People - lots of people, including me, enough of the time... people take correction as criticism and they don't hear criticism. But the real dysfunction is what comes after. Which is to say that the corrected/criticized person either is too tangled in his wiring to ever regroup and rethink, or, even if he's not, he simply doesn't, and he has no friend or ally - someone whom he perceives is on his side but sees the truth of the correction - to help him think and regroup. So where the dysfunction is most destructive isn't in the individual but in the larger conversations.
