Synthesized answer
Noise refers to variability in judgments that should be identical [1]. The book "Noise" by Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein explores this concept, providing examples such as two doctors giving different diagnoses to identical patients, or two judges imposing different sentences for the same crime [1]. This variability can also occur with the same individual, where decisions differ based on the time of day or day of the week [1].
The detrimental effects of noise are present in many fields, including medicine, law, and personnel selection [2]. The authors highlight that individuals and organizations are often unaware of noise and tend to neglect it [2]. However, the book suggests that with simple remedies, it is possible to reduce both noise and bias to make better decisions [2]. The passages explain what noise is and where it can be found, but they do not provide a detailed explanation of the authors' key concepts in their own words beyond this definition and description of its impact.

From the book
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…
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…
