Introductions and Conclusions

A speech has two moments listeners remember with unfair accuracy: the moment you started and the moment you stopped. Everything in between gets filtered through both. An introduction is not a warm-up lap — it is a working part of the speech with five specific jobs to finish, usually in well under a minute. A conclusion is not a place to trail off with “so, yeah, that’s my speech.” It is the last thing anyone carries out of the room, and sometimes the only sentence anyone repeats afterward. This chapter treats both as craft you can practice rather than personality you either have or lack. You will build attention-getters from a menu, write the relevance link that answers a listener’s silent “why am I hearing this,” establish credibility without bragging, hand off cleanly to your first main point, and close with a clincher that echoes your opening instead of apologizing for it. Weak drafts and repaired drafts sit side by side throughout, because seeing the difference teaches this faster than any rule.

Section 1What the First Ninety Seconds Have to Do

Your audience is deciding something before you reach your point

Walk into any classroom five seconds before a speech starts and watch the room. People are finishing texts, unwrapping food, resettling in chairs. They are not hostile. They are simply not yet spending anything on you. The introduction is the transaction in which they decide how much attention this is worth, and unlike a reader, they cannot go back and re-decide later at their leisure.

Psychology gives us some support here, though less than most public-speaking textbooks claim, and it is worth being precise about the difference. Nalini Ambady and Robert Rosenthal showed in the early 1990s that observers watching thirty seconds of silent video of a teacher produced ratings that correlated respectably with that teacher’s end-of-semester evaluations from actual students. That is a striking finding about how quickly impressions form. It is not a finding about speeches, and the broader “thin slices” literature has taken its share of replication scrutiny along with the rest of social psychology. Janine Willis and Alexander Todorov later found that people generate trait judgments from a face after roughly a tenth of a second of exposure — again, faces, not arguments.

So resist the confident classroom claim that “your audience judges you in the first seven seconds and never changes its mind.” The honest version is more useful anyway: impressions form fast, they are somewhat sticky, and they are revisable but only at a cost. A rocky opening does not doom you. It just means you spend the next two minutes buying back attention you could have had for free.

The five jobs

An introduction that does its work accomplishes five things, usually in this order. Order can be bent — a credibility statement sometimes hides inside the attention-getter — but nothing on this list can simply be skipped without a cost that shows up later in the speech.

Read the right-hand column again, because that is the real argument of this chapter. Every skipped job does not vanish; it becomes a tax paid somewhere later. Skip relevance and you will find yourself arguing for the importance of your topic in the middle of point two, where it interrupts the content. Skip the preview and your carefully written transitions will sound like the speaker wandering. The introduction is cheap real estate for work that is expensive everywhere else.

How long is an introduction, actually

The common guideline is ten to fifteen percent of total speaking time for the introduction and five to ten percent for the conclusion. Treat those numbers as a sanity check, not a law — they are a teaching convention rather than a research finding. What they usefully prevent is the two failure modes instructors actually see: the ninety-second speech with a three-minute introduction, and the eight-minute speech that begins with “okay, so, my topic is diabetes” and is into point one before anyone has looked up.

Run the arithmetic once and keep the numbers. A two-minute speech gets an introduction of twelve to eighteen seconds and a conclusion of six to twelve — one vivid sentence, a thesis, a three-word preview, and no credibility statement unless it is four words long. A five-minute speech gets thirty to forty-five seconds up front and fifteen to thirty at the close, which at Chapter 6’s planning rate of about 130 words a minute is roughly 65 to 100 spoken words for all five jobs with none of them padded. An eight- to ten-minute speech can afford forty-eight to ninety seconds of introduction, enough for a real story, and twenty-four to sixty seconds for a two-part ending. Past twenty minutes you are into two or three minutes of opening, and you should add an agenda, a housekeeping line about when questions are welcome, and a fuller summary at the end.

Time your draft introduction out loud with a stopwatch, not by counting words in your head. Almost everyone reads faster silently than they speak, and almost every first draft of an introduction runs long. If a five-minute speech opens with seventy seconds of throat-clearing, you have spent nearly a quarter of your speech before making a single point.

Section 2Openings That Earn Attention

The menu

You do not have to be witty on demand. You have to choose a device and execute it. Here is the working menu, with the failure mode of each attached, because every one of these can be done badly.

