Noise: A Flaw in Human Judgment – Daniel Kahneman, Olivier Sibony, Cass R. Sunstein
The Sunday Times bestseller (May 2021)
‘A tour de force of scholarship and clear writing’
New York Times
‘As you’d expect from its authors, it is a rigorous approach to an important topic… There’s lots to surprise and entertain. Anyone who has found the literature on cognitive biases important will find this a valuable addition to their knowledge’ Danny Finkelstein, The Times
‘The greatest source of ineffective policies are often not biases, corruption or ill-will, but three “I”: Intuition, Ignorance and Inertia. This book masterfully demonstrates why the three “I” are so pervasive, and what we can do to fight them. An essential, eye opening read’
Esther Duflo, winner of a 2019 Nobel Prize

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.
