The way someone handles being corrected matters beyond whether they were right the first time.

Everyone is wrong sometimes, and that tells you little. What it costs a person to accept a correction tells you a great deal, because it predicts what happens the next hundred times information arrives that they did not want. Defensiveness is expensive to be near, and it slows down every fact that has to travel toward them.

Watch your own first ten seconds after somebody corrects you this week. You are not aiming for gratitude on cue, only for a pause in front of the reflex.