The story or anecdote. The strongest general-purpose opener, because human attention follows narrative almost involuntarily. Keep it inside the budget from Section 1 — about twenty seconds in a five-minute speech, up to forty-five in a long one — put one specific human being in it, and use present-tense detail. It fails when it is a summary of a story rather than the story itself. The startling statistic. Powerful when the number is genuinely surprising and correctly sourced; inert when the number is one everybody already knows. It fails when you deliver four statistics in a row and the room stops hearing any of them. The question. Effective when it is either answerable by a show of hands or genuinely uncomfortable to answer privately. It fails when it is the empty rhetorical form — “Have you ever thought about how important communication is?” — which asks nothing and receives nothing.

The quotation. Works when it is short, unfamiliar, and from someone the audience has reason to respect. It fails when it is a famous line everyone has heard, when it is longer than two sentences, or when it is unverified. The demonstration or object. Holding up the actual thing you are talking about beats describing it. It fails when the object is too small to see or when handling it eats twenty seconds of silence. The reference to the occasion, audience, or moment. The most underrated opener and the hardest to fake, because it requires you to have noticed something real about this room on this day. The contrast. Sets two facts beside each other and lets the gap between them do the arguing. It fails when the two halves are not genuinely comparable, because then the audience spends its attention resisting the pairing instead of feeling the gap. Humor. High reward, high variance, and the only item on this list that fails catastrophically rather than merely flatly. Self-directed humor is safer than humor about anyone else. If a line has not gotten a laugh from three separate people in rehearsal, it will not get one from thirty strangers.

Six openers for one topic

Take one topic — bystander CPR and public access defibrillators — and write six openers before you commit to one. Then choose on audience, not on which one you enjoyed writing.

Notice what all six share. Each is one idea, not three. Each is under twenty-five seconds spoken. None of them contains the word “today” or the phrase “I am going to talk about.” And each one points at the same thesis, which is the real test: an attention-getter that grabs the room but has nothing to do with your speech is a bait-and-switch, and audiences feel the switch even when they cannot name it.

Five openers that cost you, and their repairs

These are not stylistic preferences. Each of the five below takes something concrete away from you — credibility, time, or goodwill — and each has a mechanical fix.

One more that deserves its own note: the throat-clearing sequence. “Okay. Um. Is this on? Can everyone hear me? Great. So.” That is nine seconds and it happens to nearly every first-time speaker. The fix is not willpower, it is choreography — decide in advance that your first spoken syllable is the first word of your written opener, and rehearse the walk-up in silence so your mouth has nothing to do until you arrive.

Section 3Relevance, Credibility, and the Handoff

The relevance link is written for one audience only

A grabbing opener earns you attention. The relevance link is what converts that attention into investment. It is one or two sentences that connect your topic to something this audience already cares about: their money, their time, their safety, their family, their license, their grade, their patients.

The mistake nearly everyone makes is writing a relevance link for humanity in general. “This is an important issue that affects all of us” is not a relevance link. It is the shape of one with the content removed. The repair is always the same — name the audience and name the specific stake. Chapter 5 asked you to analyze the audience; this is the sentence where that analysis becomes visible.

Read the strong column aloud and notice how little of it is emotional language. The force comes from specificity: eleven weeks, 1,200 hours, one elevator, five in the morning. Vague urgency is weak. Concrete facts about this audience’s actual life are strong. If a sentence in your relevance link would work equally well for any other room in the country, it is not doing its job.

Credibility without bragging

Aristotle divided ethos — the persuasive force of the speaker’s character — into three components in the Rhetoric: practical good sense (phronesis), good character (arete), and goodwill toward the audience (eunoia). Twenty-four centuries later the division still works, and it is a better checklist than “say why you are qualified,” because most students have no formal qualifications, freeze at that instruction, and then drop the credibility statement altogether — which is why it is the job most often missing from a student introduction.

You almost always have one of three honest sources. Experience — you have lived it, worked it, or watched it up close. Research — you did not live it, but you spent real hours with real sources, and saying so is legitimate. Goodwill — you can demonstrate that you understand this audience’s situation and are not here to lecture them. The last one is the one students forget, though Aristotle treated all three as necessary: a room that does not believe you are on its side will not believe you on anything else either.

