"According to psychologist, speaker and author Guy Winch, most people who consistently refuse to admit they're wrong do so because
they have incredibly fragile egos. They clam up and insist they're right, demonstrating what experts term "psychological rigidity", as a defense mechanism. Their subconscious feeling is that, if they dig in their heels, they can protect themselves from the consequences that might come from their imperfection and fallibility (e.g., being seen as weak, loss or retaliation). Winch also notes that some people go to extraordinary lengths in this process, even changing facts and convincing themselves of new realities in their own minds to escape culpability."
