“I’ve been tweeting about irrationality since 2017, and in that time I’ve noticed a disturbing pattern. Whenever I post of a cognitive bias or logical fallacy, my replies are soon invaded by leftists claiming it explains rightist beliefs, and by rightists claiming it explains leftist beliefs. In no cases will someone claim it explains their own beliefs. I’m likely guilty of this too; it feels effortless to diagnose others with biases and fallacies, but excruciatingly hard to diagnose oneself. As the famed decision theorist Daniel Kahneman quipped, ‘I’ve studied cognitive biases my whole life and I’m no better at avoiding them.’”
