The book explores the two systems driving our thinking: System 1 (fast, intuitive, automatic) and System 2 (slow, deliberate, logical). Kahneman shows how our mind’s shortcuts, biases and heuristics lead to errors in judgment and decision-making—even when we believe we are being rational. He presents insights from decades of research in psychology and behavioral economics, and offers ways to think more clearly, make better decisions, and understand why we act the way we do.
