Steven Pinker is Johnstone Family Professor of Psychology at Harvard University. He is an experimental cognitive psychologist who writes on language, mind, and human nature. In this episode—the hundredth of Robinson’s Podcast (!)—Robinson and Steve talk about his recent book Rationality: What It Is, Why It Seems Scarce, Why It Matters (Penguin, 2022), which is linked below. More particularly, they discuss rationality’s evolutionary basis, how it is subverted by conspiratorial thinking and other dimensions of the “mythology mindset”, how it relates to enlightenment and human progress, and the state of free speech at Harvard and in the academic world at large.
