for your research paper can be tricky, but there are tips and tricks that can help. One great technique is to restate the thesis in different terms. Doing so allows you to emphasize the main points of your paper and tie them all together into one appealing conclusion. Additionally, it needs to follow from the content covered throughout the body of your essay and connect it with other information presented at the beginning or throughout the paper. With some clever word choices and rhetorical devices, you have the potential to create an effective ending that will leave your reader with a lasting impression.

End with a call to action for readers to take away from your work

As concluding a research paper can be challenging, it is important to reiterate the main ideas and provide an actionable call to conclusion. While providing advice to readers is a great way to tie up loose ends in any research paper, one must also think carefully about what advice they provide. Offer up a course of action that pushes forward your thesis while remaining conscious of the limitations and complexities behind your work. An effective concluding statement speaks on behalf of both those researching and reading, leaving a lasting impression without unintentionally oversimplifying the material.

How to Write a Conclusion for a Research Paper that Resonates

blog image

The conclusion of a research paper is a crucial part of the entire document. The final section summarizes the main points, restates the thesis statement, and provides closure to the reader. Writing a strong conclusion for a research paper can be challenging because you must bring together all the ideas you’ve presented concisely and compellingly. Don’t fret, as we’ll let you know how to write a conclusion for a research paper like a professional  paper writing service  provider. So, let’s dive in!

Table of Contents

The Ultimate Guide on How to Write a Conclusion for a Research Paper

A great conclusion makes your paper stand out and leaves a lasting impression on your readers. Let us help you figure out how to write a killer conclusion for your research paper.

Four Important Elements of a Research Paper Conclusion

These are the essential elements you must include in the conclusion of your  research paper writing  for a lasting impression.

Restate the Thesis Statement

It’s really important to remind readers of the main argument in your paper. You should state the  thesis statement  in the intro and then again in the conclusion. But don’t just copy and paste the same words! It’s better to rephrase it in a slightly different way so readers know you understand the topic.

Summarize the Main Points of the Research Paper

It’s important to sum up the paper’s main points to show the reader it’s covered the topic well. Just use the topic sentences from the body paragraphs and make it brief; that should do it.

Discuss the Implications of the Research

It’s important to cover the implications of the research so the reader can understand the bigger picture. This part should emphasize the real-world or theoretical implications of the research and explain why the results are important. These implications can involve multiple topics, such as policy, practices, theories, or further research.

Provide Closure to the Reader

A satisfying research paper conclusion is the key to its success. This last section should link together the main points made throughout the paper and make the reader feel like the paper has come to its natural conclusion. It’s a great idea to finish the conclusion with a thought-provoking statement, an invitation to take action or a question that will leave the reader pondering.

For Example:

Tips for Writing A Strong Conclusion

These are the expert tips to help you write a strong conclusion for your research paper:

Tip 1: Keep it Concise and to The Point

Make sure your conclusion is short and sweet, summing up the main points of your research paper without adding anything new. Don’t use different words or phrases to fill up space – say what needs to be said in a simple, straightforward way.

Tip 2: Use language that is clear and easy to understand

Make sure everyone easily understands your conclusion. Don’t use technical words. Stick to the main points and make sure everyone can follow along.

Tip 3: Avoid Introducing New Information

Your conclusion should wrap up the ideas you’ve presented in your paper, not add anything new. Summarize the main ideas and arguments that you’ve presented and show how they back up your thesis.

Tip 4: Use a Strong Concluding Sentence

Wrapping up your paper with a strong conclusion helps tie everything together and leaves an impact on the reader. Why not finish with a thought-provoking question, a call to action or a powerful statement? It’ll be sure to stick with them.

Common Mistakes to Avoid

Here are some common mistakes you should avoid when writing a conclusion for your research paper:

Don’t Repeat the Information

In your research paper conclusion, try not to copy what’s already been said in the body of the paper. Sum up the main points, but don’t just repeat them word for word. Show how the evidence and ideas in the paper back up the thesis.

Avoid Including Personal Opinions and or Biases

Be careful not to let your feelings sneak into the conclusion. Stick to the facts and sum up the main points of your paper instead of giving your own opinion. Keep it objective!

Don’t Use Weak Language or Cliches:

Don’t use weak language or cliches like “in conclusion” or “it can be said that.” Also, don’t say “more research is needed” since it makes your conclusion seem unfulfilled. Instead, be clear about when and where you’re talking about and emphasize the importance of your research.

Example of Good Research Paper Conclusions

It’s important to make a lasting impression on your reader, so having a good conclusion to your research paper is key. Here are some examples of what makes a strong conclusion and the elements that make it effective:

Example 1 – A Research Paper on The Effects of Social Media on Mental Health:

Through the research analysis, it is clear that social media use can significantly negatively affect mental health. To address this issue, individuals and society need to recognize social media’s impact and take steps to mitigate its negative effects. This research highlights the need for further investigation into the relationship between social media and mental health, as well as the development of strategies to promote healthy social media use.

Example 2 – A Research Paper on The Benefits of Exercise:

The findings of this study demonstrate the numerous benefits of regular exercise, including improved cardiovascular health, increased strength, and reduced stress levels. These benefits highlight the importance of physical activity for individuals of all ages and abilities. Individuals and society need to prioritize exercise and promote physical activity to improve overall health and well-being.

Finishing your research paper with a strong conclusion is key to leaving a lasting impact on your reader. We are summarizing the conclusion for a research paper in brief points.

  •  Sum up the main points of your paper and restate your thesis statement.
  • Think about the implications of your research and provide closure for your reader.
  • Keep your language clear and avoid introducing new info.
  • Use a strong conclusion sentence, and don’t make mistakes like repeating yourself or adding personal opinions or bias.

Hopefully you won’t need to search how to write conclusion in research again. Still, if you need help with a conclusion in research paper, you can order today so  our writers  can assist you immediately.

Can Describing Study Limitations Improve the Quality of Your Paper? This Section Could Be More Important Than You Think!

  • 3 minute read

Table of Contents

Every study has its limitations, whether inherent to the sample chosen or the methods employed. However, researchers frequently encounter challenges in effectively articulating the limitations of their studies 1 . While the practice may seem counterproductive, communicating the limitations of a study can help inform the audience of the robustness of the findings and conclusions. Presenting the limitations effectively is a great way to communicate the study’s credibility to readers.

In this article, we will discuss why it is advisable to clearly articulate the limitations of a study and how one can go about this task.

Why You Must Describe Study Limitations Comprehensively

Prevent criticism.

Thoroughly stating the limitations of your study reduces the risk of future external discoveries, safeguarding your credibility as a researcher 2 .

Show understanding

When you comprehensively list study limitations, you demonstrate a clear understanding of the study’s goals, leaving a positive impression on reviewers and readers and highlighting your expertise in the subject area 2 .

Suggest improvements

Describing limitations invites suggestions for improvement, enhancing study design for more robust findings and further advancing your field of research 2 .

Things to Keep in Mind While Writing Limitations

Identify the type(s) of limitation clearly.

