I think the OP has a flaw in his original premise - that pilots have an overriding interest in correcting their own mistakes. I think we have a greater-than-normal interest in correcting OTHERS' mistakes. We pore over accident reports and speculate as to what the incident pilot did wrong, say "There but for the grace of god", etc. But, when faced with direct criticism of our own actions, such as someone approaching you on the ramp after a flight, I think we take the feedback no better or worse than any other population - all based on the personalities involved in the conversation.
