Finally Found The Word For It
Anosognosia is a condition in which a person who suffers from a disability seems unaware of or denies the existence of his or her disability.
Great piece by Errol Morris in the NYT, explaining why people blithely continue making the same mistakes, even in light of being shown the error of their ways. Insert a personal example about yourself, a friend, a co-worker or boss into the definition and it becomes even clearer.
A must read.
