Noise: A Flaw in Human Judgment by Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein examines the hidden variability that affects human judgment and explains why different people—or even the same person at different times—can reach inconsistent conclusions when faced with similar situations. The book explores how noise influences decisions in medicine, law, business, forecasting, hiring, performance evaluation, and many other fields, while distinguishing it from systematic bias. It introduces practical ideas such as decision hygiene, structured judgment, independent assessments, and methods for reducing unwanted variability in organizations. Written for readers interested in psychology, decision-making, management, and behavioral science, the book combines research with real-world examples to show how better processes can lead to more consistent and reliable judgments.
