Alejandro Moreno Posted over 1 year ago Shawn Achor: The happy secret to better work No matter how great the speech, if you don't know how to carry out its delivery, it will be a wasted effort. A key tenet for any public speaker is the ability to connect with an audience. Part of that connection is based on the speech's delivery. Humor allows people to connect with you. The more they connect with you, the more they will retain about what you said. Humor also creates positive energy, and as Shawn Anchor said, positive energy increases intelligence, creativity and energy levels, and can lead to dopamine production which turns on your learning centers. All these will make for a more receptive audience as well. Since you yourself said "this is a great speech and has many great and valid points", then you will probably not disagree with Shawn Anchor's points about positive energy, and therefore the usefulness of humor in a public speech. More importantly however, just because you don't appreciate humor in a public speech, does not mean it "takes away from the great points of his speech" for other people. We're all different, and we each have our own lens through which we view the world. I'm not saying you're wrong, I'm just saying we're all different.
