About this episode
There are few (if any!) people alive whose work I think more highly of than Steven Pinker, or whose books have done more to shape my worldview. As he was in Los Angeles as part of his latest book tour, I took the opportunity to invite him on the show for an in-person interview. I did a podcast with him on Rationality, his last book, and wrote the following at the time: “One of the best parts of becoming (sort of) famous in the last year has been getting to meet and form relationships with some of my intellectual heroes. Seeing those I’ve looked up to for years not only become friends but in many cases return the admiration has been extremely rewarding.”That remains true, and although we’ve corresponded over the years, this discussion was the first time we met in person. The topic was his new book When Everyone Knows That Everyone Knows...: Common Knowledge and the Mysteries of Money, Power, and Everyday Life.We begin by discussing the Aumann Agreement Theorem, which I thought sounded trite from the book but came around to believing was endlessly fascinating after hearing Steve explain it. We spend a bit of time on humor, which is such an important part of social relations but rarely given the scholarly attention it deserves, or else we might say the theories that do exist are usually unsatisfying. I liked our discussion of how presidents and leaders engage in self-deprecating humor, and different public figures that either poke fun at themselves or the other side. I feel like the topic of politics and humor could make a fascinating PhD dissertation. If I had time, I would listen to podcasts and classify when people laughed and according to what criteria, and try to theorize about differences between groups like conservatives and liberals, or centrists and extremists. I think AI could probably help with that at this point. As I told Steve, perhaps we should all decide to support political movements that engage in more self-deprecating humor on the grounds that they are less likely to violate the rights of others! If you’re a graduate student or professor who is interested in doing such work, please reach out, as I would like to help find ways to make it happen. Moving on from the new book, I got to ask Steve something I’ve been wondering about for a few years, which is whether recent events, particularly the war in Ukraine, have shifted his views on what maintains peace in the international system. As it turns out, we were both surprised that under contemporary conditions you could see two European countries kill each other in such large numbers. Maybe the great run of peace we’ve had since 1945 isn’t a result
