Self-deception is structural: brains destroy the information they acquire
Robert Trivers argued that the human brain was designed to deceive itself. We distort information to make ourselves appear better than we actually are. A contradiction lies at the heart of human intelligence: our brains simultaneously seek out information and destroy it after acquisition. Our minds evolved to make sense of the world in ways that help us survive — not in ways that are true. The more we distort information, the more rational we think we are. We applaud ourselves for clear thinking even as we see the world through a tainted prism of self-serving beliefs.
"We deceive ourselves the better to deceive others."
Combined with Henrich's conformist transmission, self-deception is structural, not a character flaw. Given this baseline, strong opinions are something you have to earn — through rigorous writing and sustained dialogue, not credentials accumulated like a Black Friday shopper, and not in 24 hours. The less time you give yourself to think, the more you'll settle on socially rewarded points of view, because self-deception and social conformity both push in the same direction.
Trivers showed that a little self-deception maintains social cohesion, which means the mechanism isn't simply broken — it's doing exactly what it was selected to do. That's what makes it so hard to override.
Source claim: Trivers showed that self-deception is a structural feature of human cognition — we distort information to survive, not to find truth — which means independent reasoning requires deliberate, slow effort against our own biology.