Keep it to one or two sentences. A credibility statement that runs four sentences stops sounding like credentials and starts sounding like insecurity. And never claim expertise you do not have; an audience that catches one inflated claim will re-examine everything else you said, which is a terrible trade for a phrase you did not need.

Thesis, preview, and the clean handoff

Your thesis was built in Chapter 6 and your main points in Chapter 8. In the introduction, both get spoken versions. The thesis is one sentence, ideally under twenty-five words, in the plainest language you own. The preview is the audible table of contents: name your two to four main points in the order you will deliver them, using the same key words you will use later. Same words matters. If you preview “recognize, respond, and retrieve” and then title your points “identification, action, and equipment,” the audience cannot tell that you kept your promise.

The last sentence of the introduction is a handoff — a transition into main point one. It is the smallest piece of the frame, and because it is not one of the five jobs it is the piece speakers most often leave out. Without it, they finish the preview and simply start talking about point one, and the seam is invisible.

Here is a complete introduction for a ten-minute informative speech, annotated line by line. Read it aloud once before you read the annotations; it is 155 words, which runs about seventy seconds at the planning rate — inside the sixty-to-ninety-second budget Section 1 gives a speech that long. For a five-minute version you would cut the story to two sentences and the credibility line to one.

A note on the accuracy of that example, because it doubles as a lesson. The study alluded to is Westbrook and colleagues’ 2010 work in the Archives of Internal Medicine, which reported that each interruption was associated with roughly a twelve percent increase in procedural failures and clinical errors. It was observational, so the speech says “associated with” and not “causes.” That single word choice is the difference between a credible introduction and one a knowledgeable listener stops trusting at second thirty.

Section 4Conclusions That Land

Three jobs, in order

Classical rhetoric called the conclusion the peroratio. The Roman handbooks split it into a summing-up and one or more closing appeals to feeling — recapitulate the argument, then move the audience one last time. Modern practice adds a job at the front, because modern audiences are not sure when you are done.

Job one: signal closure. Give an unmistakable verbal cue that the end has arrived — “So here is what I want you to take out of this room,” or “Let me bring this back to aisle six.” Something audible. The reason is practical: an audience that senses an ending pays attention differently, and an audience that cannot tell whether you are finished will sit in awkward silence when you stop. Avoid “in conclusion” if you can — not because it is wrong but because it is exhausted, and because too many speakers say it and then talk for another two minutes, which trains audiences to distrust the phrase.

Job two: restate and summarize. Restate the thesis in different words than the introduction used — same idea, fresh phrasing, so it registers as arrival rather than repetition. Then compress the main points into a single sentence. Not a re-lecture. One sentence.

Job three: the clincher. The final line. This is the sentence some people will repeat in the hallway, and it is the one place in a speech where you are allowed to be a little bit literary. Write it out. Memorize it. Say it and then stop.

A word about why the ending matters. Memory researchers since Ebbinghaus have documented the serial position curve — in list-learning experiments, items at the beginning and end are recalled better than items in the middle, an effect Bennet Murdock mapped carefully in 1962. That is real. Extending it from word lists to eight-minute speeches is an extrapolation, and honest instructors should label it as one. Separately, persuasion researchers have argued for decades about whether the first or last message in a sequence wins; work in the Hovland tradition, notably Miller and Campbell in 1959, found that it depends on the intervals between messages and between the last message and the decision. So the confident claim “people remember the last thing you say” is a reasonable working assumption, not a settled law. Write a strong ending anyway. The cost of doing so is one sentence.

Clinchers that work

Five reliable forms, each written out.

Two craft notes. First, short is strong. Look at the last words of every clincher above — hands, life, window, brain, move. Ending on a short, concrete noun or verb gives the sentence a floor to land on. Compare “and so that is why this is such an important consideration for all of us moving forward,” which ends on an abstraction wrapped in a cliche and dissolves in the air. Second, a call to action must be small enough to actually happen. “Go get certified” is a wish. “Look at the box on the wall on your way out” is an instruction someone will follow within ninety seconds.

Endings that leak

Five ways a conclusion loses the room, with repairs.

