A live verbal presentation is one of the worst ways to transmit information, because a talk given in real time exists to deliver emotion.

If you want to exchange or deliver information to a group of people, one of the worst ways to do it is with a live verbal presentation. If your goal is actually to deliver that scientific paper or that insight, then you should either write a book or write a memo and say, here, in an asynchronous way, this is what we know. If you're going to show up live, in person, in real time, synchronized, you are performing. And the goal is to not deliver the information, but to deliver emotion.
