Book Reviews

  • I think Noise will make a bigger impact than Thinking Fast and Slow. It is an amazing and deep book exploring an overlooked and under appreciated source of error. Don’t miss this one! https://t.co/9D85WKcZgeLink to Tweet
  • "Wherever there is judgment, there is noise. Yet, most of the time, individuals and organizations alike are unaware of it. They neglect noise." Robert Cialdini, Annie Duke, Philip Tetlock and Angela Duckworth give glowing back cover blurbs. https://t.co/eKL6l2po5KLink to Tweet
  • This book will have a deep and positive impact on your decision-making. Cognitive bias is all the rage. But noise may be the bigger flaw in human judgment. https://t.co/JyIPfPIwHvLink to Tweet

About Book

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.
