Sorry if I wasn't clear. I want to be good at admitting that I was in error, and to collect cases of great thinkers who failed to do that. So yes, I want to be less wrong. Admitting one's errors is a tool in the less wrong toolbox. We like to think we're good at it, that its easy, that we're detached, but I've seen that being content with my level of self-criticality creates complacency and fosters lapses. These examples demonstrate it.
