what to put in a conclusion in a research paper

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.

Frequently Asked Questions

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 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.

How to Write a Conclusion for a Research Paper

• 3-minute read
• 29th August 2023

If you’re writing a research paper, the conclusion is your opportunity to summarize your findings and leave a lasting impression on your readers. In this post, we’ll take you through how to write an effective conclusion for a research paper and how you can:

·   Reword your thesis statement

·   Highlight the significance of your research

·   Discuss limitations

·   Connect to the introduction

·   End with a thought-provoking statement

Rewording Your Thesis Statement

Begin your conclusion by restating your thesis statement in a way that is slightly different from the wording used in the introduction. Avoid presenting new information or evidence in your conclusion. Just summarize the main points and arguments of your essay and keep this part as concise as possible. Remember that you’ve already covered the in-depth analyses and investigations in the main body paragraphs of your essay, so it’s not necessary to restate these details in the conclusion.

Highlighting the Significance of Your Research

The conclusion is a good place to emphasize the implications of your research . Avoid ambiguous or vague language such as “I think” or “maybe,” which could weaken your position. Clearly explain why your research is significant and how it contributes to the broader field of study.

Here’s an example from a (fictional) study on the impact of social media on mental health:

Discussing Limitations

Although it’s important to emphasize the significance of your study, you can also use the conclusion to briefly address any limitations you discovered while conducting your research, such as time constraints or a shortage of resources. Doing this demonstrates a balanced and honest approach to your research.

Connecting to the Introduction

In your conclusion, you can circle back to your introduction , perhaps by referring to a quote or anecdote you discussed earlier. If you end your paper on a similar note to how you began it, you will create a sense of cohesion for the reader and remind them of the meaning and significance of your research.

Ending With a Thought-Provoking Statement

Consider ending your paper with a thought-provoking and memorable statement that relates to the impact of your research questions or hypothesis. This statement can be a call to action, a philosophical question, or a prediction for the future (positive or negative). Here’s an example that uses the same topic as above (social media and mental health):

How to write a strong conclusion for your research paper

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.

How to Write a Conclusion for a Research Paper

By the time you write the conclusion, you should have pointed out in the body of your research paper why your topic is important to the reader, and you should have presented the reader with all your arguments. It is critical that you do not introduce new information or ideas in your conclusion. If you find that you have not yet made the arguments you wished to make or pointed out evidence you feel is crucial to your reader’s understanding of your subject, you are not yet ready to write the conclusion; add another body paragraph before writing the conclusion.

Your research paper should have a strong, succinct concluding section, where you draw together your findings. Think of it as a conclusion, not a summary. The difference is that you are reaching overall judgments about your topic, not summarizing everything you wrote about it. How to write a conclusion for a research paper? The focus should be on:

• Saying what your research has found, what the findings mean, and how well they support the argument of your thesis statement.
• Establishing the limits of your argument: How widely does it apply? What are the strengths and weaknesses of your method? How clear-cut are your findings?
• Explaining how your findings and argument fit into your field, relating them to answers others have given and to the existing literature.

You may also want to add some concise comments about possible future developments or what kind of research should come next, but don’t lay it on too thick. The place of honor goes to your own explanation. Don’t spend too much of your final section criticizing others. Don’t introduce any big new topics or ideas. You certainly don’t expect to see new characters in the last scene of a movie. For the same reasons, you shouldn’t find any big new topics being introduced in the last paragraphs of a research paper.

Your concluding statement should focus on what your findings mean. How do you interpret them? Are they just as easily explained by alternative theories or other perspectives? Here, you are returning to the questions that first animated you and answering them, based on your research. You not only want to give the answers; you also want to explain their significance. What do they mean for policy, theory, literary interpretation, moral action, or whatever? You are answering the old, hard question: “So what?”

Be wary of overreaching. You really need to do two things at the same time: explain the significance of your findings and stake out their limits. You may have a hunch that your findings apply widely but, as a social scientist, you need to assess whether you can say so confidently, based on your current research. Your reader needs to know: “Do these findings apply to all college students, to all adults, or only to white mice?” White mice don’t come up much in the humanities, but the reader still wants to know how far your approach reaches. Does your analysis apply only to this novel or this writer, or could it apply to a whole literary genre?

Make it a priority to discuss these conclusions with your professor or adviser. The main danger here is that students finally reach this final section with only a week or two left before the due date. They don’t have enough time to work through their conclusions and revise them. That leaves the research paper weakest at the end, precisely where it should be strongest, nailing down the most significant points.

Begin discussing your major findings with your adviser while you are still writing the heart of the research paper. Of course, your conclusions will be tentative at that stage, but it helps to begin talking about them. As always, a little writing helps. You could simply list your main findings or write out a few paragraphs about them. Either would serve as a launching pad for meetings with your adviser. You will find these discussions also shed light on the research that leads to these findings. That, in turn, will strengthen your middle sections. Later, when you draft the conclusion, review your notes on these talks and the short documents you wrote for them. They will serve as prewriting for the final section.

