“Mindful awareness of how dissonance operates is therefore the first step toward controlling its effects. But two psychological impediments remain. One is the belief that mistakes are evidence of incompetence and stupidity; the other is the belief that our personality traits, including self-esteem, are embedded and unchangeable. People who hold both of these ideas are often afraid to admit error because they take it as evidence that they are blithering idiots; they cannot separate the mistake from their identity and self-esteem. Although most Americans know they are supposed to say “We learn from our mistakes,” deep down they don’t believe it for a minute. They think that making mistakes means they are stupid. That belief is precisely what keeps them from learning from their mistakes.”
