description: 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. 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. 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. 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. These are examples of noise: variability in judgments that should be identical. In Noise Daniel Kahneman Cass R. 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. 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. Drawing 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.
