The central thesis of this text is that noise, defined as variability in judgments that should be identical, has detrimental effects across many fields [1, 2]. Individuals and organizations are often unaware of this noise and neglect it, despite its pervasive presence wherever judgment is made [1].
The book explains how and why humans are susceptible to noise in judgment and proposes simple remedies to reduce both noise and bias, leading to better decisions [1]. The authors, Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein, illustrate the concept of noise with examples such as differing diagnoses for identical patients by doctors, varied sentences by judges for similar crimes, and inconsistent hiring decisions by interviewers [2].

From the book
man, 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…
Title: Noise by Daniel Kahneman, Olivier Sibony, Cass R. Sunstein Description: NEW YORK TIMES BESTSELLER From the Nobel Prize-winning author of Thinking, Fast and Slow and the coauthor of Nudge, a revolutionary exploration of why people make bad judgments and how to make better ones—"a tour de force” (New York Times). 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…
