In this episode of Books Deep Dive, we explore Noise: A Flaw in Human Judgment by Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein. Noise is the unnoticed variation in human judgment that leads to inconsistencies in hiring, legal rulings, medical diagnoses, and even college admissions. We discuss how factors like weather, hunger, and mood can shape decisions in unexpected ways, why algorithms often outperform humans, and how we can minimize noise to improve fairness and accuracy. Whether you're a leader, policymaker, or just someone who wants to make better choices, this episode will change how you see decision-making.
