Dysfunctionally conscientious people feel shame so acutely that it leads to maladaptive outcomes.

They normally are so self-censoring that they never even produce a thing they don't think is perfect.

When someone gives them negative feedback about a thing they didn't realize was bad it feels like an existential threat.

So they sometimes lash out at the person who said it and try to punish them for it and get them to apologize.

This is something I've discovered about myself in over a decade of couples counseling.