The opening sentence of the conclusion should flow smoothly and logically from the transition sentence in the previous paragraph and lead the reader to reflect on your thesis. A good conclusion however, does not simply restate the thesis. You want to remind the reader of the thesis in your conclusion but reword it in a stronger fashion so that it is interesting and memorable to your audience.After reminding the reader of the thesis, the conclusion should then reflect on the topics in the body of the paper and summarize the key findings of your research. If you are writing a persuasive paper, it should summarize your key arguments and logically point your readers to the conclusion you wish them to reach.

Phrases for Conclusions of Research Papers

• All this requires us to (propose the next action or an alternative idea).
• Altogether, these findings indicate (point out the logical result).
• Finally, it is important to note (make your strongest point and follow with a recommendation).
• In conclusion (restate your thesis with greater emphasis).
• It is evident that (point out the logical result or obvious next action).
• In light of the evidence, (restate your thesis with greater emphasis).
• In short, (summarize your findings).

Examples of Strong Conclusions

As an example of how to end your research paper, let’s turn again to John Dower’s splendid book on postwar Japan, Embracing Defeat: Japan in the Wake of World War II . In the final pages, Dower pulls together his findings on war-ravaged Japan and its efforts to rebuild. He then judges the legacies of that period: its continuing impact on the country’s social, political, and economic life. Some insights are unexpected, at least to me. He argues that Japan has pursued trade protection as the only acceptable avenue for its persistent nationalism. America’s overwhelming power and Japan’s self-imposed restraints—the intertwined subjects of the book—blocked any political or military expression of Japan’s nationalist sentiment. Those avenues were simply too dangerous, he says, while economic nationalism was not. Dower ends with these paragraphs:

The Japanese economists and bureaucrats who drafted the informal 1946 blueprint for a planned economy were admirably clear on these objectives [of “demilitarization and democratization”]. They sought rapid recovery and maximum economic growth, of course—but they were just as concerned with achieving economic demilitarization and economic democracy. . . . Japan became wealthy. The standard of living rose impressively at every level of society. Income distribution was far more equitable than in the United States. Job security was assured. Growth was achieved without inordinate dependence on a military-industrial complex or a thriving trade in armaments. These are hardly trivial ideas, but they are now being discarded along with all the deservedly bankrupt aspects of the postwar system. The lessons and legacies of defeat have been many and varied indeed; and their end is not yet in sight. (John W. Dower, Embracing Defeat: Japan in the Wake of World War II . New York: W. W. Norton, 1999, pp. 563–64)

Remember the anecdotal opening of Herbert’s book Impressionism: Art, Leisure, and Parisian Society , with Henry Tuckerman’s 1867 arrival in a much-changed Paris? (see research paper introduction examples) Herbert strikes a completely different tone in his conclusion. It synthesizes the art history he has presented, offers a large judgment about where Impressionism fits among art movements, and suggests why exhibitions of Monet, Manet, and Renoir are still so popular. He manages to do all that in a few well-crafted sentences:

Although we credit [Impressionism] with being the gateway to modern art, we also treat it as the last of the great Western styles based upon a perception of harmony with natural vision. That harmony, long since lost to us in this century of urbanization, industrialization, and world wars, remains a longed-for idea, so we look back to Impressionism as the painting of a golden era. We flock into exhibitions of paintings that represent cafes, boating, promenading, and peaceful landscapes precisely because of our yearning for less troubled times. The only history that we feel deeply is the kind that is useful to us. Impressionism still looms large at the end of the twentieth century because we use its leisure-time subjects and its brilliantly colored surfaces to construct a desirable history. (Herbert, Impressionism , p. 306)

Robert Dallek offers similarly accessible, powerful judgments in his conclusion to Flawed Giant: Lyndon Johnson and His Times, 1961–1973 :

[Johnson’s] presidency was a story of great achievement and terrible failure, of lasting gains and unforgettable losses. . . . In a not so distant future, when coming generations have no direct experience of the man and the passions of the sixties are muted, Johnson will probably be remembered as a President who faithfully reflected the country’s greatness and limitations—a man notable for his successes and failures, for his triumphs and tragedy. Only one thing seems certain: Lyndon Johnson will not join the many obscure—almost nameless, faceless—Presidents whose terms of office register on most Americans as blank slates. He will not be forgotten. (Robert Dallek, Flawed Giant: Lyndon Johnson and His Times, 1961–1973 . New York: Oxford University Press, 1998, p. 628)

Some writers not only synthesize their findings or compare them to others; they use the conclusion to say what their work means for appropriate methods or subject matter in their field. That is what Robert Bruegmann does in his final statement in The Architects and the City: Holabird & Roche of Chicago, 1880–1918 . His conclusion goes beyond saying that this was a great architectural firm or that it designed buildings of lasting importance. Bruegmann tells us that Holabird & Roche helped shape modern Chicago and that its work, properly studied, helps us understand “the city as the ultimate human artifact”:

Traditional architectural history has tended to see the city less as a process than as a product, a collection of high art architectural objects in a setting dominated by mundane buildings of little interest. This tended to perpetuate a destructive and divisive attitude about the built environment, suggesting that only a few buildings are worthy of careful study and preservation while all others are mere backdrop. I hope that these explorations in the work of Holabird & Roche have shed light on parts of the city rarely visited by the architectural historian and on some little explored aspects of its history. If so, perhaps it has achieved its most basic goal: providing an insight into the city as the ultimate human artifact, our most complex and prodigious social creation, and the most tangible result of the actions over time of all its citizens. (Robert Bruegmann, The Architects and the City: Holabird & Roche of Chicago, 1880–1918 . Chicago: University of Chicago Press, 1997, p. 443)

