How Common Knowledge Rules the World

Today’s big ideas come to us from Harvard cognitive psychologist, public intellectual, and bestselling author Steven Pinker, who’s out with a new book called When Everyone Knows That Everyone Knows… Common Knowledge and the Mysteries of Money, Power, and Everyday Life​. In it, he shows how public, shared awareness shapes everything from markets and politics to first dates and social media pile‑ons, and why understanding it can make you a sharper decision‑maker and a better collaborator. 📱 Follow The Next Big Idea Daily on Apple Podcasts, Spotify, or wherever you listen 📩 Want more bite-sized insights from the best new nonfiction delivered straight to your inbox?
