Analysis of a speech by Dan Gilbert

Dan Gilbert is a Harvard psychologist who has spent a lot of time thinking about and studying happiness. He is the author of Stumbling on Happiness. The New York Times Book Review wrote, “Gilbert’s elbow-in-the-ribs social-science humor is actually funny. … But underneath the goofball brilliance, [he] has a serious argument to make about why human beings are forever wrongly predicting what will make them happy.”

In his 2004 TED Talk, Gilbert shares fascinating insights into the surprising science of happiness. Below, I have selected some of the things that I liked as well as suggestions for improvement.

What I liked


Dan Gilbert has great enthusiasm for his subject. You hear it in his voice; you see it in the way he moves and gestures. That enthusiasm draws you in and keeps you interested in the subject. As John Wesley said, “Catch fire with enthusiasm and people will come from miles around to watch you burn.”


Gilbert shows that humour has its place even in a scientific or technical presentation. It lightens the mood, keeps the energy high and improves the attention and engagement of the audience.

A few examples:

  • “When you have 21 minutes to speak, two million years seems like a really long time. But evolutionarily, two million years is nothing.” (0:11)
  •  “You’re watching happiness be synthesized. Would you like to see it again? Happiness! ‘The one I got is really better than I thought! That other one I didn’t get sucks!’ That’s the synthesis of happiness.” (10:50)
  • “The psychological immune system works best when we are totally stuck, when we are trapped. This is the difference between dating and marriage. You go out on a date with a guy, and he picks his nose; you don’t go out on another date. You’re married to a guy and he picks his nose? He has a heart of gold. Don’t touch the fruitcake! You find a way to be happy with what’s happened.” (14:56)

Importantly, the humour is directly related to the topic at hand. And, Gilbert doesn’t tell jokes; rather, he looks for the underlying humour that exists in most any situation.

Rhetorical devices

metaphor is a rhetorical device that compares two things (that are often not alike) by stating that one is the other. At 1:06 Gilbert uses a flight simulator as an excellent metaphor to explain the pre-frontal cortex (our “experience simulator”).

Metaphors are simple but powerful ways to explain something new to your audience. You link your idea to something with which the audience is already familiar and the new idea becomes easier to understand.

Anaphora is the repetition of a word or phrase at the beginning of successive sentences or clauses. Repetition adds rhythm and emotion to the words and makes them memorable.

At 20:30, Gilbert uses a couple of anaphoras that build nicely to his conclusion:

When our ambition is bounded, it leads us to work joyfully. When our ambition is unbounded, it leads us to lie, to cheat, to steal, to hurt others, to sacrifice things of real value. When our fears are bounded, we’re prudent, we’re cautious, we’re thoughtful. When our fears are unbounded and overblown, we’re reckless, and we’re cowardly.


Dan Gilbert uses concrete examples to explain his points. I particularly appreciated the detailed way in which he described the experiment with the Monet paintings (9:34), the experiment with the photography course (15:30) and the stories of the three men from the newspapers (Jim Wright, Moreese Bickham and Harry Langerman).

Being concrete by, among other things, using specific examples, is a good way to make your speech memorable.


At 9:15, Gilbert makes a reference to the talk by Buddhist Monk Matthieu Ricard who also spoke at the same event. It is a very subtle thing, but it shows good presence of mind on the part of Gilbert.

If you speak at an event and can reference a previous speaker, it’s a nice callback for the audience and shows that you are paying attention to others, and that you can think quickly enough to incorporate something into your talk that someone else has just said.



For me, Gilbert paces back and forth too much. Perhaps it is his enthusiasm, or an attempt to connect with the different parts of the audience, or both. Regardless, I found it distracting at times. Movement is important and I wouldn’t want Gilbert to stand in one place for the whole talk; however, it would be nice to see him stand in one spot from time to time when making an important point. When you move on stage, move with purpose.

Speaking rate

As stated above, I love the enthusiasm with which Dan Gilbert speaks. But on several occasions, I thought that he could have slowed down a bit and paused to let us keep up with him. In fact, at one point, he is going so quickly that he misspeaks on an important point.

After nicely explaining a test that was done with a group of Harvard University students who were asked to choose one of two different photographs, Gilbert comes to the key finding on the issue of happiness. He states:

They don’t like their picture, and in fact even after the opportunity to swap has expired, they still don’t like their picture. Why? Because the irreversible condition is not conducive to the synthesis of happiness. [Emphasis added.]

Now, this statement will not make sense unless you watch the video. But when I heard it, I was confused. Everything that had been said before led me to believe the opposite. I puzzled about this for a moment and then I remembered that TED conveniently provides a transcript for many of its talks. So I checked. And this is what I found:

They don’t like their picture, and in fact even after the opportunity to swap has expired, they still don’t like their picture. Why? Because the [reversible] condition is not conducive to the synthesis of happiness. [Emphasis added.]

So I hadn’t missed anything. It was just that Gilbert misspoke. The TED transcript inserts the correct word in brackets. Now, of course, mistakes happen and nobody is perfect. But it is a good reminder of the importance of not speaking too quickly and of pausing at key moments.


Gilbert had some good slides, but he didn’t always display them as effectively as he could have.

On a couple of occasions, Dan Gilbert put up a slide too early; in other words, he put up a slide but continued to finish the previous thought. At other times, he left a slide up after he had moved on to the next point. Neither is ideal because it increases the chance of a disconnect between speaker and audience. You’re speaking about one thing and the audience is reading slides that say something else.