These are powerful conclusions, ending major works of scholarship on a high note. What concluding paragraphs should never do is gaze off into the sunset, offer vague homilies, or claim you have found the meaning of human existence. Be concrete. Stick to your topic. Make sure your research paper conclusions stand on solid ground. Avoid vague platitudes in your conclusion. Your goal should be reaching strong, sound judgments, firmly grounded in your readings and research. Better to claim too little than too much. Best of all, claim what you’ve earned the right to say: what your research really means.

Having finished the main parts of a research paper you can write an abstract.

Back to  How To Write A Research Paper .

ORDER HIGH QUALITY CUSTOM PAPER

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.”)

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.
• Providing recommendations for future research or action : The conclusion suggests practical recommendations for future research or action, based on the findings of the study.
• Providing closure to the research paper : The conclusion provides a sense of closure to the research paper, tying together the different sections of the paper and leaving a lasting impression on the reader.
• Demonstrating the writer’s contribution to the field : The conclusion provides the writer with an opportunity to showcase their contribution to the field and to inspire further research and action.

Limitations of Research Paper Conclusion

While the conclusion of a research paper has many advantages, it also has some limitations that should be considered, including:

• I nability to address all aspects of the research: Due to the limited space available in the conclusion, it may not be possible to address all aspects of the research in detail.
• Subjectivity : While the conclusion should be objective, it may be influenced by the writer’s personal biases or opinions.
• Lack of new information: The conclusion should not introduce new information that has not been discussed in the body of the research paper.
• Lack of generalizability: The conclusions drawn from the research may not be applicable to other contexts or populations, limiting the generalizability of the study.
• Misinterpretation by the reader: The reader may misinterpret the conclusions drawn from the research, leading to a misunderstanding of the findings.

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 derived from the findings of your study and, if applicable based on your analysis, explain new areas for future research. For most college-level research papers, two or three well-developed paragraphs is sufficient for a conclusion, although in some cases, more paragraphs may be required in describing the key findings and highlighting their significance.

Importance of a Good Conclusion

A well-written conclusion provides 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  your answer to the "So What?" question by placing the study within the context of how your research advances past studies 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 [first identified in your literature review section] has been addressed by your research and why this contribution is significant.
• Demonstrating the importance of your ideas . Don't be shy. The conclusion offers an 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 general function of your paper's conclusion is to restate the main argument . It reminds the reader of your main argument(s) strengths and reiterates the most important evidence supporting those argument(s). Do this by clearly summarizing the context, background, and the necessity of examining the research problem in relation to an issue, controversy, or a gap found in the literature. However, make sure 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 paper.

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

• Present your conclusions in clear, concise language. Re-state the purpose of your study, then describe how your findings differ or support those of other studies and why [i.e., describe what were the unique, new, or crucial 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 but that further analysis should take place beyond the scope of your investigation.

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 [this is opposite of the introduction, which begins with general discussion of the context and ends with a detailed description of the research problem]. 

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. If asked to think introspectively about the topic, 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:

• If your paper addresses a critical, contemporary problem, warn readers of the possible consequences of not attending to the problem proactively based on the evidence presented in your study.
• 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 leading to positive change.
• 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 source would be from a source cited in 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 from your study 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 [topic studied within the field of study] to the specific [the research problem]. However, in the conclusion, your task is to move the discussion from specific [your research problem] back to a general discussion framed around the implications and significance of your findings [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 the structure of your paper as an hourglass--start with a broad introduction and review of the literature, move to the specific method of analysis and the 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. They 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 negative or surprising 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 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, but it often represents the key takeaway for your reader.

Failure to match the objectives of your research Often research objectives in the social and behavioral sciences change while the research is being carried out due to unforeseen factors or unanticipated variables. 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 as a researcher 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 concerning the validity and realiability of your research.

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 that they are reaching the end of your paper. You'll irritate your readers if you belabor the obvious.

Assan, Joseph. "Writing the Conclusion Chapter: The Good, the Bad and the Missing." Liverpool: Development Studies Association (2009): 1-8.

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. This is why the conclusion rarely has citations to sources that haven't been referenced elsewhere in your paper. If you have new information to present, add it to the discussion or other appropriate section of the paper. Note that, although no 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 have presented, and position your findings within the larger context of scholarship on the topic, including describing how your research contributes new insights to that scholarship.

How to Write a Conclusion for a Research Paper

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.

Published on September 6, 2022 by Tegan George and Shona McCombes. Revised on November 20, 2023.

The conclusion is the very last part of your thesis or dissertation . It should be concise and engaging, leaving your reader with a clear understanding of your main findings, as well as the answer to your research question .

In it, you should:

• Clearly state the answer to your main research question
• Summarize and reflect on your research process
• Make recommendations for future work on your thesis or dissertation topic
• Show what new knowledge you have contributed to your field
• Wrap up your thesis or dissertation

While your conclusion contains similar elements to your discussion section , they are not the same thing.

