How Intuition Drives Error

Thinking, Fast and Slow presents Daniel Kahneman’s framework for understanding how people think, judge, and make decisions. The book organizes cognition into two modes: fast, intuitive mental processes and slower, effortful reasoning.

Kahneman connects these systems to common errors in judgment, including bias, overconfidence, and flawed risk perception. Concepts such as anchoring, availability, loss aversion, and framing show how easily intuition misleads, even among trained professionals.

The writing translates behavioral science into accessible explanations, supported by experiments and real-world examples. Its central value lies in giving readers a vocabulary for recognizing predictable mental patterns that shape choices in finance, medicine, policy, and daily life.

Influence Beyond Psychology

The book became one of the most influential works of popular psychology and behavioral economics of the 21st century. It reached bestseller status and helped bring core ideas from cognitive science into mainstream conversation.

Terminology entered professional environments, influencing product design, business strategy, and policy thinking. It strengthened Kahneman’s public profile and extended decades of research into a widely adopted framework for decision-making analysis.

Thinking, Fast and Slow also fueled broader interest in behavioral science, shaping how organizations evaluate risk, incentives, and human error. Its impact endures through ongoing reference in education, consulting, and public debate around rationality and judgment.
