A Landmark Exploration of the Mind

Nobel laureate Daniel Kahneman summarizes decades of research on how people actually think — not how economists assume they think. His framework of two systems (fast, intuitive System 1 and slow, deliberate System 2) reveals the systematic errors in human judgment that affect everything from business decisions to personal happiness.

Kahneman and his late collaborator Amos Tversky revolutionized economics by proving that humans are not the rational actors classical theory assumed. Thinking, Fast and Slow made this research accessible to a general audience, revealing the cognitive biases that shape every decision we make — often without our awareness.
