How to Give a Talk, Start to Stop

The lights go down "so the slides show up better". The speaker drifts to the far side of the stage, laser pointer circling slide eighty... the first of ten conclusion slides. Somebody up front is reading email.

Talent has very little to do with fixing that room. Speaking quality gets written as Q = f(K, P, t)- knowledge, practice and talent, with the t drawn small on purpose.

How to Start, and Not With a Joke

A joke in the first minute falls flat- people are still putting laptops away and tuning in to a new voice. Open with an empowerment promise: what the room will know by the end that it didn't know at the start.

Ask for laptops and phones closed. A 2013 study in Computers & Education found students multitasking on a laptop during a lecture scored lower... so did the students who could merely see that screen.

Keeping People on the Bus

Say the important thing three times, since some slice of the room has always drifted off. Fence the idea in by showing what it isn't. Use verbal punctuation (numbered points, "now, the third thing") so anyone who fogged out can climb back on.

Ask the room a question, then wait. Seven seconds gets suggested as the most dead air a speaker can hold. Mary Budd Rowe's wait-time studies found teachers usually wait about a second and a half, while three to five seconds already gets fuller answers.

Book late morning, keep the lights full up (slides are hard to see through closed eyelids), walk the room beforehand, and pick one that will be more than half full.

Boards and Props

For teaching, a board beats slides- chalk moves at about the speed people absorb ideas, plus the hands get somewhere to go. Props stick in memory long after the words do. Hedda Gabler keeps a stove on stage the whole play. Once Løvborg's manuscript is in Hedda's hands, nobody in the seats doubts where it's headed.

Spin a bicycle wheel, push sideways on the rim, and ask which way it tips. Put duct tape on one spot and follow only that piece: it comes over the top, gets shoved sideways, keeps that motion on the way down... so does every piece after it. The whole wheel swings over, which physics calls precession.

Slides Are for Exposing, Not Teaching

  • Don't read them aloud. The audience can read.
  • Stand beside the screen, not across the stage from it.
  • Strip backgrounds, logos, titles and bullets, then cut words until the slide supports the speaker instead of competing.
  • Go big on type. One lecture hall settled on 40 to 50 point; the 10/20/30 rule puts the floor at 30.
  • Skip the laser pointer- aiming it turns the speaker's back to the room. Put a numbered arrow on the slide instead.
  • Print the deck and lay it on a table. A heavy one jumps out at a glance.

A talk gets one hapax legomenon- a linguistics term for a word that appears just once- meaning one deliberately impossible slide. The 2010 Afghanistan strategy diagram is the famous one; General McChrystal reportedly answered it with "When we understand that slide, we'll have won the war."

Job Talks- Vision in Five Minutes

Show vision (a problem people care about plus something new in the approach) and proof of done-something (the steps to get there, finished or not) inside five minutes. Close on contributions that mirror those steps. It's persuasion, the quick-fire kind in Why Lie? I Want Beer- Persuasion in a Split Second. Practise on friends who don't know the work- a supervisor fills the gaps from memory.

Five S's for Getting Remembered

Ideas are like kids- nobody wants to send them out into the world in rags.

5 S remembered Symbol a picture to hang it on Slogan a handle of a phrase Surprise what nobody expected Salient Idea the one that sticks out Story how, and why it matters

A 1970 MIT thesis that taught a program what an arch is fits all five: the arch as symbol, one-shot learning as slogan, learning from one example instead of a million as the surprise, the near miss (blocks beside the posts instead of across them) as the salient idea, plus the story of how it works.

How to Stop

The last slide stays up through the questions. Skip the collaborator wall (thank them on slide one), "Questions?", "The End" and "Conclusions"- title it Contributions and list what was done.

A joke works at the end, once everyone's tuned to the voice. "Thank you for listening" is the weak move- it hints everyone stayed out of politeness. Chris Christie's 2012 Republican keynote and Bill Clinton's 2012 Democratic nominating speech (Julián Castro gave that year's keynote) both closed on a benediction instead, "God bless you, and God bless America". Saluting the audience works too... what was great about being there, the wish to come back.

Worst slide crime you've sat through.. or the best closing line you've heard someone land? Leave it in the comments- would love to hear 'em!

Glossary

  • Empowerment promise — an opening line telling the audience what they will know by the end that they don't know now.
  • Verbal punctuation — spoken markers like numbered points that show where one part of a talk ends and the next begins.
  • Wait time — the pause between asking a question and speaking again or taking an answer.
  • Precession — the way a spinning object turns at right angles to a push instead of tipping the way it was pushed.
  • Hapax legomenon — a word that appears only once in a text; here, the single deliberately overwhelming slide a talk can get away with.
  • Job talk — the presentation a candidate gives to a hiring department, usually about their research.
  • One-shot learning — learning something definite from a single example instead of thousands.
  • Near miss — an example that is almost, but not quite, an instance of a concept; the small difference is what gets learned.
  • Benediction — a closing blessing, like "God bless you", used to signal the end of a speech or service.