Your conclusion should be shorter and more general than your discussion. Instead of repeating literature from your literature review , discussing specific research results , or interpreting your data in detail, concentrate on making broad statements that sum up the most important insights of your research.

As a rule of thumb, your conclusion should not introduce new data, interpretations, or arguments.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

Depending on whether you are writing a thesis or dissertation, your length will vary. Generally, a conclusion should make up around 5–7% of your overall word count.

An empirical scientific study will often have a short conclusion, concisely stating the main findings and recommendations for future research. A humanities dissertation topic or systematic review , on the other hand, might require more space to conclude its analysis, tying all the previous sections together in an overall argument.

Your conclusion should begin with the main question that your thesis or dissertation aimed to address. This is your final chance to show that you’ve done what you set out to do, so make sure to formulate a clear, concise answer.

• Don’t repeat a list of all the results that you already discussed
• Do synthesize them into a final takeaway that the reader will remember.

An empirical thesis or dissertation conclusion may begin like this:

A case study –based thesis or dissertation conclusion may begin like this:

In the second example, the research aim is not directly restated, but rather added implicitly to the statement. To avoid repeating yourself, it is helpful to reformulate your aims and questions into an overall statement of what you did and how you did it.

Your conclusion is an opportunity to remind your reader why you took the approach you did, what you expected to find, and how well the results matched your expectations.

To avoid repetition , consider writing more reflectively here, rather than just writing a summary of each preceding section. Consider mentioning the effectiveness of your methodology , or perhaps any new questions or unexpected insights that arose in the process.

You can also mention any limitations of your research, but only if you haven’t already included these in the discussion. Don’t dwell on them at length, though—focus on the positives of your work.

• While x limits the generalizability of the results, this approach provides new insight into y .
• This research clearly illustrates x , but it also raises the question of y .

You may already have made a few recommendations for future research in your discussion section, but the conclusion is a good place to elaborate and look ahead, considering the implications of your findings in both theoretical and practical terms.

• Based on these conclusions, practitioners should consider …
• To better understand the implications of these results, future studies could address …
• Further research is needed to determine the causes of/effects of/relationship between …

When making recommendations for further research, be sure not to undermine your own work. Relatedly, while future studies might confirm, build on, or enrich your conclusions, they shouldn’t be required for your argument to feel complete. Your work should stand alone on its own merits.

Just as you should avoid too much self-criticism, you should also avoid exaggerating the applicability of your research. If you’re making recommendations for policy, business, or other practical implementations, it’s generally best to frame them as “shoulds” rather than “musts.” All in all, the purpose of academic research is to inform, explain, and explore—not to demand.

Make sure your reader is left with a strong impression of what your research has contributed to the state of your field.

Some strategies to achieve this include:

• Returning to your problem statement to explain how your research helps solve the problem
• Referring back to the literature review and showing how you have addressed a gap in knowledge
• Discussing how your findings confirm or challenge an existing theory or assumption

Again, avoid simply repeating what you’ve already covered in the discussion in your conclusion. Instead, pick out the most important points and sum them up succinctly, situating your project in a broader context.

The end is near! Once you’ve finished writing your conclusion, it’s time to wrap up your thesis or dissertation with a few final steps:

• It’s a good idea to write your abstract next, while the research is still fresh in your mind.
• Next, make sure your reference list is complete and correctly formatted. To speed up the process, you can use our free APA citation generator .
• Once you’ve added any appendices , you can create a table of contents and title page .
• Finally, read through the whole document again to make sure your thesis is clearly written and free from language errors. You can proofread it yourself , ask a friend, or consider Scribbr’s proofreading and editing service .

Here is an example of how you can write your conclusion section. Notice how it includes everything mentioned above:

V. Conclusion

The current research aimed to identify acoustic speech characteristics which mark the beginning of an exacerbation in COPD patients.

The central questions for this research were as follows: 1. Which acoustic measures extracted from read speech differ between COPD speakers in stable condition and healthy speakers? 2. In what ways does the speech of COPD patients during an exacerbation differ from speech of COPD patients during stable periods?

All recordings were aligned using a script. Subsequently, they were manually annotated to indicate respiratory actions such as inhaling and exhaling. The recordings of 9 stable COPD patients reading aloud were then compared with the recordings of 5 healthy control subjects reading aloud. The results showed a significant effect of condition on the number of in- and exhalations per syllable, the number of non-linguistic in- and exhalations per syllable, and the ratio of voiced and silence intervals. The number of in- and exhalations per syllable and the number of non-linguistic in- and exhalations per syllable were higher for COPD patients than for healthy controls, which confirmed both hypotheses.

However, the higher ratio of voiced and silence intervals for COPD patients compared to healthy controls was not in line with the hypotheses. This unpredicted result might have been caused by the different reading materials or recording procedures for both groups, or by a difference in reading skills. Moreover, there was a trend regarding the effect of condition on the number of syllables per breath group. The number of syllables per breath group was higher for healthy controls than for COPD patients, which was in line with the hypothesis. There was no effect of condition on pitch, intensity, center of gravity, pitch variability, speaking rate, or articulation rate.

