Why do people sometimes become more committed to a belief when the evidence begins to contradict it?

Welcome to Crisis in Perception, where we examine the systems shaping our world.
In The Folly of Fools: The Logic of Deceit and Self-Deception in Human Life, evolutionary biologist Robert Trivers challenges conventional explanations of why humans deceive themselves. Rather than viewing self-deception primarily as a way to protect emotional well-being, Trivers proposes that it evolved to make deception of others more successful.
This Deep Dive investigates the mechanisms behind that hypothesis: unconscious information processing, selective memory, cognitive dissonance, rationalization, and the evolutionary competition between deception and detection.
Drawing on psychological experiments and Trivers' examination of Air Florida Flight 90, the episode explores how apparently sincere confidence can coexist with distorted perceptions of reality. It also considers how these tendencies may scale beyond individuals, affecting institutional decisions, the treatment of contradictory evidence, and the ability to recognize dangerous mistakes.
The investigation distinguishes Trivers' evolutionary interpretation from established findings and examines how scientific methods and external feedback can help counteract our susceptibility to self-deception.
At its center is a question with consequences far beyond individual dishonesty: what happens when the people most confident in their understanding are also the least willing to question it?
