Bringing to bear the expertise of three prize-winning economists and policy thinkers, “Noise: A Flaw in Human Judgment” represents one strand in a long examination of how humans flail at proper logical thinking. Even when bias is eliminated as much as possible, decision-making, according to these mavens, is subject to random noise that can shift outcomes unconscionably or incorrectly. Two individual judges, both “unbiased,” can tilt sentences drastically. Decisions made after lunch differ from those enacted before. Variability is rife. The authors write smoothly and convincingly, offering sparkling case studies, and their prescriptions for improvement should be read by all executives and officials. A brief book in basic content terms, Noise is worth brewing over.
