Mistakes were made (but not by me): why we justify foolish beliefs, bad decisions and hurtful acts (3rd edition.)

Why is it so hard to say "I made a mistake"-and really believe it?

When we make mistakes, cling to outdated attitudes, or mistreat other people, we must calm the cognitive dissonance that jars our feelings of self-worth. And so, unconsciously, we create fictions that absolve us of responsibility, restoring our belief that we are smart, moral, and right-a belief that often keeps us on a course that is dumb, immoral, and wrong. Backed by years of research, Mistakes Were Made (But Not by Me) offers a fascinating explanation of self-justification-how it works, the damage it can cause, and how we can overcome it. This updated edition features new examples and concludes with an extended discussion of how we can live with dissonance, learn from it, and perhaps, eventually, forgive ourselves.
