167. The Secret of Humanity? It’s Common Knowledge.

Steven Pinker’s new book argues that all our relationships depend on shared assumptions and “recursive mentalizing” — our constant efforts to understand what other people are thinking. He and Steve talk about the psychology of eye contact, the particular value of Super Bowl ads, and what it’s like to get cancelled.
