Noise, A Flaw in Human Judgment

This work investigates the pervasive problem of noise in human decision-making, where identical cases produce wildly different outcomes depending on who is judging. Drawing from extensive research in psychology and behavioral economics, it demonstrates how random variability undermines fairness and accuracy across professions from medicine to criminal justice. The analysis combines rigorous scientific methodology with accessible explanations, targeting professionals, policymakers, and general readers interested in improving judgment systems. It offers both sobering insights into human fallibility and practical strategies for reducing harmful inconsistency in critical decisions.