This research has shown that the speech of COPD patients in exacerbation differs from the speech of COPD patients in stable condition. This might have potential for the detection of exacerbations. However, sustained vowels rarely occur in spontaneous speech. Therefore, the last two outcome measures might have greater potential for the detection of beginning exacerbations, but further research on the different outcome measures and their potential for the detection of exacerbations is needed due to the limitations of the current study.

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• Generic concluding phrases (e.g. “In conclusion …”)
• Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

How to Write a Conclusion for a Research Paper

• Posted on May 12, 2023

The key to an impactful research paper is crafting an effective conclusion. The conclusion provides a final opportunity to make a lasting impression on the reader by providing a powerful summary of the main argument and key findings.

A well-written conclusion not only summarizes your research but also ties everything back to your thesis statement. Plus, it provides important takeaways for your reader, highlighting what they should remember from your research and how it contributes to the larger academic discourse.

Crafting an impactful conclusion can be tricky, especially in argumentative papers. However, with our expert tips and tricks, you can rest assured that your conclusion will effectively restate the main argument and thesis statement in a way that resonates with your audience and elevates your research to new heights.

Why is a Conclusion Necessary for a Research Paper? 

The conclusion of a research paper is essential in tying together the different parts of the paper and offering a final perspective on the topic. It reinforces the main idea or argument presented and summarizes the key points and findings of the research, highlighting its significance. 

Additionally, the conclusion creates a full circle of the research by connecting back to the thesis statement presented at the paper’s beginning. It provides an opportunity to showcase the writer’s critical thinking skills by demonstrating how the research supports the main argument.

The conclusion is essential for a research paper because it provides closure for the reader. It serves as a final destination that helps the reader understand how all the different pieces of information fit together to support the main argument presented. It also offers insights into how the research can inform future studies and contribute to the larger academic discourse.

It also ensures that the reader does not get lost in the vast amount of information presented in the paper by providing a concise and coherent summary of the entire research. Additionally, it helps the reader identify the paper’s main takeaway and understand how the research contributes to the larger body of knowledge in the field.

Leave a Lasting Impression

A well-crafted conclusion is an essential element of any research paper. Its purpose is to leave a lasting impression on the reader and tie together the different parts of the paper.

To achieve this goal, a conclusion should summarize the main points and highlight the key findings of the research. By doing so, the reader can easily understand the focus and significance of the study.

A strong conclusion should also discuss any important findings that can be applied in the real world. This practical perspective gives readers a better sense of the impact and relevance of the research.

Summarize Your Thoughts

The conclusion of a research paper should be concise and provide a summary of the writer’s thoughts and ideas about the research. 

It should go beyond simply restating the main points and findings and address the “so what” of the research by explaining how it contributes to the existing body of knowledge on the same topic. This way, the conclusion can give readers a better understanding of the research’s significance and relevance to the broader academic community.

Demonstrate How Important Your Idea Is

Moving beyond a superficial overview and delving into the research in-depth is crucial to create a compelling conclusion. This entails summarizing the key findings of the study, highlighting its main contributions to the field, and placing the results in a broader context. Additionally, it would help if you comprehensively analyzed your work and its implications, underscoring its value to the broader academic community. 

New Insights

The conclusion section of a research paper offers an opportunity for the writer to present new insights and approaches to addressing the research problem.

Whether the research outcome is positive or negative, the conclusion provides a platform to discuss practical implications beyond the scope of the research paper. This discussion can help readers understand the potential impact of the research on the broader field and its significance for future research endeavors.

How to Write a Killer Conclusion with Key Points

When writing a conclusion for a research paper, it is important to cover several key points to create a solid and effective conclusion.

Restate the Thesis

When crafting a conclusion, restating the thesis statement is an important step that reminds readers of the research paper’s central focus. However, it should not be a verbatim repetition of the introduction. 

By restating the thesis concisely and clearly, you can effectively tie together the main ideas discussed in the body of the paper and emphasize the significance of the research question. However, keep in mind that the restated thesis should capture the essence of the paper and leave the reader with a clear understanding of the main topic and its importance.

Summarize the Main Points

To write an impactful conclusion, summarizing the main points discussed in the body of the paper is essential. This final section provides the writer with a last opportunity to highlight the significance of their research findings. 

However, it is equally important to avoid reiterating information already discussed in the body of the paper. Instead, you should synthesize and summarize the most significant points to emphasize the key findings. By doing so, the conclusion can effectively tie together the research findings and provide a clear understanding of the importance of the research topic.

Discuss the Results or Findings

The next step is to discuss the results or findings of the research. The discussion of the results or findings should not simply be a repetition of the information presented in the body of the paper.

Instead, it should provide a more in-depth analysis of the significance of the findings. This can involve explaining why the findings are important, what they mean in the context of the research question, and how they contribute to the field or area of study. 

Additionally, it’s crucial to address any limitations or weaknesses of the study in this section. This can provide a more balanced and nuanced understanding of the research and its implications. By doing so, the reader will have a better understanding of the scope and context of the study, which can ultimately enhance the credibility and validity of the research.