When showing slides, you want to click into a slide just as you begin to speak about it. When you have finished, don’t let the slide linger too long. If don’t have another slide to show for a while, then fade to black, either with your remote or by inserting a black slide in the deck.

Another way in which Gilbert could improve his slides would be to use animation to bring in points one by one. Many of the slides were dense.

Putting the entire slide up at once is a surefire way to get the audience reading. And the audience can read faster than you can speak, which means that they are going to get ahead of you. Using animations to bring in points one at a time ensures that you keep your audience with you.

The clearest example of this occurs around 7:50. Here Dan Gilbert reveals the “secret of happiness”. It is an extremely clever and funny twist that delights the audience. However, the four jokes are all displayed at once. So, when Gilbert gets to the final (and best) joke about never joining the Beatles, we have all read it. The impact is diluted.

  1. Thanks for the detailed analysis, John. I’d not seen this talk, and I found it fascinating.

    A couple of things struck me about this talk. For me, the most striking was that he paces throughout, as you say. It fits with his style I suppose, but as you mentioned, it would’ve been good to see him “stand and deliver” when he came to a key point.

    The other main thing that struck me was that the whole talk felt like it was rather rushed, as you did. He started by talking about how little time he had, saying “When you have 21 minutes to speak…”. (So in that case, sadly the word “you” was about himself.) And I felt he ended in a similarly rushed way, because to me his conclusion seemed to be just his last sentence.

    All the same, I enjoyed the talk and your analysis of it, so I appreciate you sharing it.

    1. Good points, Craig. The speech did feel rushed. I can imagine Gilbert cutting and cutting material until he reached a point where he could not stand to cut any more. I do think he could have shortened some of the stories. Having said that, his enthusiasm for the subject (and the subject itself) kept me interested to the end.

John delivered a keynote address about the importance of public speaking to 80 senior members of Gore’s Medical Device Europe team at an important sales event. He was informative, engaging and inspirational. Everyone was motivated to improve their public speaking skills. Following his keynote, John has led public speaking workshops for Gore in Barcelona and Munich. He is an outstanding speaker who thinks carefully about the needs of his audience well before he steps on stage.

I first got in touch with John while preparing to speak at TED Global about my work on ProtonMail. John helped me to sharpen the presentation and get on point faster, making the talk more focused and impactful. My speech was very well received, has since reached almost 1.8 million people and was successful in explaining a complex subject (email encryption) to a general audience.

John gave the opening keynote on the second day of our unit’s recent offsite in Geneva, addressing an audience of 100+ attendees with a wealth of tips and techniques to deliver powerful, memorable presentations. I applied some of these techniques the very next week in an internal presentation, and I’ve been asked to give that presentation again to senior management, which has NEVER happened before. John is one of the greatest speakers I know and I can recommend his services without reservation.

After a morning of team building activities using improvisation as the conduit, John came on stage to close the staff event which was organised in Chamonix, France. His energy and presence were immediately felt by all the members of staff. The work put into the preparation of his speech was evident and by sharing some his own stories, he was able to conduct a closing inspirational speech which was relevant, powerful and impactful for all at IRU. The whole team left feeling engaged and motivated to tackle the 2019 objectives ahead. Thank you, John.

I was expecting a few speaking tips and tricks and a few fun exercises, but you went above and beyond – and sideways. You taught me to stand tall. You taught me to anchor myself. You taught me to breathe. You taught me to open up. You taught me to look people in the eye. You taught me to tell the truth. You taught me to walk a mile in someone else’s shoes. I got more than I bargained for in the best possible way.

John gave a brilliant presentation on public speaking during the UN EMERGE programme in Geneva (a two days workshop on leadership development for a group of female staff members working in the UN organizations in Geneva). His talk was inspirational and practical, thanks to the many techniques and tips he shared with the audience. His teaching can dramatically change our public speaking performance and enable us as presenters to have a real and powerful impact. Thank you, John, for your great contribution!

John is a genuine communication innovator. His seminars on gamification of public speaking learning and his interactive Rhetoric game at our conference set the tone for change and improvement in our organisation. The quality of his input, the impact he made with his audience and his effortlessly engaging style made it easy to get on board with his core messages and won over some delegates who were extremely skeptical as to the efficacy of games for learning. I simply cannot recommend him highly enough.

John joined our Global Sales Meeting in Segovia, Spain and we all participated in his "Improv(e) your Work!" session. I say “all” because it really was all interactive, participatory, learning and enjoyable. The session surprised everybody and was a fresh-air activity that brought a lot of self-reflection and insights to improve trust and confidence in each other inside our team. It´s all about communication and a good manner of speaking!"

Thank you very much for the excellent presentation skills session. The feedback I received was very positive. Everyone enjoyed the good mix of listening to your speech, co-developing a concrete take-away and the personal learning experience. We all feel more devoted to the task ahead, more able to succeed and an elevated team spirit. Delivering this in a short time, both in session and in preparation, is outstanding!

Be BOLD. Those two words got stuck in my head and in the heads of all those ADP leaders and associates that had the privilege to see John on stage. He was our keynote speaker at our annual convention in Barcelona, and his message still remains! John puts his heart in every word. Few speakers are so credible, humble and yet super strong with large audiences!
