Noise: A Flaw in Human Judgment by Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein explores the hidden biases and inconsistencies—known as "noise"—that affect our decisions. From judicial rulings to medical diagnoses and corporate strategies, the book reveals how seemingly identical cases can lead to drastically different outcomes due to unpredictable variability in judgment. Backed by research and real-world examples, it offers practical strategies to reduce noise and improve decision-making accuracy across professions.