Clearly state where in your study the limitations exist and identify the source of these limitations 3 . They may arise from study design, sampling, data collection, data analysis, or interpretation.

Limitation in study design:

“This study assessed psychological wellbeing post-hospitalization via online interviews, acknowledging potential downsides compared to in-person interviews.”

Limitation in sampling:

“Our sampling focused on urban areas, possibly overlooking valuable insights from rural populations, which could offer differing perspectives on the studied phenomenon.”

Limitation in data collection:

“A significantly higher number of insects were collected from quadrant four of the nature reserve, which may have introduced geographical biases in the data.”

Limitation in data analysis:

“Our multi factor analysis did not explore the relationship between education level of parents and individual net worth, although the factors might be related.”

Limitation in study results:

“Since our study looked at deterioration of steel implants cross-sectionally, longitudinal studies are required to confirm our findings.”

Explain their impact on study findings

Addressing limitations explains their impact on the findings, showcasing scientific rigor, and revealing broader implications.

“We used vehicle count and passenger capacity as proxies for commuters on Beijing’s national highway, which could have resulted in an overestimate of nearly 20–40%. This implies that more people could have stayed at home during holidays than our results suggest.”

Detail steps to minimize impact

Explain any action taken to lessen the impact of limitations 3 .

“Protein analysis of plant metabolites was performed in the field at suboptimal conditions. However, we used triplicates across samples to reduce any error.”

Suggest future avoidance strategies

Suggest ways to prevent the limitations in future studies 3 . As mentioned earlier, this can be a valuable contribution to your field of research and accelerate its growth.

“Our analysis reveals inaccuracies with mid-range LIDAR at 1000 m altitude. We recommend that future aerial surveys use mid-range LIDARs at 800 m or lower for improved accuracy.”

Researchers may hesitate to discuss the limitations of their study when writing a manuscript, thinking it may hinder journal acceptance chances or assuming that the reviewers and editors will handle this aspect. However, this cannot be farther from the truth. Clearly stating limitations improves your manuscript’s publication odds and establishes professional credibility in the long run.

Background: Allergic rhinitis (AR) is a chronic disease, and several risk factors predispose individuals to the condition in their daily lives, including exposure to allergens and inhalation irritants. Analyzing the potential risk factors that can trigger AR can provide reference material for individuals to use to reduce its occurrence in their daily lives. Nowadays, social media is a part of daily life, with an increasing number of people using at least 1 platform regularly. Social media enables users to share experiences among large groups of people who share the same interests and experience the same afflictions. Notably, these channels promote the ability to share health information.

Objective: This study aims to construct an intelligent method (TopicS-ClusterREV) for identifying the risk factors of AR based on these social media comments. The main questions were as follows: How many comments contained AR risk factor information? How many categories can these risk factors be summarized into? How do these risk factors trigger AR?

Methods: This study crawled all the data from May 2012 to May 2022 under the topic of allergic rhinitis on Zhihu, obtaining a total of 9628 posts and 33,747 comments. We improved the Skip-gram model to train topic-enhanced word vector representations (TopicS) and then vectorized annotated text items for training the risk factor classifier. Furthermore, cluster analysis enabled a closer look into the opinions expressed in the category, namely gaining insight into how risk factors trigger AR.

Results: Our classifier identified more comments containing risk factors than the other classification models, with an accuracy rate of 96.1% and a recall rate of 96.3%. In general, we clustered texts containing risk factors into 28 categories, with season, region, and mites being the most common risk factors. We gained insight into the risk factors expressed in each category; for example, seasonal changes and increased temperature differences between day and night can disrupt the body’s immune system and lead to the development of allergies.

Conclusions: Our approach can handle the amount of data and extract risk factors effectively. Moreover, the summary of risk factors can serve as a reference for individuals to reduce AR in their daily lives. The experimental data also provide a potential pathway that triggers AR. This finding can guide the development of management plans and interventions for AR.

Introduction

Over the past few decades, the prevalence of chronic diseases has increased significantly, becoming a global public health concern. The World Health Organization has listed allergic diseases as one of the disease types that require priority research and prevention in the 21st century [ 1 ]. As a common chronic disease, allergic rhinitis (AR) is a multifactorial disease that is induced by environmental conditions or certain genes [ 2 ]. AR not only has a significant impact on individuals’ sleep, social life, and work attendance but also triggers comorbidities such as conjunctivitis, atopic dermatitis, and asthma [ 3 ]. Large-scale flow survey data showed that AR currently affects several people in China alone [ 4 ] and with an estimated prevalence between 15% and 20% worldwide [ 5 ]. The direct and indirect costs associated with the management of AR are also a significant burden on society. For instance, the total cost of AR in Sweden, with a population of 9.5 million, was estimated at €1.3 (US $1.41) billion annually [ 6 ]. These unexpectedly high costs could be related to the high prevalence of disease, in combination with the previously often underestimated indirect costs that arise from reduced work efficiency and absenteeism and the potential costs associated with treating AR comorbidities [ 6 ].

Currently, there is no cure for AR, and individuals need to avoid the disease risk factors such as exposure to allergens and inhalation irritants [ 7 ] during the long self-management process. Therefore, identifying AR risk factors can provide a reference for patients to help reduce the condition in their daily lives [ 8 ].

A plethora of studies have been proposed to identify AR risk factors. These studies recruited participants with symptoms of AR and control participants without AR symptoms from a specific age group or a particular geographical area. These studies collected demographic information, lifestyle habits, family history, comorbidities, and residential areas through questionnaires. Subsequently, they used correlation methods to explore the relationship between these data and AR, aiming to identify the risk factors for AR within the specified age group or geographical area [ 9 ]. However, these studies have 2 limitations. First, these studies specifically target certain age groups or geographical areas, and questionnaires can only gather data on specific pieces of information. Owing to the constraints of questionnaire surveys, it is challenging to identify potential risk factors that may be present in individuals’ daily lives. As a result, the risk factors identified through survey-based studies have a limited scope and are incomplete. As such, they provide limited insights for a broader patient population. Second, the survey-based approach demands a commitment to long-term investigation and a substantial effort to collect representative responses [ 10 ]. In contrast, collecting information from social media platforms can cover large geographical areas at a comparatively low cost [ 10 ]. Social media platforms allow users to share experiences and opinions on various topics [ 11 , 12 ], including personal health issues [ 13 ]. Over time, highly unstructured and implicit knowledge has been generated in communities where users frequently participate [ 14 , 15 ], which can provide daily health records that are difficult to obtain from traditional questionnaire surveys. Therefore, social media can become a potential source of information for identifying risk factors for diseases such as AR [ 16 ].

Text-mining techniques are an effective tool for using voluminous social media data [ 17 ]. Some studies have combined social media data analysis to obtain knowledge about disease risk factors [ 18 , 19 ]. However, the abovementioned studies on disease risk factors used only shallow text features such as the number of social media text items and word cooccurrences, which are not conducive to identifying disease risk factors in the context of colloquial and diverse user expressions [ 20 ]. In this study, we designed a text-processing framework to automatically identify risk factors from social media data [ 21 ]. We used social media comments to construct a natural language processing–based AR risk factor identification method, aiming to tackle the problems of omission and low accuracy in traditional disease-related information identification methods that rely solely on shallow text features such as word frequency.

