What are the benefits of a strong conclusion?

“OK, I’m done; thank God that’s over!” Or, “Thanks. Now what? Do I just sit down?” It’s understandable to feel relief as you end your speech, but remember that as a speaker, your conclusion is the last chance you have to drive home your ideas. When you opt to end the speech with an ineffective conclusion—or no conclusion at all—your speech loses the energy you created, and the audience is left confused and disappointed. Just as a good introduction helps bring an audience into your speech’s world, and a good speech body holds the audience in that world, a good conclusion helps bring that audience back to reality. So, plan ahead to ensure that your conclusion is an effective one. While a good conclusion will not rescue a poorly prepared speech, a strong conclusion signals to your listeners that the speech is over and helps them remember your topic. Now, let’s examine the functions fulfilled by a speech conclusion.

Signals the End

The first function of a good conclusion is to signal the speech’s end. You may be thinking that telling an audience that you’re about to stop speaking is a “no brainer,” but many speakers really don’t prepare their audience to conclude. When a speaker just suddenly stops speaking, the audience is left confused and disappointed. Instead, make sure that you leave your audience knowledgeable and satisfied.

Aids Audience’s Memory

The second function of a good conclusion stems from some very interesting research reported by the German psychologist Hermann Ebbinghaus in his 1885 book Memory: A Contribution to Experimental Psychology (Ebbinghaus, 1885). Ebbinghaus proposed that humans remember information in a linear fashion, which he calls the serial position effect. He found that an individual’s ability to remember information in a list, such as a grocery list, a chores list, or a to-do list depends on the item’s location on the list. Specifically, he found that items toward the list’s beginning and items toward the list’s end tended to have the highest recall rates. In Ebbinghaus’ serial position effect, he calls information at the list’s beginning—primacy, and information at the list’s end—recency, and shows that information in these positions are easier to recall than information in the list’s middle.

So, what does this serial position effect have to do with speech conclusions? A lot! Ray Ehrensberger wanted to test Ebbinghaus’ serial position effect in public speaking. Ehrensberger created an experiment that rearranged a speech topic’s order to determine the audience’s information recall (Ehrensberger, 1945). Ehrensberger’s study reaffirmed primacy and recency’s importance when listening to speeches. In fact, Ehrensberger found that the information delivered during a speech conclusion—recency, had the highest recall level overall.

What should I include in a strong conclusion?

A strong conclusion restates the thesis, reviews the main points, and uses a concluding device.

Restate the Thesis

The first step in a powerful conclusion is to restate your thesis statement. When you restate the thesis statement as you conclude, you’re re-emphasizing your speech’s overarching main idea. For example, suppose your thesis statement is, “I will analyze how Barack Obama uses lyricism in his July 2008 speech, ‘A World That Stands as One.’” At the conclusion, restate the thesis in this fashion: “In the past few minutes, I have analyzed how Barack Obama uses lyricism in his July 2008 speech, ‘A World That Stands as One.’” Notice the shift in tense: the statement has gone from the future tense—this is what I will speak about, to the past tense—this is what I have spoken about. Restating the thesis in your conclusion reminds the audience of your speech’s major purpose or goal, helping them to better remember it.

Review the Main Points

The second step in a powerful conclusion is to review the main points after restating the speech’s thesis. A big differences between written and oral communication is oral communication’s need to repeat. So, you increase the likelihood that the audience retains your main points after the speech is over when you do the following: preview your main points in the introduction, effectively discuss and make transitions to your main points during the speech’s body, and finally, review your main points in the conclusion,

In a speech’s introduction, deliver a preview of the main body points, and in the conclusion, deliver a review. Let’s look at a sample preview:

To understand the gender and communication field, I will first differentiate between the terms biological sex and gender. I will then explain gender research in communication’s history. Lastly, I will examine some important findings related to gender and communication.

