From the bestselling author of Thinking, Fast and Slow, the co-author of Nudge, and the author of You Are About to Make a Terrible Mistake! comes Noise, a revolutionary exploration of why people make bad judgments, and how to control both noise and cognitive bias.
Imagine that two doctors in the same city give different diagnoses to identical patients—or that two judges in the same courthouse give markedly different sentences to people who have committed the same crime. Suppose that different interviewers at the same firm make different decisions about indistinguishable job applicants—or that when a company is handling customer complaints, the resolution depends on who happens to answer the phone. Now imagine that the same doctor, the same judge, the same interviewer, or the same customer service agent 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, Olivier Sibony, and Cass R. Sunstein show the detrimental effects of noise in many fields, including medicine, law, economic forecasting, forensic science, bail, child protection, strategy, performance reviews, and personnel selection. Wherever there is judgment, there is noise. Yet, most of the time, individuals and organizations alike are unaware of it. They neglect noise. With a few simple remedies, people can reduce both noise and bias, and so make far better decisions.
Packed with original ideas, and offering the same kinds of research-based insights 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.

APPLE BOOKS REVIEW
Noise could be messing up your decision-making. Not the sound of incessant traffic or loud neighbors—the noise inside your head. Nobel-winning economist Daniel Kahneman (Thinking, Fast and Slow) investigates how everything from personal prejudices to time of day to even the weather can shape our choices and our lives in ways we aren’t aware of. Kahneman uses case studies from a variety of fields, ranging from insurance to medicine, to demonstrate with shocking specificity how distractions lead to errors across the board. Thankfully, he also offers simple but valuable suggestions for how to give ourselves a noise audit and see just how much our own decisions are impacted by distracting forces, both internal and external, we’ve never even noticed. Narrator Jonathan Todd Ross guides us through this fascinating journey with an easygoing style that makes it simple to understand. If you’re looking to cut the clamor and make choices with greater clarity, Noise will be music to your ears.
