How does common knowledge become… common knowledge? Steven Pinker is a cognitive psychologist and professor at Harvard University. He joins Preet to discuss his latest book, When Everyone Knows That Everyone Knows...: Common Knowledge and the Mysteries of Money, Power, and Everyday Life, about how shared awareness shapes norms and shifts collective behavior.

Then, Preet answers your questions about America’s very first law enforcement agency and Border Czar Tom Homan’s alleged $50,000 bribe.

In the bonus for Insiders, Preet and Pinker discuss how laughter and comedy informs common knowledge and vice versa.
