The Dunning-Kruger Effect - Cognitive Bias - Why Incompetent People Think They Are Competent | After Skool
Summary
This episode explores the Dunning-Kruger effect, a cognitive bias where people with low ability overestimate their competence while experts underestimate theirs. Using the story of MacArthur Wheeler’s lemon juice bank robbery, the host explains how this bias distorts self-perception across various fields, from driving to medicine. The discussion highlights that while confidence is valuable, accurate self-assessment is crucial for growth, and the internet often amplifies overconfident novices.