Here is one complete conclusion, weak and repaired, so you can hear the difference at full length. Weak: “So in conclusion, like I said, interruptions are a big problem and they cause errors, and there are some things you can do about it like the ones I mentioned. Um, I think it’s really important for everyone. Any questions? No? Okay. Thanks.” Repaired: “So come back to Priya, at 9:40, with the syringe in her hand and three people talking to her. She does not need a new policy. She needs one sentence — ‘give me thirty seconds’ — and the nerve to say it out loud. Interruptions are not going to stop. What can change is who is allowed to pause them. Say the sentence on your next shift. It works better than you think.”

Section 5Assembling, Testing, and Rehearsing the Frame

Write them last, memorize them first

Build the body first. Always. You cannot preview points you have not chosen, and a thesis usually shifts once you see what your evidence will actually support. Students who write the introduction first tend to fall in love with an opening line and then bend the speech to keep it, which is backwards.

Then invert the priority for memorization. Do not memorize a speech — memorized speeches sound memorized, and a forgotten line in the middle can be improvised around. Do memorize two things exactly: the first sentence and the last sentence. The first because that is when your body is at peak arousal and your working memory is at its worst; a sentence you can say in your sleep gets you moving. The last because that is the one you will otherwise fumble in relief. Twenty-five words memorized cold is a better investment than an hour of rereading your outline.

Then write both on your speaking outline in a form you cannot miss: the first sentence in full at the very top of the page, the last sentence in full at the very bottom, both in capitals or boxed. Chapter 8’s speaking outline is keywords everywhere else. These two are the exceptions.

The bookend, worked end to end

The strongest and simplest structural trick in this chapter is the bookend: open with a story or image, leave it deliberately unfinished, and finish it in the clincher. It gives you a built-in ending, it produces a satisfying sense of arrival, and it costs nothing but planning. Some instructors invoke the Zeigarnik effect — the claim that unfinished tasks stay more available in memory — to explain why; the original 1927 finding has had a mixed replication record, so treat the mechanism as plausible rather than proven. The technique works regardless of which explanation is right.

Notice that the clincher does not summarize. The summary sentence happened about twenty seconds earlier, in the restatement. The clincher is free to do the one job a summary cannot do, which is make somebody feel that the last five minutes were about them.

Score it before you deliver it

Run this rubric on your draft. Score each row 0, 1, or 2. Anything below 15 out of 20 means the frame is not ready. Then revise the two lowest rows first, because that is where the fastest gain is.

Then run three physical tests that a rubric cannot catch. The stopwatch test: deliver the introduction aloud, standing, and check that it fits the budget from Section 1. The cold-start test: without looking at anything, say your first sentence and your last sentence. If you cannot, you have not memorized them, you have merely recognized them. The stranger test: read your introduction to someone who knows nothing about your topic and ask them two questions — what is this speech going to argue, and what are the parts? If they cannot answer both, your thesis or preview is not doing its job, no matter how good it looks on paper.

When the frame changes

The five-job introduction is a classroom default and a good one, but the real world varies the recipe. What never changes is that both ends of a talk are load-bearing.

In a workplace briefing or huddle, lead with the conclusion. Busy audiences want the ask first and the reasoning second, and your role usually supplies the credibility for you: “I am asking for one change to the med-pass workflow, and it costs nothing. Here is why.” In a virtual meeting, attention is thinner and faces are small, so open faster and make the room participatory inside the first thirty seconds — “Before I share anything, put a number in the chat: how many times were you interrupted in the last hour?” With a hostile or skeptical audience, goodwill moves ahead of the thesis, because a thesis stated before you have shown you understand their position arrives as an attack: “I know what this policy costs the people who have to staff it, because I asked four of you before I wrote this.”

For impromptu remarks you have no draft, so use the three-part reflex — one opening line, one point with one example, one closing line — and decide the closing line before you start talking. “I want to say one thing about Marcus, and then I will sit down” buys you the fifteen seconds you need to find it. When a question period follows, reserve the clincher so questions cannot hijack your ending: “I will take questions for five minutes, and then I have one last thing to say before we close.” In toasts, eulogies, and ceremonial remarks, drop the preview entirely; a naked table of contents sounds bureaucratic in an emotional room, and the story and the clincher carry nearly all the weight.

Rehearse the opening more than any other passage — five to ten times aloud, standing, in the voice you will actually use — because that is the one minute you will deliver with the most adrenaline in your system and the least support from your notes. Rehearse the closing second-most, because you will deliver it while flooded with relief, which is its own kind of impairment. The middle of a speech is forgiving. The ends are not.

Words worth knowing
