Thinking Fast and Slow

Thinking, Fast and Slow is the definitive account of the dual-process theory of mind developed by Nobel laureate Daniel Kahneman. He describes two modes of thought: System 1, which is fast, intuitive, emotional, and often wrong; and System 2, which is slow, deliberate, and logical but lazy. Through decades of research conducted with his late partner Amos Tversky, Kahneman shows how cognitive biases, anchoring, availability, the planning fallacy, loss aversion, and dozens more, systematically distort our judgements in predictable ways. The book spans psychology, economics, statistics, and decision theory, offering both an intellectual history of behavioural economics and a practical guide to making better decisions in business, medicine, investing, and everyday life.
