Thinking, Fast and Slow — Daniel Kahneman (Review)
Kahneman’s Thinking, Fast and Slow explains how two systems of thinking shape our decisions — and why our minds often misjudge risk, probability, and patterns.
Summary
Daniel Kahneman’s Thinking, Fast and Slow is a landmark book in psychology and behavioral economics. Drawing on decades of research conducted with Amos Tversky, Kahneman explains how two systems of thinking — fast, intuitive “System 1” and slow, analytical “System 2” — shape judgment and decision-making. Through memorable experiments and clear explanations, the book reveals how cognitive biases influence everything from everyday choices to business strategy and public policy.
