The marvels and the flaws that I’ll be talking about are the marvels and the flaws of intuitive thinking. It’s a topic I’ve been thinking about for a long time, a little over 40 years. I wanted to show you a picture of my collaborator in this early work. What I’ll be trying to do today is to sort of bring this up-to-date. I’ll tell you a bit about the beginnings, and I’ll tell you a bit about how I think about it today.