In this preview, you have three clear main points. Let’s see how you can review them at your speech’s conclusion:

Today, we have differentiated between the terms biological sex and gender, examined gender research in communication’s history, and analyzed some topic research findings.

In the past few minutes, I have explained the difference between the terms biological sex and gender, discussed the communication field’s rise in gender research, and examined some groundbreaking topic studies.

Notice that both conclusions review the main points originally set forth. Both variations are equally effective main point reviews, but you might like the linguistic turn of one over the other. Remember, while there is a lot of science to help us understand public speaking, there’s a lot of art as well, so you are always encouraged to choose the wording that you think is most effective for your audience.

Concluding Devices

The final step in a powerful conclusion is to employ a concluding device. A concluding device is essentially the final thought you want to impart to your audience when you stop speaking. It also provides a definitive sense of closure to your speech. Just as a gymnast dismounting the parallel bars or balance beam wants to stick the landing and avoid taking two or three additional steps, a speaker wants to stick their speech ending with a concluding device instead of with, “Well, umm, I guess I’m done.” Miller observed that speakers tend to use one of ten concluding devices when ending a speech (Miller, 1946). Let’s examine these ten concluding devices.

Conclude with a Challenge

The first way to conclude a speech is with a challenge. A challenge is a call to engage in some kind of activity that requires a contest or special effort. In a speech on fund raising’s necessity, conclude by challenging the audience to raise 10 percent more than their original projections. Audience members are being asked to go out of their way to do something different that involves their effort.

Conclude with a Quotation

The second way to conclude a speech is by reciting a quotation relevant to the speech topic. When using a quotation, think about whether your goal is to end on a persuasive note or an informative note. Some quotations will have a clear call-to-action, while other quotations summarize or provoke thought. For example, let’s say you are delivering an informative speech about dissident writers in the former Soviet Union. End by citing this quotation from Alexander Solzhenitsyn: “A great writer is, so to speak, a second government in his country. And for that reason, no regime has ever loved great writers” (Solzhenitsyn, 1964). Notice that this quotation underscores the writers-as-dissidents idea, but it doesn’t ask listeners to put forth effort to engage in any specific thought process or behavior. If, on the other hand, you are delivering a persuasive speech urging your audience to participate in a very risky political demonstration, use this quotation from Martin Luther King Jr.: “If a man hasn’t discovered something that he will die for, he isn’t fit to live” (King, 1963). In this case, the quotation leaves the audience with these messages: that great risks are worth taking, that they make our lives worthwhile, and that the right thing to do is to take that great risk.

Conclude with a Summary

The third way to conclude a speech is to end with a summary. To do this, the speaker simply elongates the main point’s review. While this may not be the most exciting concluding device, it can be useful for information that is highly technical or complex or for speeches that last longer than thirty minutes. Typically, for short speeches, such as student-given speeches, avoid this summary device.

Conclude by Visualizing the Future

The fourth way to conclude a speech is to visualize the future. This device helps your audience imagine the future that you believe can occur. For example, if you are giving a speech on developing video games for learning, conclude by inviting your audience to visualize a future classroom where video games are perceived as true learning tools and how those tools are used. More often, speakers use future visualization to depict how society would be, or how an individual listener’s life would be different, if the speaker’s persuasive attempts work. For example, if in your speech you propose that hiring more public-school reading specialists will solve illiteracy, ask your audience to imagine a world without illiteracy. In using this visual, your goal is to persuade your audience to adopt your view point. By showing that your future vision is a positive one, this conclusion further persuades your audience to help create this future.

Conclude with an Appeal-for-Action

The fifth way to conclude a speech, and probably the most common persuasive device, is the appeal-for-action or the call-to-action. In essence, the appeal-for-action occurs when a speaker asks her or his audience to engage in a specific behavior or to change their thinking. When a speaker concludes by asking the audience “to do” or “to think” in a specific manner, the speaker wants to see an actual change. Whether the speaker appeals for people to eat more fruit, buy a car, vote for a candidate, oppose the death penalty, or sing more in the shower, the speaker is asking the audience to engage in action.