Ruminate on Your Thoughts

The final step to crafting an effective conclusion is to ruminate on your thoughts. This provides an opportunity to reflect on the meaning of the research and leaves the reader with something to ponder. Remember, the concluding paragraph should not introduce new information but rather summarize and reflect on the critical points made in the paper.

Furthermore, the conclusion should be integrated into the paper rather than presented as a separate section. It should provide a concise overview of the main findings and suggest avenues for further research.

Different Types of Conclusions 

There are various types of conclusions that can be employed to conclude a research paper effectively, depending on the research questions and topic being investigated.

Summarizing

Summarizing conclusions are frequently used to wrap up a research paper effectively. They restate the thesis statement and provide a brief overview of the main findings and outcomes of the research. This type of conclusion serves as a reminder to the reader of the key points discussed throughout the paper and emphasizes the significance of the research topic.

To be effective, summarizing conclusions should be concise and to the point, avoiding any new information not previously discussed in the body of the paper. Moreover, they are particularly useful when there is a clear and direct answer to the research question. This allows you to summarize your findings succinctly and leave the reader with a clear understanding of the implications of the research.

Externalizing

On the opposite end of the spectrum are externalizing conclusions. Unlike summarizing conclusions, externalizing conclusions introduce new ideas that may not be directly related to the research findings. This type of conclusion can be beneficial because it broadens the scope of the research topic and can lead to new insights and directions for future research.

By presenting new ideas, externalizing conclusions can challenge conventional thinking in the field and open up new avenues for exploration. This approach is instrumental in fields where research is ongoing, and new ideas and approaches are constantly being developed.

Editorial conclusions are a type of conclusion that allows the writer to express their commentary on the research findings. They can be particularly effective in connecting the writer’s insights with the research conducted and can offer a unique perspective on the research topic. Adding a personal touch to the conclusion can help engage the reader and leave a lasting impression.

Remember that regardless of the type of conclusion you choose, it should always start with a clear and concise restatement of the thesis statement, followed by a summary of the main findings in the body paragraphs. The first sentence of the conclusion should be impactful and attention-grabbing to make a strong impression on the reader.

What to Avoid in Your Conclusion

When crafting your conclusion, it’s essential to keep in mind several key points to ensure that it is effective and well-received by your audience:

• Avoid introducing new ideas or topics that have not been covered in the body of your paper.
• Refrain from simply restating what has already been said in your paper without adding new insights or analysis.
• Do not apologize for any shortcomings or limitations of your research, as this can undermine the importance of your findings.
• Avoid using overly emotional or flowery language, as it can detract from the professionalism and objectivity of the research.
• Lastly, avoid any examples of plagiarism. Be sure to properly cite any sources you have used in your research and writing.

Example of a Bad Conclusion

• Recapitulation without Insight: In conclusion, this paper has discussed the importance of exercise for physical and mental health. We hope this paper has been helpful to you and encourages you to start exercising today.
• Introduction of New Ideas: In conclusion, we have discussed the benefits of exercise and how it can improve physical and mental health. Additionally, we have highlighted the benefits of a plant-based diet and the importance of getting enough sleep for overall well-being.
• Emotional Language: In conclusion, exercise is good for your body and mind, and you should definitely start working out today!

Example of a Good Conclusion

• Insights and Implications: In light of our investigation, it is evident that regular exercise is undeniably beneficial for both physical and mental well-being, especially if performed at an appropriate duration and frequency. These findings hold significant implications for public health policies and personal wellness decisions.
• Limitations and Future Directions: While our investigation has shed light on the benefits of exercise, our study is not without limitations. Future research can delve deeper into the long-term effects of exercise on mental health and explore the impact of exercise on specific populations, such as older adults or individuals with chronic health conditions.
• Call to Action: In conclusion, we urge individuals to prioritize exercise as a critical component of their daily routine. By making exercise a habit, we can reap the many benefits of a healthy and active lifestyle.

Final Thoughts 

When writing a research paper, the conclusion is one of the most crucial elements to leave a lasting impression on the reader. It should effectively summarize the research and provide valuable insights, leaving the reader with something to ponder.

To accomplish this, it is essential to include vital elements, such as restating the thesis , summarizing the main points, and discussing the findings. However, it is equally important to avoid common mistakes that can undermine the effectiveness of the conclusion, such as introducing new information or repeating the introduction. 

So to ensure that your research is of the highest quality, it’s crucial to use proper citations and conduct a thorough literature review. Additionally, it is crucial to proofread the work to eliminate any errors. 

Fortunately, there are many available resources to help you with both writing and plagiarism prevention.

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 Research Paper Conclusion Section

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).

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.

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.