To be more specific, we developed an AR risk factor identification method that integrates pretrained word embeddings with text convolutional neural networks (CNNs). The Word2vec algorithm has proven to be superior in text vector representation [ 20 ]. This is a prediction-based approach that predicts the neighboring words that are most likely to appear within a window size around a center word in a corpus, resulting in high-dimensional vector representations that capture semantic aggregation. As social media users may mention related topics, such as symptoms and treatments, when describing risk factors in their comments, we used a local context window to achieve better semantic aggregation of AR risk factors, a method that has been demonstrated to be effective for such aggregation. In addition, using the Skip-gram model to train word pairs enables the incorporation of word thematic information, thus improving attention to risk factor phrases. The convolutional network can convolve the text in the word vector dimension and extract critical information through the max-pooling layer operation. In addition, this study used a clustering method with review mechanisms to concentrate on a large amount of text that contains risk factors within the observable range, thereby ensuring the usefulness of the content obtained through text mining.

Our main contributions were as follows:

  • First, this study proposed a framework (TopicS-ClusterREV) based on natural language processing for identifying the risk factors of AR. We used pretrained word embeddings and text convolutional networks to process social media text. Our model can identify more risk factors from social media comments with high accuracy and recall. To the best of our knowledge, this is the first study to use natural language processing techniques to identify risk factors for AR in social media comments.
  • Second, this study proposes a topic-enhanced word-embedding model. TopicS enhances the thematic information of words by adding a task that predicts the theme to which the center word belongs. This generates high-dimensional word vector representations with semantic aggregation and theme enhancement. We trained 2 types of word vectors using both the Skip-gram and TopicS models and separately input them into each risk factor classifier. The results showed that TopicS outperformed the baseline on the text classification task, demonstrating the effectiveness of our topic-enhanced word-embedding model.
  • Finally, we introduced automatic and manual review mechanisms to improve the single-pass algorithm, which allowed us to effectively identify and focus on a large amount of text that contains risk factors within the observable range. We ultimately identified 28 categories of risk factors including the common risk factors that lead to most individuals developing symptoms and previously overlooked risk factors that were not within the scope of previous research.

Identification of AR Risk Factors Through Surveys

AR has become a major global issue with a substantial increase in its prevalence in recent years. In Europe, the prevalence of AR among Danish adults progressively increased from 19% to 32% over the past 3 decades [ 22 ]. Understanding the risk factors, such as genetic, environmental, and lifestyle factors, helps in the management of AR, thus motivating many studies to focus on identifying potential risk factors. These studies are summarized in Table 1 . From Table 1 , we observed that the previous studies were based on survey methods, including cross-sectional surveys, cohort studies, and case-control studies.

a We searched for the literature related to AR risk factors and presented 9 papers from the past decade to showcase the methods and the identified risk factors.

These studies typically recruited participants with symptoms of AR and control participants without AR symptoms from a specific age group or a particular geographical area, collected demographic information through questionnaires, and then conducted correlation analysis, such as logistic regression, to explore the relationship between those metadata and AR [ 32 ]. For instance, Gao et al [ 9 ] conducted a cross-sectional survey to investigate the prevalence and risk factors of adult self-reported AR in the plain lands and hilly areas of Shenmu City in China and analyzed the differences between regions. The content of the web-based questionnaire included demographic factors, smoking status, the comorbidities of other allergic disorders, family history of allergies, and place of residence. The unconditional logistic regression analysis was used to screen for factors influencing AR. Finally, they found that the prevalence of AR existed in regional differences. Genetic and environmental factors were the important risk factors associated with AR. However, these studies have 2 limitations. First, these studies specifically targeted certain age groups or geographical areas, and questionnaires can only gather data on specific pieces of information. Owing to the constraints of questionnaire surveys, it is challenging to identify potential risk factors that may be present in individuals’ daily lives. As a result, the risk factors identified through survey-based studies have limited scope and are incomplete and they may provide limited insights for a broader patient population. Second, the survey-based approach demands a commitment to long-term investigation and a massive effort to collect representative responses [ 10 ].

Identification of Disease Risk Factors From Social Media Through Text Mining

Social media sites provide a convenient way for users to continuously update their day-to-day activities, which allows large groups of people to create and share information, opinions, and experiences about health conditions through web-based discussion [ 11 ]. Hence, social media can be considered a new data source to assess population health. As shown in Table 2 , some studies have combined text-mining techniques to classify and summarize voluminous social media data to obtain knowledge about chronic disease risk factors. Zhang and Ram [ 33 ] extracted behavioral features from Twitter posts of asthma users using keywords from an existing knowledge base. Griffis et al [ 34 ] collected 25,000 tweets containing and not containing diabetes, identified 5000 common words, used logistic regression to determine which common words were high-frequency expressions of diabetes, and finally grouped these high-frequency words using latent Dirichlet allocation to obtain the risk factors for diabetes. Schäfer et al [ 35 ] used syntactic analysis to identify portions of risk factors occurring before or after causal terms, grouped these portions using latent Dirichlet allocation, and obtained the risk factors for gastric discomfort. Pradeepa et al [ 19 ] performed clustering on stroke-related tweets using the Probability Neural Network, used the Apriori algorithm to identify frequent word sets related to risk, and thus identified risk factors for stroke [ 19 ]. In addition to the aforementioned approaches that use shallow text features such as keywords, frequent word sets, high-frequency words, and syntactic features for disease risk factor identification, other studies [ 36 - 38 ] trained risk factor classifiers using machine learning methods such as Naive Bayes, Maximum Entropy Model, and Naive Bayes Classifier–Term Frequency Inverse Document Frequency. These classifiers predict the presence of risk factors in text based on discrete vector representations such as bag-of-words and n-gram.

a We searched for studies related to identifying disease risk factors based on social media data. We found 7 papers from the past decade, highlighting the social media platforms, data, methods, features, diseases, and risk factors involved in research.

b LDA: latent Dirichlet allocation.

c MLP: multilayer perceptron.

The current methods for identifying disease risk factors on social media fall into 2 categories: shallow text feature methods and discrete word vector representations. Shallow text feature techniques often fail to capture important risk factors resulting in low accuracy, whereas discrete word vector approaches struggle to keep up with the dynamic vocabulary of social media text, missing new words, and trending expressions, thus inadequately representing the information conveyed.

