How to write an excellent thesis conclusion [with examples]

Restate the thesis

Review or reiterate key points of your work, explain why your work is relevant, a take-away for the reader, more resources on writing thesis conclusions, frequently asked questions about writing an excellent thesis conclusion, related articles.

At this point in your writing, you have most likely finished your introduction and the body of your thesis, dissertation, or research paper . While this is a reason to celebrate, you should not underestimate the importance of your conclusion. The conclusion is the last thing that your reader will see, so it should be memorable.

A good conclusion will review the key points of the thesis and explain to the reader why the information is relevant, applicable, or related to the world as a whole. Make sure to dedicate enough of your writing time to the conclusion and do not put it off until the very last minute.

This article provides an effective technique for writing a conclusion adapted from Erika Eby’s The College Student's Guide to Writing a Good Research Paper: 101 Easy Tips & Tricks to Make Your Work Stand Out .

While the thesis introduction starts out with broad statements about the topic, and then narrows it down to the thesis statement , a thesis conclusion does the same in the opposite order.

• Restate the thesis.
• Review or reiterate key points of your work.
• Explain why your work is relevant.
• Include a core take-away message for the reader.

Tip: Don’t just copy and paste your thesis into your conclusion. Restate it in different words.

The best way to start a conclusion is simply by restating the thesis statement. That does not mean just copying and pasting it from the introduction, but putting it into different words.

You will need to change the structure and wording of it to avoid sounding repetitive. Also, be firm in your conclusion just as you were in the introduction. Try to avoid sounding apologetic by using phrases like "This paper has tried to show..."

The conclusion should address all the same parts as the thesis while making it clear that the reader has reached the end. You are telling the reader that your research is finished and what your findings are.

I have argued throughout this work that the point of critical mass for biopolitical immunity occurred during the Romantic period because of that era's unique combination of post-revolutionary politics and innovations in smallpox prevention. In particular, I demonstrated that the French Revolution and the discovery of vaccination in the 1790s triggered a reconsideration of the relationship between bodies and the state.

Tip: Try to reiterate points from your introduction in your thesis conclusion.

The next step is to review the main points of the thesis as a whole. Look back at the body of of your project and make a note of the key ideas. You can reword these ideas the same way you reworded your thesis statement and then incorporate that into the conclusion.

You can also repeat striking quotations or statistics, but do not use more than two. As the conclusion represents your own closing thoughts on the topic , it should mainly consist of your own words.

In addition, conclusions can contain recommendations to the reader or relevant questions that further the thesis. You should ask yourself:

• What you would ideally like to see your readers do in reaction to your paper?
• Do you want them to take a certain action or investigate further?
• Is there a bigger issue that your paper wants to draw attention to?

Also, try to reference your introduction in your conclusion. You have already taken a first step by restating your thesis. Now, check whether there are other key words, phrases or ideas that are mentioned in your introduction that fit into your conclusion. Connecting the introduction to the conclusion in this way will help readers feel satisfied.

I explored how Mary Wollstonecraft, in both her fiction and political writings, envisions an ideal medico-political state, and how other writers like William Wordsworth and Mary Shelley increasingly imagined the body politic literally, as an incorporated political collective made up of bodies whose immunity to political and medical ills was essential to a healthy state.

Tip: Make sure to explain why your thesis is relevant to your field of research.

Although you can encourage readers to question their opinions and reflect on your topic, do not leave loose ends. You should provide a sense of resolution and make sure your conclusion wraps up your argument. Make sure you explain why your thesis is relevant to your field of research and how your research intervenes within, or substantially revises, existing scholarly debates.

This project challenged conventional ideas about the relationship among Romanticism, medicine, and politics by reading the unfolding of Romantic literature and biopolitical immunity as mutual, co-productive processes. In doing so, this thesis revises the ways in which biopolitics has been theorized by insisting on the inherent connections between Romantic literature and the forms of biopower that characterize early modernity.

Tip: If you began your thesis with an anecdote or historical example, you may want to return to that in your conclusion.

End your conclusion with something memorable, such as:

• a call to action
• a recommendation
• a gesture towards future research
• a brief explanation of how the problem or idea you covered remains relevant

Ultimately, you want readers to feel more informed, or ready to act, as they read your conclusion.

Yet, the Romantic period is only the beginning of modern thought on immunity and biopolitics. Victorian writers, doctors, and politicians upheld the Romantic idea that a "healthy state" was a literal condition that could be achieved by combining politics and medicine, but augmented that idea through legislation and widespread public health measures. While many nineteenth-century efforts to improve citizens' health were successful, the fight against disease ultimately changed course in the twentieth century as global immunological threats such as SARS occupied public consciousness. Indeed, as subsequent public health events make apparent, biopolitical immunity persists as a viable concept for thinking about the relationship between medicine and politics in modernity.

The conclusion is the last thing that your reader will see, so it should be memorable. To write a great thesis conclusion you should:

The basic content of a conclusion is to review the main points from the paper. This part represents your own closing thoughts on the topic. It should mainly consist of the outcome of the research in your own words.

The length of the conclusion will depend on the length of the whole thesis. Usually, a conclusion should be around 5-7% of the overall word count.

End your conclusion with something memorable, such as a question, warning, or call to action. Depending on the topic, you can also end with a recommendation.

How to Write a Conclusion

You’ve done it. You’ve refined your introduction and your thesis. You’ve spent time researching and proving all of your supporting arguments. You’re slowly approaching the finish line of your essay and suddenly freeze up because—that’s right—it’s time to write the conclusion.

