Scott Alexander criticizes the tendency to focus on easily debunked fringe beliefs like moon-hoaxing and homeopathy when discussing rationality. He argues that this approach is counterproductive, as it trains people to dismiss opposing views too quickly and lose the ability to doubt their own beliefs. The post suggests that constantly debunking obvious falsehoods can 'inoculate' people against questioning more complex issues, potentially hampering their ability to engage in genuine critical thinking and self-doubt. Scott emphasizes that true rationality involves recognizing one's own potential for error, even in strongly held beliefs. Shorter summary