Word Embedding and Text Classification Based on Deep Learning

Natural language processing technology promotes text analysis based on social media comments [ 39 ]; this technology can learn the deeper semantic features of the comment text and the features that are consistent with the current context, according to different training corpus, to input a better text vector representation for downstream classification tasks. Some researchers have used large-scale pretrained language models [ 40 ], global matrix decomposition [ 41 ], and local context windows [ 42 ] for text vector representation. Local context windows are more suitable for semantically aggregating AR risk factors [ 43 ]. Skip-gram and Continuous Bag-of-Words Model (CBOW) are prediction-based methods that learn the semantic representation of a center word by predicting the most likely neighboring words within a window size in a corpus. When users narrate risk factors in their comments, they may also mention symptoms, treatments, and other topics. These global contexts may dilute the key features of the risk factors expression. CBOW averages the context words to predict the target word and tends to predict high-frequency words in the corpus. In contrast, Skip-gram gives each word a chance to be a center word, making it better at predicting rare words compared with CBOW [ 44 ]. Therefore, in situations where social media users express a wide variety of ideas, the Skip-gram model can yield satisfactory outcomes. Moreover, the Skip-gram approach uses word pair training, which facilitates the incorporation of topic information into words [ 45 ], resulting in the generation of high-dimensional word vectors that feature semantic aggregation and topic enhancement. Therefore, we selected Skip-gram as the word-embedding model for our study.

Text classification has evolved to deep learning models, mainly including CNN-based models [ 46 ], recurrent neural network (RNN)–based models [ 47 ], and transformer models [ 48 ]. For the CNN algorithm, convolutional networks can convolve text on the word vector dimensions and extract key information through pooling layer operations. Consequently, this algorithm is capable of using essential data for classification tasks. Therefore, we used TextCNN for classifier training and evaluated the performance of RNN and transformer models on this task.

The framework used in this study consisted of 3 parts as shown in Figure 1 . The first part was data collection and processing, aimed at obtaining a clean data set. The second part was risk factor identification, which included the proposed TopicS method and training of a risk factor classifier. The implementation steps were as follows: (1) semiautomatically constructing a risk factor topic dictionary, (2) generating high-dimensional word vectors enhanced by TopicS-generated topics, and (3) vectorizing annotated text and training a risk factor classifier. The third part is text clustering and keyword extraction, which uses the ClusterREV method to cluster the identified risk factors and extract keywords from every category.

how to conclude research paper

Zhihu is a Chinese social media platform where people discuss topics in an web-based forum format. In May 2022, the Zhihu subcommunity allergic rhinitis had 1.04 million discussions. The posts on this social media platform allow other users to comment [ 49 ], and people can explain their situations to provide support or seek help effectively. Therefore, these comments provide a rich source of data for investigating the risk factors reported by different users [ 50 ]. In this study, we trained domain-specific word representations based on experimental data. A relatively domain-specific input corpus [ 51 ] is better at extracting meaningful semantic relations than a generic pretrained language model [ 52 ]. We crawled all the data from May 2012 to May 2022 under the topic allergic rhinitis on Zhihu, obtaining a total of 9628 posts and 33,747 comments, including the post ID, comment ID, and post and comment content.

In this study, we preprocessed the data through regularization, stop word removal, and word separation. First, we removed special symbols, such as URLs and emoticons, in the comments through regularization and stop word removal to reduce the interference of noise with the text analysis task. Then, we compiled a dictionary of 169 specialized terms, including types of AR, medications, and comorbidities, to reduce the probability of incorrect word segmentation. After word separation, we obtained a lexicon of 68,863 words and ranked the words according to the number of occurrences. We found that the top 10,000 words accounted for 94.83% of the total words, suggesting that many words recurred and a relatively simple word vector could effectively train the model [ 53 ]. This further confirms the efficacy of our decision to use Skip-gram as the foundational model.

We observed ultrashort comment noise in the comments (eg, “Thank you!”). It is important to note that these ultrashort comments do not include any personal medical information. The ultrashort comments were filtered, resulting in 33,039 valid comments. This operation can effectively minimize the impact of noise on downstream text classification tasks. Table S1 in Multimedia Appendix 1 presents the examples of valid comments.

The data must be labeled before supervised learning and then trained end to end. If a comment directly mentions an allergen or indicates a condition that leads to the appearance or worsening of symptoms, the comment will be labeled as 1, indicating the presence of risk factors, as shown in Figure 2 .

how to conclude research paper

We randomly chose 2030 comments from the 33,039 comments, and 3 researchers labeled each comment as containing or not containing risk factors. To ensure high interannotator consistency, all 3 researchers annotated all 2030 comments. In cases with uncertainty in labeling, the 3 researchers discussed and arrived at a final label. After annotating and eliminating comments with religiously controversial content, 2000 labeled comments remained, consisting of 996 comments containing risk factors and 1004 comments not containing risk factors. The data set was divided into a 90% training set and a 10% test set. The 90% training set was further divided into 10 subsets, with 9 subsets used for training and the remaining subset used for validation, performing 10-fold cross-validation.

Topic Dictionary Construction

We used a combination of manual labeling and similarity calculation to identify keywords related to risk factors. Subsequently, we constructed a table of topic words using a semiautomated approach. The process of constructing the dictionary is depicted in Textbox 1 and is as follows: (1) label 400 randomly selected comments as described in the Annotation section, thereby obtaining 198 comments with risk factors; (2) extract risk factor phrases from annotated comments; (3) obtain risk factors topic word list; (4) remove duplicate word list, and the words in the current topic are used as seed words, word_set ; (5) use Skip-gram to find the top similar words to expand the topic words; (6) repeat steps 3 through 5 to expand the topic word; and (7) finally, obtain the topic words for the risk factor. A large weight was assigned to the risk factor theme words. Table S2 in Multimedia Appendix 1 shows examples of the risk factor topic dictionary.

Ethical Considerations

As the use of text data from social media involves user privacy, this study adopted the following steps for deidentification: (1) We removed user account information and retained only anonymous comment information. (2) We used regular expressions to match and delete URLs and email addresses in the comments. (3) During the annotation process, annotators received only text that did not involve personal information. To evaluate the quality of deidentification, we randomly selected 500 text items for manual inspection and did not find any instances containing personal identity information. Our data are sourced from public discussions on Zhihu, a social media platform that can be accessed without registration. We followed strict ethical research protocols similar to the guidelines by Eysenbach and Till [ 54 ]. In addition, to protect the anonymity of participants, we have implemented measures including the removal of user information and avoiding verbatim quotations to prevent identification through search engines, protecting the privacy and security of personal data. It should be mentioned that our study was focused on the post level; we do not anticipate any negative ethical impact from our analysis.

Topic-Enhanced Word Embedding

TopicS performed 2 tasks during training, as shown in Figure 3 . The first task was to predict the neighboring words within the window of the central word. The second task was to predict the topic of the central word; the topic dictionary used for this purpose is described in the Topic Dictionary Construction section.

how to conclude research paper

The specific formula calculations for the loss function design, parameter updates, and error backpropagation of TopicS are explained subsequently.

First, we defined the loss function. For each word in the corpus, we used it as the central word for a sliding operation with a window size of c ; let S be the training sequence ( w 1 ,w 2 ,...,w T ), whereas w i denotes the i th word in the sequence. The subscript T represents the total number of unique words in the corpus. In addition to predicting the contextual word of the central word, we must also predict the topic score of the central word. Therefore, the loss function comprised 2 parts: L cont and L topic , and the overall loss was denoted by L s . Our training objective was to minimize the loss function:

Finally, we can update the word representation.