Before we dive into the details, here’s a basic outline of how to write a conclusion:

• Restate your thesis: remind readers of your main point
• Reiterate your supporting points: remind readers of your evidence or arguments
• Wrap everything up by tying it all together
• Write a clincher: with the last sentence, leave your reader with something to think about

For many, the conclusion is the most dreaded part of essay writing . Condensing all the points you’ve analyzed in a tidy little package is certainly easier said than done. How can you make a good final impression while emphasizing the significance of your findings?

• Consider the clincher

What your conclusion should not include

Learning how to write a conclusion for an essay doesn’t need to feel like climbing Everest. It is wholly possible to tie everything together while considering the broader issues and implications of your argument. You just need the right strategy.

What do you want to leave your readers with? Perhaps you want to end with a quotation that adds texture to your discussion. Or, perhaps you want to set your argument into a different, perhaps larger context. 

An effective conclusion paragraph should ultimately suggest to your reader that you’ve accomplished what you set out to prove.

5 key details for writing a conclusion

1 restate your thesis.

As you set out to write your conclusion and end your essay on an insightful note, you’ll want to start by restating your thesis. Since the thesis is the central idea of your entire essay, it’s wise to remind the reader of the purpose of your paper. 

Once you’ve restated your thesis (in a way that’s paraphrased , of course, and offers a fresh understanding), the next step is to reiterate your supporting points.

2 Reiterate supporting points

Extract all of the “main points” from each of your supporting paragraphs or individual arguments in the essay . Then, find a way to wrap up these points in a way that demonstrates the importance of the ideas. 

Depending on the length of your essay, knowing how to write a good conclusion is somewhat intuitive—you don’t want to simply summarize what you wrote. Rather, the conclusion should convey a sense of closure alongside the larger meaning and lingering possibilities of the topic. 

3 Ask yourself: “So what?” 

At some point in your life, a teacher has probably told you that the end of an essay should answer the question “So what?” or “Why does it matter?” This advice holds true. It’s helpful to ask yourself this question at the start of drafting your thesis and come back to it throughout, as it can keep you in tune with the essay’s purpose. Then, at your conclusion, you won’t be left searching for something to say.

4 Add perspective 

If you’ve come across a fantastic quote in your research that didn’t quite make it into the essay, the conclusion is a great spot for it. Including a quote from one of your primary or secondary sources can frame your thesis or final thoughts in a different light. This can add specificity and texture to your overall argument. 

For example, if you’ve written an essay about J.D. Salinger’s Catcher in the Rye, you can think about using a quote from the book itself or from a critic or scholar who complicates your main point. If your thesis is about Salinger’s desire to preserve childhood innocence, ending with a biographer’s statement about Salinger’s attitude toward his own youth might be illuminating for readers. If you decide to amplify your conclusion paragraph in this way, make sure the secondary material adds (and not detracts) from the points you already made. After all, you want to have the last word!

5 Consider the clincher

At the very end of the essay comes your closing sentence or clincher. As you think about how to write a good conclusion, the clincher must be top of mind. What can you say to propel the reader to a new view on the subject? This final sentence needs to help readers feel a sense of closure. It should also end on a positive note, so your audience feels glad they read your paper and that they learned something worthwhile. 

There are a few things that you should definitely strive to avoid when writing your conclusion paragraph. These elements will only cheapen your overall argument and belabor the obvious.

Here are several conclusion mishaps to consider:

• Avoid phrases like “in summary,” “in conclusion,” or “to sum up.” Readers know they’re at the end of the essay and don’t need a signpost. 
• Don’t simply summarize what’s come before. For a short essay, you certainly don’t need to reiterate all of your supporting arguments. Readers will know if you just copied and pasted from elsewhere.
• Avoid introducing brand new ideas or evidence. This will only confuse readers and sap force from your arguments. If there’s a really profound point that you’ve reached in your conclusion and want to include, try moving it to one of your supporting paragraphs. 

Whereas your introduction acts as a bridge that transfers your readers from their own lives into the “space” of your argument or analysis, your conclusion should help readers transition back to their daily lives. 

By following this useful roadmap, you can feel confident that you know how to write a good conclusion that leaves readers with a solution, a call to action, or a powerful insight for further study.

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.”)

Writing the conclusion

The conclusion of your thesis, whether embedded in or separated from your discussion chapter, should create a strong closure to your thesis as it leads out to future research and pathways.

Key conclusion moves

• Summarise the research by restating the research problem and aim, providing a succinct answer to these, and recapping the key findings and evidence
• Unpack the implications of your contribution for theory, practice, research and/or policy in the field
• Acknowledge the limitations and scope of your research
• Address the next frontier: ‘what’s next?’ - make specific recommendations for future work in the field: what could be done to apply or further your research?

Depending on your discipline, you could include a section reflecting on your professional learning as a researcher through the study, especially if you started the thesis with a personal anecdote. Keep your conclusion  concise – it could be just several pages long.

Compare the differences between discussions and conclusions in the table below:

Gather ideas for the conclusion

As you write or edit  your thesis, gather in one place ideas that don’t quite fit the tight purpose of an earlier chapter, or ideas that you would love to develop in another project. These can provide fresh material for the conclusion. For example, they can become statements about the social implications of your research or your recommendations for future investigations.

Align the conclusion with earlier parts of thesis

The introduction and conclusion, as well as the mini-introductions and mini-conclusions of the core chapters, form the bulk of a thesis narrative as they give readers a holistic perspective of the research.

To align the conclusion:

• Make sure it addresses the same problem you set out in the introduction
• If an anecdote or another kind of hook has been used to start the introduction, think about ending the thesis with a return to the hook
• Assess whether you need to adjust the introduction or earlier parts of the thesis to fit your conclusions, or whether the conclusions themselves need to be adjusted.

Explore example introductions and conclusions

In this activity, you’ll read short introduction and conclusion excerpts from two example theses. As you read, think about the ways the author has linked or connected their conclusions to their introductions. Then, turn each card to read a brief commentary.