One specific appeal type is the immediate call-to-action. Whereas some appeals ask for people to engage in future behavior, the immediate call-to-action asks people to engage in behavior right now. If a speaker wants to see a new traffic light placed at a dangerous intersection, he or she may conclude by asking all the audience members to sign a digital petition right then and there, using a computer the speaker has made available. Here are more immediate call-to-action examples:

• In a speech on eating more vegetables, pass out raw veggies and dip at the speech conclusion.
• In a speech on petitioning a lawmaker for a new law, provide audience members with a prewritten email they can send to the lawmaker.
• In a speech on hand sanitizer’s importance, pass out little hand sanitizer bottles and show audience members how to correctly apply the sanitizer.
• In a speech on charity donations, send a box around the room asking for donations.

These are just a few different examples we’ve actually seen students use to elicit an immediate change in behavior. The immediate call-to-action may not lead to long-term change, but can be very effective at increasing the likelihood that an audience will change behavior in the short term.

Conclude by Inspiration

The sixth way to conclude a speech is to inspire someone. By definition, the word inspire means to affect or arouse someone. Both affect and arouse have strong emotional connotations. The ultimate goal of employing an inspirational concluding device is similar to an appeal-for-action, but the ultimate goal is more lofty or ambiguous—the goal is to stir someone’s emotions in a specific manner. Maybe a speaker is giving an informative speech on domestic violence’s prevalence in our society today. That speaker could end the speech by reading Paulette Kelly’s powerful poem, “I Got Flowers Today,” which is a poem that evokes strong emotions because it’s about an abuse victim who receives flowers from her abuser every time she is victimized. The poem ends by saying, “I got flowers today… / Today was a special day—it was the day of my funeral / Last night he killed me” (Kelly, 1994).

Conclude with Advice

The seventh way to conclude a speech is to end with your advice. This concluding device is one that should be used primarily by speakers who are recognized as expert authorities on a given subject. Advice is essentially a speaker’s opinion about what should or should not be done. The problem with opinions is that everyone has one; and one person’s opinion is not necessarily any more correct than another’s. There must be a really good reason your opinion—and therefore your advice—should matter to your audience. If, for example, you are a nuclear physics expert, conclude an energy speech by giving advice about nuclear energy’s benefits.

Conclude by Proposing a Solution

The eighth way to conclude a speech is to offer a powerful solution to the problem discussed within your speech. For example, perhaps you have been discussing the problems associated with art education’s disappearance in the United States. Propose a solution to create more community-based art experiences for school children as a way to fill this gap. Although this can be an effective conclusion, consider discussing the solution in more depth as a stand-alone main point within the speech’s body so that you can address your audience’s concerns about the proposed solution.

Conclude with a Question

The nineth way to conclude a speech is to ask a rhetorical question that forces the audience to ponder an idea. Maybe you are giving a speech on the environment’s importance, so you end the speech by saying, “Think about your children’s future. What kind of world do you want them raised in? A world that is clean, vibrant, and beautiful—or one that is filled with smog, pollution, filth, and disease?” Notice that you aren’t actually asking the audience to verbally or nonverbally answer the question—the question’s goal is to force the audience into thinking about what kind of world they want for their children.

Conclude with a Reference to Your Audience

The tenth way to conclude a speech is to refer to your audience. As discussed by Miller (1946), this concluding device is useful when a speaker attempts to answer a basic question for the audience, such as, “What’s in it for me?” The goal of this concluding device is to spell out the direct benefits a behavior or thought-change has for audience members. For example, a speaker talking about stress reduction techniques concludes by clearly listing all the physical health benefits that stress reduction offers, such as improved reflexes, improved immune system, improved hearing, and lowered blood pressure. In this case, the speaker is clearly spelling out why audience members should care—so what? What’s in it for me!