Text Classification

In this study, we chose TextCNN as the classification model. In the risk factor identification task, some key semantic information is more important, and TextCNN can efficiently use the key information for classification with minimal cost consumption. We represented the manually annotated text as a vector matrix using high-dimensional word vector representations trained by the TopicS model, which aggregates local contextual and topic information and uses it as input for the TextCNN model. Then, the TextCNN algorithm leverages convolutional kernels of different sizes to extract multiple n-gram text features and uses convolutional operations in a fixed window to combine word representations to capture local information. Our input word vector combined the topic information of words, and the most important features in the convolution operation can be extracted using the maximum pooling operation as shown in Figure 4 .

Clustering With a Review Mechanism

The clustering task is to group similar risk factors. In this study, a large amount of text containing risk factors was clustered into a manually observable number of categories, making it easier to comprehend their content. This study enhances the single-pass algorithm and integrates it with a manual review to cluster the risk factors identified in the text classification, ensuring the validity of the clustering results. The main concept of single-pass clustering [ 55 ] is to match informational text items based on their similarity values without the need to determine the number of clusters in advance. This makes it suitable for clustering tasks with an unknown number of clusters. However, traditional single-pass clustering uses only one-loop traversal, which may result in previously entered text items completing the traversal earlier. This can cause their similarity to the previous topics to be slightly lower than the threshold and lead to them being recreated as new categories, ultimately affecting the clustering effect.

As shown in Figure 5 , we improved the single-pass algorithm by retraversing the categories that were clustered separately after all the text items had been traversed to handle any missed text. After the automated clustering was completed, we conducted a manual review to ensure the reliability of the clustering.

how to conclude research paper

Moreover, this study uses a keyword cloud visualization of category content to quickly understand the themes and characteristics of each cluster and compare the differences between different clusters. TextRank [ 56 ] was selected to extract category keywords, which considers only the voting scores of words in a single document; common words that frequently appear in a single document easily obtain high scores [ 57 ]. We treated each category as a single document for keyword extraction. As risk factors appear more frequently in categories, TextRank can effectively extract risk factors and surrounding words, preserving category content information as much as possible and reflecting the true content of the risk factors.

In this section, we present the performance of the classifier and the findings based on the categorization of all the comments in the clean data set using the classifier. Our approach involved visualizing the clustering results of the risk factors to comprehend the primary elements of these factors. We also explored the pathogenic mechanisms associated with these risk factors.

Classifier Performance

We used standard text-mining evaluation metrics such as accuracy, precision, recall, and F 1 -score to evaluate the performance. Precision assesses how many risk factors the model identifies correctly, and recall measures how many risk factors the model can identify on its test set. As we aimed to identify as many AR risk factors as possible to provide comprehensive references for individuals, recall was more important than precision in our study.

We set 7-word embedding dimensions ranging from 100 to 400. Table 3 displays the classification results of the TextCNN classification model with the 7 dimensions of Skip-gram and TopicS word vectors. In addition, TextRNN and transformer models were evaluated with the 7-word embedding dimensions of TopicS or Skip-gram, as shown in Tables S3 and S4 in Multimedia Appendix 1 ; the classification models performed better when the word-embedding dimension was 100 or 150, as shown in Table 4 , which includes the results with best-performing dimensions. This study conducted word representation learning on a domain-specific input corpus, where low dimensionality was found to be sufficient to represent the features of the corpus [ 58 ]. Moreover, TopicS not only improved precision but also significantly increased recall for all 3 models, as shown in Table 4 .

b Italicization represents that the metrics of TopicS are better than Skip-gram for each metric.

a Embed_size represents the word-embedding size.

b Italicization represents that the metrics of TopicS are better than Skip-gram for each model.

Table 4 shows that TextCNN has the highest accuracy and recall rate among the 3 classification models. The highest accuracy achieved by our classification model was 0.9594, which used a 150-dimension word-embedding representation obtained from TopicS. In other words, TextCNN can detect more risk factors and minimize the loss of risk factors resulting from classification errors. The CNN model can extract key information similar to n-grams in sentences. The combination of TopicS and TextCNN can enhance topic information and achieve an aggregation effect. Our implementation process was the simplest and consumed the least resources. Our model examined 30,372 comments and identified 5221 comments containing risk factors.

Risk Factor Clustering Results

We clustered the text items obtained from the text classification into 28 categories and extracted keywords from each category to better understand the content. Table 5 shows the top 5 categories and their corresponding keywords. The complete list can be found in Table S5 in Multimedia Appendix 1 . We used category 1 as an example to explain the category formation process and demonstrate the validity of the qualitative results. As shown in Table 4 , we labeled category 1 as Season based on the analysis of keyword weights and relative comments. The comments related to this category focused on seasonally induced AR, with factors such as changes in the weather during seasonal transitions and colder temperatures during winter, which can exacerbate symptoms. We also counted the number of text items in each category and found that seasonal, regional, mites, and weather changes were common risk factors for most patients. In addition, patients’ unhealthy lifestyle habits were also important risk factors widely present in research investigations. Furthermore, most patients reported experiencing symptoms at specific times (eg, “morning”), but researchers have paid little attention to the timing of symptom occurrence (which we refer to as time points).

The Possible Pathway of Several Risk Factors Triggers AR

We referred to the relevant literature on the risk factors associated with AR to confirm whether the extracted risk factors were consistent with the general medical consensus. Our findings are novel compared with those in the literature [ 59 ]. Previous survey-based studies have explored only the correlation between risk factors and AR, whereas our experimental data provide insight into the potential pathogenesis of reported risk factors. The following section provides a theoretical discussion of potential pathways for several risk factors that trigger AR:

  • Season : (1) seasonal risk factors are manifested in pollen allergens. Tree allergens such as elm and cypress pollen are prevalent in early spring, followed by ash, pine, and birch pollen in late spring. In summer, grasses, artemisia, and flowering plants grow vigorously owing to increased rainfall, leading to increased pollen spread from these plants. In autumn, weeds account for the largest proportion of pollen allergens. (2) Different climatic conditions in different seasons contribute to the development of allergies. For example, in early spring, frequent cold and high-pressure air activity in East Asia causes intense atmospheric circulation, resulting in alternating hot and cold temperatures that impair the immune regulatory function of the human body, leading to increased allergy attacks. In autumn, changeable weather, large temperature differences, and sunlight and UV radiation can stimulate allergic reactions in people with weak lungs or those who are prone to AR. In addition, seasonal changes and increasing temperature differences between day and night can disrupt the human immune system.
  • Poor habits : major keywords for this topic were “smoking,” “staying up late,” and “resistance.” (1) Habits such as staying up late, lack of exercise, smoking, and alcohol abuse can weaken immunity and resistance. Gangl et al [ 60 ] found that smoking can reduce the integrity and barrier function of respiratory epithelial cells, thereby making smokers more susceptible to allergens. (2) An irregular diet can damage the spleen and stomach, which is also a key factor in the development of AR. (3) The frequent use of air conditioning in summer can cause nasal mucosa irritation owing to temperature fluctuations. Long-term exposure to adverse stimuli can cause dryness of the nasal cavity and weaken the resistance of the mucosal epithelium, which may lead to AR.
  • Allergens : we grouped clusters that included mites, plants, food, animals, and mold as allergens. (1) The findings of this study suggest that dust mites are the primary allergen, and exposure to a certain concentration of indoor dust mites can lead to AR. The ideal humidity level for dust mite growth is between 75% and 80%, and dust mites tend to thrive during spring and autumn and in warm and humid environments. Studies have shown that a large number of dust mites may be attached to uncleaned air conditioning filters, confirming that air conditioning is an important route of transmission for household dust mites [ 61 ]. (2) Allergenic pollen species are closely related to regions and seasons, and some regions now provide pollen concentration and allergy index broadcasts based on meteorological conditions, which is highly convenient for individuals experiencing allergy. (3) Food allergens such as milk, eggs, wheat, soybeans, and peanuts can also trigger AR. (4) Apart from dust mites, other perennial indoor allergens include animal dander, cockroach excrement, and molds.
  • Outdoor environment : this topic had “dust,” “air quality,” “trust,” and “allergen” as high scoring words. (1) Various substances present in the outdoor environment can trigger AR. Industrialization has increased the content of aromatic hydrocarbon particles, ethanol, and formaldehyde in diesel exhaust, which can damage the mucous membrane and serve as a strong stimulus for AR attacks. (2) Air pollution can affect the distribution of allergens such as mold and pollen. In hazy weather, allergens tend to stay in the air longer, increasing the chance and duration of contact with the human body and leading to AR. (3) High winds can raise dust, pollen, mites, bacteria, and other allergenic factors, increasing their concentration in the air and making it easier to trigger AR.
  • Time points : patients with AR are more likely to experience symptoms during 2 specific time points, morning and evening. Schenkel et al [ 62 ] assessed the severity of 4 nasal symptoms (sneezing, blockage, nasal runny nose, and nasal itch) at different times of the day, revealing that morning and evening symptoms were the most severe. This may be because of the circadian rhythm, pollen concentration, or personal behavior exacerbating the symptoms. In the evening, when the wind subsides, pollen settles closer to the ground and can be inhaled more easily. In addition, although humans rest at night in a horizontal position, nasal ventilation may be more difficult, leading to more severe symptoms. In the morning, low temperatures can cause congestion and swelling of the nasal mucosa because of the temperature difference between the environment and the body. This cluster had words such as “evening,” “get up early,” and “nose” as highly rated words.

This theoretical discussion regarding the potential pathway of risk factors that trigger AR can guide the development of detailed AR intervention measures. For example, patients with AR can pay attention to pollen concentration and temperature changes and adjust their outings and clothing accordingly based on the characteristics of the season; they can set the air conditioner to turn on or off based on their waking time to reduce the inhalation of cold air when waking up. Furthermore, they can adjust their sleeping position to reduce the frequency of nighttime symptoms.

Principal Findings

This study aimed to identify the risk factors for AR based on social media comments. To do so, a data set of comments related to AR was collected, processed, and analyzed. The data set covered a consecutive period from May 2012 to May 2022. Overall, this analysis provided new insights into three main questions: (1) How many comments contained AR risk factor information? (2) How many categories can these risk factors be summarized into? (3) How do these risk factors trigger AR?

In assessing the identification of AR risk factors, we found that TopicS enhanced both precision and recall. TextCNN outperformed other models, achieving an accuracy of 0.9594 with a 150-dimension TopicS embedding. Analyzing 30,372 comments, our model pinpointed 5221 comments with risk factors. Categorizing the text items led to 28 distinct categories, with seasonal factors, regional variations, mites, weather changes, and unhealthy lifestyle habits emerging as common risks.

Furthermore, our research into AR risk factors revealed how risk factors trigger AR and uncovered the frequently reported, but underresearched, risk factors by affected individuals. Seasonal changes, especially during spring and autumn, increase exposure to pollen allergens, with varying climatic conditions affecting the development of allergies. Poor habits, such as smoking, irregular sleep, and frequent use of air conditioning, compromise immunity and heighten AR susceptibility. Dust mites, influenced by humidity, stand out as a primary allergen, with food items and indoor factors, such as animal dander, also triggering AR. Industrial pollutants and outdoor environmental factors amplify AR risk. Notably, AR symptoms intensify during mornings and evenings, which is likely influenced by circadian rhythms and environmental factors.

Limitations and Future Work

This study has some limitations. Our study was based on the self-reported nature of social media data, and the lack of more detailed information from the study participants was a concern. Our statistics showed that seasonal factors, regional variations, mites, weather changes, and unhealthy lifestyle habits emerge as common risk factors, which is consistent with the findings of other studies based on surveys. Although social media may lack in-depth patient information, it provides an effective method of collecting breadth of data. Social media data can be gathered 24 hours a day and are an extremely efficient way to rapidly update new knowledge into the risk factor knowledge base. In the future, our framework can be expanded in 2 ways. First, the framework can track the development trends and changes in AR risk factors by leveraging real-time internet data sets. Second, the framework can be generalized and extended to detect patterns, trends, and risk factors for other chronic diseases such as type 2 diabetes.

Conclusions

In this model improvement study, we proposed a topic-enhanced word-embedding model to improve the accuracy and recall of the text classification, namely to uncover less common or other types of risk factors based on social media data that have not been previously reported. The risk factors identified in this study can be a helpful reference for people with AR to reduce the development of the disease in their daily lives. This study establishes a knowledge base of potential risk factors for individuals who may not be aware of the factors that could trigger their symptoms. Patients can compare their lifestyle habits and medical history to identify their risk factors, which could help reduce the frequency of episodes and prevent the decline in their quality of life caused by blindly avoiding potential triggers. Our findings demonstrate the practicality and feasibility of using social media data for investigating disease knowledge. These findings may provide guidance for the development of management plans and interventions for AR.

The Supreme Court will hear the case against the abortion pill mifepristone on March 26. It's part of a two-drug regimen with misoprostol for abortions in the first 10 weeks of pregnancy.

A scientific paper that raised concerns about the safety of the abortion pill mifepristone was retracted by its publisher this week. The study was cited three times by a federal judge who ruled against mifepristone last spring. That case, which could limit access to mifepristone throughout the country, will soon be heard in the Supreme Court.

The now retracted study used Medicaid claims data to track E.R. visits by patients in the month after having an abortion. The study found a much higher rate of complications than similar studies that have examined abortion safety.

Sage, the publisher of the journal, retracted the study on Monday along with two other papers, explaining in a statement that "expert reviewers found that the studies demonstrate a lack of scientific rigor that invalidates or renders unreliable the authors' conclusions."

It also noted that most of the authors on the paper worked for the Charlotte Lozier Institute, the research arm of anti-abortion lobbying group Susan B. Anthony Pro-Life America, and that one of the original peer reviewers had also worked for the Lozier Institute.

The Sage journal, Health Services Research and Managerial Epidemiology , published all three research articles, which are still available online along with the retraction notice. In an email to NPR, a spokesperson for Sage wrote that the process leading to the retractions "was thorough, fair, and careful."

