Bryan Caplan on the Rationally Speaking Podcast: Julia gave Bryan one of the best interviews I've heard. She was very challenging, and really tried to break his theory. Bryan replied brilliantly.
Steven Pinker on the Ezra Klein Show: Ezra Klein is so much better in speaking than writing. It's not like his writing is bad, it's just so slanted toward liberalism. When he speaks he's much more thoughtful. His approach is much more detached, and every bit as articulate.
Steven Pinker of course is delightful. He's one of my favorite intellectuals to listen to. The vocabulary he uses to capture ideas is one of his greatest advantages.
Jordan Peterson joined Russ Roberts on Econtalk: They get into Jordan's book 12 rules for life, and talk about the bible a little more than I would expect.
