Noise: A Flaw in Human Judgment

byDaniel Kahneman,Olivier SibonyandCass Sunstein

Daniel Kahneman, Olivier Sibony, and Cass Sunstein examine “noise,” the unwanted variability that causes equally qualified people to make different judgments from the same facts. In courts, medicine, hiring, insurance, forecasting, and performance evaluation, decisions can depend on which professional handles a case or even that person's mood and timing. The authors distinguish noise from systematic bias and show why organizations often overlook it. They propose decision hygiene—structured comparisons, independent assessments, explicit criteria, and statistical thinking—to reduce inconsistency while preserving necessary judgment. The book reveals fairness as a problem of variability as well as prejudice.