The lead author on the paper, James Studnicki, fiercely defends his work. "Sage is targeting us because we have been successful for a long period of time," he says on a video posted online this week . He asserts that the retraction has "nothing to do with real science and has everything to do with a political assassination of science."

He says that because the study's findings have been cited in legal cases like the one challenging the abortion pill, "we have become visible – people are quoting us. And for that reason, we are dangerous, and for that reason, they want to cancel our work," Studnicki says in the video.

In an email to NPR, a spokesperson for the Charlotte Lozier Institute said that they "will be taking appropriate legal action."

Role in abortion pill legal case

Anti-abortion rights groups, including a group of doctors, sued the federal Food and Drug Administration in 2022 over the approval of mifepristone, which is part of a two-drug regimen used in most medication abortions. The pill has been on the market for over 20 years, and is used in more than half abortions nationally. The FDA stands by its research that finds adverse events from mifepristone are extremely rare.

Judge Matthew Kacsmaryk, the district court judge who initially ruled on the case, pointed to the now-retracted study to support the idea that the anti-abortion rights physicians suing the FDA had the right to do so. "The associations' members have standing because they allege adverse events from chemical abortion drugs can overwhelm the medical system and place 'enormous pressure and stress' on doctors during emergencies and complications," he wrote in his decision, citing Studnicki. He ruled that mifepristone should be pulled from the market nationwide, although his decision never took effect.

Kacsmaryk is a Trump appointee who was a vocal abortion opponent before becoming a federal judge.

"I don't think he would view the retraction as delegitimizing the research," says Mary Ziegler , a law professor and expert on the legal history of abortion at U.C. Davis. "There's been so much polarization about what the reality of abortion is on the right that I'm not sure how much a retraction would affect his reasoning."

Ziegler also doubts the retractions will alter much in the Supreme Court case, given its conservative majority. "We've already seen, when it comes to abortion, that the court has a propensity to look at the views of experts that support the results it wants," she says. The decision that overturned Roe v. Wade is an example, she says. "The majority [opinion] relied pretty much exclusively on scholars with some ties to pro-life activism and didn't really cite anybody else even or really even acknowledge that there was a majority scholarly position or even that there was meaningful disagreement on the subject."

In the mifepristone case, "there's a lot of supposition and speculation" in the argument about who has standing to sue, she explains. "There's a probability that people will take mifepristone and then there's a probability that they'll get complications and then there's a probability that they'll get treatment in the E.R. and then there's a probability that they'll encounter physicians with certain objections to mifepristone. So the question is, if this [retraction] knocks out one leg of the stool, does that somehow affect how the court is going to view standing? I imagine not."

It's impossible to know who will win the Supreme Court case, but Ziegler thinks that this retraction probably won't sway the outcome either way. "If the court is skeptical of standing because of all these aforementioned weaknesses, this is just more fuel to that fire," she says. "It's not as if this were an airtight case for standing and this was a potentially game-changing development."

Oral arguments for the case, Alliance for Hippocratic Medicine v. FDA , are scheduled for March 26 at the Supreme Court. A decision is expected by summer. Mifepristone remains available while the legal process continues.

OpenAI teases an amazing new generative video model called Sora

The firm is sharing Sora with a small group of safety testers but the rest of us will have to wait to learn more.

  • Will Douglas Heaven archive page

OpenAI has built a striking new generative video model called Sora that can take a short text description and turn it into a detailed, high-definition film clip up to a minute long.

Based on four sample videos that OpenAI shared with MIT Technology Review ahead of today’s announcement, the San Francisco–based firm has pushed the envelope of what’s possible with text-to-video generation (a hot new research direction that we flagged as a trend to watch in 2024 ).

“We think building models that can understand video, and understand all these very complex interactions of our world, is an important step for all future AI systems,” says Tim Brooks, a scientist at OpenAI.

But there’s a disclaimer. OpenAI gave us a preview of Sora (which means sky in Japanese) under conditions of strict secrecy. In an unusual move, the firm would only share information about Sora if we agreed to wait until after news of the model was made public to seek the opinions of outside experts. [Editor’s note: We’ve updated this story with outside comment below.] OpenAI has not yet released a technical report or demonstrated the model actually working. And it says it won’t be releasing Sora anytime soon. [ Update: OpenAI has now shared more technical details on its website.]

The first generative models that could produce video from snippets of text appeared in late 2022. But early examples from Meta , Google, and a startup called Runway were glitchy and grainy. Since then, the tech has been getting better fast. Runway’s gen-2 model, released last year, can produce short clips that come close to matching big-studio animation in their quality. But most of these examples are still only a few seconds long.  

The sample videos from OpenAI’s Sora are high-definition and full of detail. OpenAI also says it can generate videos up to a minute long. One video of a Tokyo street scene shows that Sora has learned how objects fit together in 3D: the camera swoops into the scene to follow a couple as they walk past a row of shops.

OpenAI also claims that Sora handles occlusion well. One problem with existing models is that they can fail to keep track of objects when they drop out of view. For example, if a truck passes in front of a street sign, the sign might not reappear afterward.  

In a video of a papercraft underwater scene, Sora has added what look like cuts between different pieces of footage, and the model has maintained a consistent style between them.

It’s not perfect. In the Tokyo video, cars to the left look smaller than the people walking beside them. They also pop in and out between the tree branches. “There’s definitely some work to be done in terms of long-term coherence,” says Brooks. “For example, if someone goes out of view for a long time, they won’t come back. The model kind of forgets that they were supposed to be there.”

Impressive as they are, the sample videos shown here were no doubt cherry-picked to show Sora at its best. Without more information, it is hard to know how representative they are of the model’s typical output.   

It may be some time before we find out. OpenAI’s announcement of Sora today is a tech tease, and the company says it has no current plans to release it to the public. Instead, OpenAI will today begin sharing the model with third-party safety testers for the first time.

In particular, the firm is worried about the potential misuses of fake but photorealistic video . “We’re being careful about deployment here and making sure we have all our bases covered before we put this in the hands of the general public,” says Aditya Ramesh, a scientist at OpenAI, who created the firm’s text-to-image model DALL-E .

But OpenAI is eyeing a product launch sometime in the future. As well as safety testers, the company is also sharing the model with a select group of video makers and artists to get feedback on how to make Sora as useful as possible to creative professionals. “The other goal is to show everyone what is on the horizon, to give a preview of what these models will be capable of,” says Ramesh.

To build Sora, the team adapted the tech behind DALL-E 3, the latest version of OpenAI’s flagship text-to-image model. Like most text-to-image models, DALL-E 3 uses what’s known as a diffusion model. These are trained to turn a fuzz of random pixels into a picture.

Sora takes this approach and applies it to videos rather than still images. But the researchers also added another technique to the mix. Unlike DALL-E or most other generative video models, Sora combines its diffusion model with a type of neural network called a transformer.

Transformers are great at processing long sequences of data, like words. That has made them the special sauce inside large language models like OpenAI’s GPT-4 and Google DeepMind’s Gemini . But videos are not made of words. Instead, the researchers had to find a way to cut videos into chunks that could be treated as if they were. The approach they came up with was to dice videos up across both space and time. “It’s like if you were to have a stack of all the video frames and you cut little cubes from it,” says Brooks.