Avoid These Things When Writing a Research Paper Conclusion

As you write your conclusion of research paper, there’s a list of things professional writers don’t recommend doing. Consider these issues carefully:

• Repetition of Exact Phrases
• Repetitively using the same phrases or sentences from the main body. Repetition can make your conclusion seem redundant and less engaging.
• Overly Lengthy Summaries
• Providing excessively detailed summaries of each section of your paper. Readers may lose interest if the conclusion becomes too long and detailed.
• Unclear Connection to the Introduction
• Failing to connect the conclusion back to the introduction. A lack of continuity may make the paper feel disjointed.
• Adding New Arguments or Ideas
• Introducing new arguments or ideas that were not addressed in the body. This can confuse the reader and disrupt the coherence of your paper.
• Overuse of Complex Jargon
• Using excessively complex or technical language without clarification. Clear communication is essential in the conclusion, ensuring broad understanding.
• Apologizing or Undermining Confidence
• Apologizing for limitations or expressing doubt about your work. Maintain a confident tone; if limitations exist, present them objectively without undermining your research.
• Sweeping Generalizations
• Making overly broad or unsupported generalizations. Such statements can weaken the credibility of your conclusion.
• Neglecting the Significance
• Failing to emphasize the broader significance of your research. Readers need to understand why your findings matter in a larger context.
• Abrupt Endings
• Concluding abruptly without a strong closing statement. A powerful ending leaves a lasting impression; avoid a sudden or weak conclusion.

In reality, this is often one of the most difficult sections of a research paper to write, since you have to neatly tie up pages and pages of research in a short amount of time. To help you with this, we’ve put together some instructions and tips on how to write a research paper conclusion. We’ll also talk about what conclusions are, why they’re important, and different ways you can format them. Key Takeaways Research paper conclusions serve to close the argument the introduction opened and restate the main points of the research paper. There are three research paper conclusion formats: summarization, reflective, and projective. Your research paper conclusion should be concise, straightforward, and accurate.

Many students understand that the conclusion is a crucial part of their research paper, but they don’t know how to go about writing one.

Follow the steps below for how to write a research paper conclusion.

Open With The Research Topic. To begin a conclusion paragraph, use the first sentence to reiterate the comprehensive subject matter that your paper covered. Since this is just a sentence-long retelling of your research topic and why it’s important, it doesn’t have to be specific, but it does need clarity.

Dragonflies are a magnificently complex insect whose advanced physical mechanics and vast species differences make them a notable study in the scientific community.

Focus On Your Specific Thesis. Every research paper focuses on targetted intricacies within a larger topic. Now that the more extensive topic of the research paper has been mentioned, the next sentence or two highlights the specific thesis presented.

Don’t merely copy and paste the introduction of your thesis from the first paragraph. Restate it in different words that illicit a more in-depth understanding from the reader .

The overall characteristics found only within the Odonata family unites the dragonfly under a singular title. All species of dragonfly faced the same path towards the modern structure known today, and therefore, they are all similar in one way or another. However, there are also significant differences apparent to the naked eye between a species that shares so much of the same structure.

Summarize And Connect Main Points. Throughout a research paper, the writer presents points to support the initial thesis claim. Very briefly summarize and tie together these points in a way that supports your thesis. This is the place to restate your research findings.

By examining the striped meadowhawk and migrant hawker dragonflies, it is shown that habitat governs many aspects pertaining to that specific species’ lifestyle. It is also proven that color and patterns perceived on this insect serve a greater purpose of individualizing and distinguishing between these two species.

Bring It All Together. It sounds redundant to say you need to conclude your conclusion, but that’s the final step. You’ve done the mini recap of your research paper through the beginning sentences of your essay. Close the conclusion by making a final encouragement for an action, idea, or fact.

The dragonfly is a unique insect with uniting factors and specialization. However, the most attributed aspect to this insect as a whole is the enormity of their differences. The evolved genetic features attributed to various species of dragonflies both individualize them and apply unification to the insect as a whole.

6 Tips for Writing a Research Paper Conclusion

Consider What Conclusion Format To Use Carefully. The way you structure a conclusion has a massive effect on how impactful it will be to a reader.

Some types of writing can work well with a variety of conclusion formats, but others will confuse a paper’s message. For example, using a reflective style conclusion on a scientific research paper comes across as too opinion-based for a topic that’s shrouded in measurable fact.

Don’t Make It Too Complex. It’s best to use plain language when summarizing the information presented in a research paper or making a claim. Many students are tempted to use impressive wording and complex writing in a research paper conclusion to present themselves as experts in the subject , but it only gives the reader a headache.

Conclusions Should Be Concise . Research papers give the writer pages of leeway to make all the drawn-out points that they need, but conclusions don’t offer as much room. An essay’s conclusion needs to be short by definition because it’s merely a last takeaway for the reader. A research paper conclusion is a final paragraph, not the entire page .

Double Check Your Information. There’s nothing worse for a research paper’s validity than confidently making a claim in the conclusion that turns out to be false. It’s fundamental that all the facts and information your detail in a research paper are backed up with credible sources listed neatly on the works cited page.

Empathize With The Reader. Whether you’re submitting a research paper for an introductory university class or publishing a scholarly journal, you still need to keep the reader in mind when writing a conclusion. Think about who you’re communicating with through your research paper and what you’re hoping to accomplish with it.

Do Research . One way to fix the problem if you’re unsure of what makes an essay conclusion compelling is researching the topic. Reading articles (like this one) is helpful because they give you a clear demonstration of how to create a conclusion, but applying this structure to your own work can be difficult. A case of easier said than done.

Different Formats of Research Paper Conclusions

Based on the goal or subject of your research paper, the structure of your conclusion changes. Pick a type of conclusion that will strengthen the point of your essay. Below are examples of different formats to use when writing research paper conclusions.

