"Why admit and apologize for errors? Two reasons: First, blame is a seesaw. If you blame yourself more, others blame you less; they may even tell you why it wasn’t really your fault, everybody else got it wrong too, you were misled, etc. And second, the forgiveness process starts with acknowledgment. It is vanishingly hard to forgive people who won’t admit fault."
