Munger presents the ability to recognise one’s own mistakes as a valuable intellectual skill. People naturally become attached to their opinions and previous decisions, which can make it difficult to accept evidence that contradicts them. Acknowledging an error allows a person to correct course rather than defend a position that no longer fits the facts.

The quote therefore links good judgement with intellectual humility. Being wrong is unavoidable, but remaining wrong for longer than necessary can create larger problems. The capacity to revise a belief, strategy or decision can limit damage and improve future choices.

More broadly, Munger treats error recognition as a practical advantage. It supports learning because mistakes become sources of information rather than threats to identity or status. In business, investing and everyday life, the willingness to admit error can help people adapt more quickly and make better-informed decisions.
