Al Gore’s TED talk is chock-full of evidence to make his point. I’m using the word evidence here loosely to include all the techniques he uses. There’s stories, examples, analogies, quotes, metaphors, and statistics.
I did an analysis of how much of the body of his talk was composed of evidence. Here are the results:
So that’s about 60% of his talk. It’s the evidence which makes a presentation engaging and interesting to listen to. It’s the evidence which makes a presentation credible and persuasive. How much do you use in your talks? How would your presentations stack up against Al Gore’s?
