The Hidden Force Controlling Money, Power and Your Choices

Jim Kwik, Steven Pinker

Jim Kwik talks with Harvard psychologist Steven Pinker about common knowledge — the idea that much of human behavior depends not just on what we know, but on what we know everyone else knows. They explore how this invisible layer shapes money, authority, social norms, cancel culture, and the spread of misinformation. Pinker offers tools from his books Rationality and When Everyone Knows That Everyone Knows to think more clearly, resist cognitive biases, and navigate a hyper-connected world.
