Who the correction actually serves

Most of us treat a correction like a small attack. Someone shows us we got it wrong and the body reacts before the mind does — heat in the face, the quick defense, the reason it wasn't really our fault. We protect the version of ourselves that was right, and in doing so we keep the mistake.

Marcus Aurelius, who could have had any flatterer in the empire, wanted the opposite: "If any man is able to convince me and show me that I do not think or act right, I will gladly change; for I seek the truth, by which no man was ever injured" (Meditations 6.21, Long). Read the last part slowly. No one is ever harmed by the truth. The person who corrects your bad weld, your wrong dosage, your miscounted till — they didn't injure you. They handed you something true and saved you the cost of staying wrong.

A stocker, a coder, a line cook: the skilled ones learn to feel that flush of defensiveness as a signal, not a verdict. The heat means something real just arrived. The question is whether you'll take it.

This is teachability at full strength — wanting the correction more than you want to have been right.