Summarization. The summarization conclusion is most commonly used for research papers that are presenting a series of concrete facts.

It’s the form of conclusion that most people are familiar with. Using the summary technique requires a succinct compiling of the most critical points you’ve made in an essay.

Summarization Conclusion Formatting Works Best For:

Solution-Based Research

Persuasive Writing

History and Science Studies

Structuring An Argument

Reflective. A conclusion that uses a reflective structure takes the information outlined in the research paper to arrive at a grander insight about the topic at hand. This type of conclusion is popular when you’re attempting to change the reader’s viewpoint with a paper.

Reflective Conclusion Formatting Works Best For:

Persuasive Essays

English and Political Studies

Projective. When using a projective conclusion, the writer applies their work presented earlier in the thesis to eventual outcomes that can arise. It is called a projective conclusion because it is more results-based than summarizing facts or establishing an overarching lesson.

Projective Conclusion Formatting Works Best For:

Research Paper

Expository Essay

Narrative Works (Sometimes)

What Is the Conclusion of a Research Paper?

The conclusion of a research paper ties together all the prior information you’ve covered. It leaves the reader with a final thought about the research paper and the message it’s trying to convey.

Unlike the body paragraphs of a research paper, which aim at specificity and focus on developing a single concept or piece of information, conclusions are broader. The goal is to gloss over what’s already been stated earlier in the essay to solidify it with the reader.

The conclusion also serves a different purpose than the introduction . An introductory paragraph is for establishing what the reader will be learning more about. It opens the metaphorical door towards understanding a research endeavor or topic. The conclusion closes the argument that the introductory paragraph opens.

Why Is Writing a Conclusion Important for a Research Paper?

Including a conclusion is an important part of writing a research paper because it creates an organized summarization of information and outlines inferences about the subject studied. It provides an additional layer of clarity in a short written work.

Research papers are often lengthy and dull, so it’s easy for a reader’s attention to stray. A conclusion brings the reader back and offers them the most critical takeaways from the paper.

Research Paper Conclusion FAQ

How long should a good conclusion be?

A good conclusion should be one paragraph or three to five sentences long. Your research paper conclusion should be concise, which means you don’t need to take up a whole page for just your conclusion. Instead, try to stick to about one paragraph in length.

What are the general rules in crafting conclusions in your research paper?

The general rules for crafting conclusions for your research paper include:

Choose the right conclusion format.

Keep it simple.

Be concise.

Be accurate.

Keep the reader’s needs (or requirements) in mind.

Remind the reader of your thesis.

Summarize and connect main points.

End with a concluding sentence.

What is a better way to say, “In conclusion”?

A better way to say, “In conclusion,” is “Therefore,” “Finally,” or “Lastly.” Other good words include, “As expressed” or “As a result.” You can also simply launch into your concluding paragraph if a transition isn’t needed.

Conclusions wrap up what you have been discussing in your paper. After moving from general to specific information in the introduction and body paragraphs, your conclusion should begin pulling back into more general information that restates the main points of your argument. Conclusions may also call for action or overview future possible research. The following outline may help you conclude your paper:

In a general way,

• Restate your topic and why it is important,
• Restate your thesis/claim,
• Address opposing viewpoints and explain why readers should align with your position,
• Call for action or overview future research possibilities.

Remember that once you accomplish these tasks, unless otherwise directed by your instructor, you are finished. Done. Complete. Don't try to bring in new points or end with a whiz bang(!) conclusion or try to solve world hunger in the final sentence of your conclusion. Simplicity is best for a clear, convincing message.

The preacher's maxim is one of the most effective formulas to follow for argument papers:

Tell what you're going to tell them (introduction).

Tell them (body).

Tell them what you told them (conclusion).

In this paper, a modification of g-C 3 N 4 was carried out by combining non-metal doping with the construction of heterojunctions, and a type II heterojunction composite, S/g-C 3 N 4 @β-Bi 2 O 3 , was prepared. The phase structure, morphology, elemental composition, valence band structure, and light absorption performance of the photocatalyst were analyzed using characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and UV–vis diffuse reflectance spectroscopy (UV–vis DRS). The performance of the composite photocatalyst in the photocatalytic degradation of gaseous toluene, one of the typical volatile organic compounds (VOCs), under simulated solar light was studied. The effects of preparation conditions, toluene concentration, and recycling on the photocatalytic performance of the composite photocatalyst were investigated. The results show that under the optimal preparation conditions, S/g-C 3 N 4 @β-Bi 2 O 3 achieved a degradation efficiency of 74.0% for 5 ppm toluene after 5 h of light irradiation. Although the degradation efficiency decreased to 61.2% after five cycles, it maintained 83% of its initial activity, indicating good stability of the composite photocatalyst. Free radical quenching experiments demonstrated that h + was the main active species in the photocatalytic degradation of toluene, followed by ·O 2 − . Based on all experimental results, the migration law of photo-generated charges was analyzed, and a possible photocatalytic mechanism was proposed. In this study, a new material was obtained for the photocatalytic removal of VOCs by improving the photocatalytic properties of g-C 3 N 4 .
