Freddie Sayers sits down with renowned cognitive psychologist, author, and Harvard Professor of Psychology Steven Pinker to discuss his latest book, When Everyone Knows That Everyone Knows... and explore how common knowledge shapes our social, political, and economic worlds.

Their conversation delves into the power and pitfalls of collective thinking, the dynamics of cancel culture and censorship, and the Trump administration’s clashes with academic institutions like Harvard. They also consider whether democracy is in decline, if society is losing its shared sense of reality, and whether there’s still reason to be optimistic about the future.