The transformer inside Sora can then process these chunks of video data in much the same way that the transformer inside a large language model processes words in a block of text. The researchers say that this let them train Sora on many more types of video than other text-to-video models, varied in terms of resolution, duration, aspect ratio, and orientation. “It really helps the model,” says Brooks. “That is something that we’re not aware of any existing work on.”

“From a technical perspective it seems like a very significant leap forward,” says Sam Gregory, executive director at Witness, a human rights organization that specializes in the use and misuse of video technology. “But there are two sides to the coin,” he says. “The expressive capabilities offer the potential for many more people to be storytellers using video. And there are also real potential avenues for misuse.” 

OpenAI is well aware of the risks that come with a generative video model. We are already seeing the large-scale misuse of deepfake images . Photorealistic video takes this to another level.

Gregory notes that you could use technology like this to misinform people about conflict zones or protests. The range of styles is also interesting, he says. If you could generate shaky footage that looked like something shot with a phone, it would come across as more authentic.

The tech is not there yet, but generative video has gone from zero to Sora in just 18 months. “We’re going to be entering a universe where there will be fully synthetic content, human-generated content and a mix of the two,” says Gregory.

The OpenAI team plans to draw on the safety testing it did last year for DALL-E 3. Sora already includes a filter that runs on all prompts sent to the model that will block requests for violent, sexual, or hateful images, as well as images of known people. Another filter will look at frames of generated videos and block material that violates OpenAI’s safety policies.

OpenAI says it is also adapting a fake-image detector developed for DALL-E 3 to use with Sora. And the company will embed industry-standard C2PA tags , metadata that states how an image was generated, into all of Sora’s output. But these steps are far from foolproof. Fake-image detectors are hit-or-miss. Metadata is easy to remove, and most social media sites strip it from uploaded images by default.  

“We’ll definitely need to get more feedback and learn more about the types of risks that need to be addressed with video before it would make sense for us to release this,” says Ramesh.

Brooks agrees. “Part of the reason that we’re talking about this research now is so that we can start getting the input that we need to do the work necessary to figure out how it could be safely deployed,” he says.

Migrant encounters at the u.s.-mexico border hit a record high at the end of 2023.

The U.S. Border Patrol had nearly 250,000 encounters with migrants crossing into the United States from Mexico in December 2023, according to government statistics . That was the highest monthly total on record, easily eclipsing the previous peak of about 224,000 encounters in May 2022.

A line chart showing that 2023 ended with more migrant encounters at U.S.-Mexico border than any month on record.

The monthly number of encounters has soared since 2020, when the coronavirus pandemic temporarily forced the U.S.-Mexico border to close and slowed migration across much of the world . In April 2020, the Border Patrol recorded around 16,000 encounters – among the lowest monthly totals in decades.

This Pew Research Center analysis examines migration patterns at the U.S.-Mexico border using  current  and  historical data  from U.S. Customs and Border Protection, the federal agency that includes the U.S. Border Patrol. The analysis is based on a metric known as migrant encounters.

The term “encounters” refers to two distinct types of events:

  • Apprehensions: Migrants are taken into custody in the United States, at least temporarily, to await a decision on whether they can remain in the country legally, such as by being granted asylum. Apprehensions are carried out under  Title 8 of the U.S. code , which deals with immigration law.
  • Expulsions: Migrants are immediately expelled to their home country or last country of transit without being held in U.S. custody. Expulsions are carried out under Title 42 of the U.S. code, a previously  rarely used section of the law  that the Trump administration invoked during the early stages of the COVID-19 pandemic . The law empowers federal health authorities to stop migrants from entering the country if it is determined that barring them could prevent the spread of contagious diseases. The Biden administration stopped the use of Title 42 in May 2023, when the federal government declared an end to the COVID-19 public health emergency .

It is important to note that encounters refer to events, not people, and that some migrants are encountered more than once. As a result, the overall number of encounters may overstate the number of distinct individuals involved.

This analysis is limited to monthly encounters between ports of entry involving the Border Patrol. It excludes encounters at ports of entry involving the Office of Field Operations.

Since then, the monthly number of migrant encounters at the U.S.-Mexico border has surpassed 200,000 on 10 separate occasions. That threshold previously hadn’t been reached since March 2000, when there were about 220,000 encounters.

It’s not clear whether the recent high numbers of encounters at the border will persist in 2024. In January, encounters fell to around 124,000 , according to the latest available statistics.

  • Apprehensions: Migrants are taken into custody in the U.S., at least temporarily, to await a decision on whether they can remain in the country legally, such as by being granted asylum. Apprehensions are carried out under  Title 8 of the U.S. code , which deals with immigration law.

  • Expulsions : Migrants are immediately expelled to their home country or last country of transit without being held in U.S. custody. Expulsions are carried out under Title 42 of the U.S. code, a previously  rarely used section of the law  that the Trump administration invoked during the early stages of the COVID-19 pandemic. The law empowers federal health authorities to stop migrants from entering the country if it is determined that barring them could prevent the spread of contagious diseases. In the early months of the pandemic in the U.S., the Border Patrol relied heavily on Title 42 to expel most of the migrants it encountered at the border. The Biden administration stopped the use of Title 42 in May 2023, when the federal government declared an end to the COVID-19 public health emergency . Since then, the Border Patrol has been apprehending migrants within the U.S. instead of expelling them from the country.

Who is crossing the U.S.-Mexico border?

An area chart showing that a growing share of migrant encounters involve people traveling in families.

In December 2023, most encounters at the U.S.-Mexico border (54%) involved migrants traveling as single adults, while 41% involved people traveling in families and 5% involved unaccompanied minors.

In recent months, a growing number of encounters have involved people traveling in families. In December 2023, the Border Patrol had nearly 102,000 encounters with family members, up from around 61,000 a year earlier.

There has also been a shift in migrants’ origin countries. Historically, most encounters at the southwestern border have involved citizens of Mexico or the Northern Triangle nations of El Salvador, Guatemala and Honduras. But in December 2023, 54% of encounters involved citizens of countries other than these four nations.

An area chart showing that most border encounters now involve people from countries other than Mexico and Northern Triangle.

Venezuelans, in particular, stand out. Nearly 47,000 migrant encounters in December 2023 involved citizens of Venezuela, up from about 6,000 a year earlier. The number of encounters involving Venezuelans was second only to the approximately 56,000 involving Mexicans in December 2023.

There has also been a sharp increase in encounters with citizens of China, despite its distance from the U.S.-Mexico border. The Border Patrol reported nearly 6,000 encounters with Chinese citizens at the southwestern border in December 2023, up from around 900 a year earlier.

How do Americans view the situation at the border?

The American public is broadly dissatisfied with how things are going at the border, according to a new Pew Research Center survey .

Eight-in-ten U.S. adults say the government is doing a very or somewhat bad job dealing with the large number of migrants seeking to enter the U.S. at the border with Mexico. And nearly as many say the situation is either a “crisis” (45%) or a “major problem” (32%) for the U.S.
