And although noise can be found wherever people make judgments and decisions, individuals and organizations alike are commonly oblivious to the role of chance in their judgments and in their actions.ĭrawing on the latest findings in psychology and behavioral economics, and the same kind of diligent, insightful research that made Thinking, Fast and Slow and Nudge groundbreaking New York Times bestsellers, Noise explains how and why humans are so susceptible to noise in judgment - and what we can do about it. Sunstein, and Olivier Sibony show how noise contributes significantly to errors in all fields, including medicine, law, economic forecasting, police behavior, food safety, bail, security checks at airports, strategy, and personnel selection. These are examples of noise: variability in judgments that should be identical.

Now imagine that the same doctor, the same judge, the same inspector, or the same company official makes different decisions, depending on whether it is morning or afternoon, or Monday rather than Wednesday. Suppose that different food inspectors give different ratings to indistinguishable restaurants - or that when a company is handling customer complaints, the resolution depends on who happens to be handling the particular complaint. Imagine that two doctors in the same city give different diagnoses to identical patients - or that two judges in the same courthouse give different sentences to people who have committed the same crime. From the bestselling author of Thinking, Fast and Slow and the co-author of Nudge, a groundbreaking exploration of why most people make bad judgments, and how to control for that noise.
