The object of the superior man is truth.

Aiming at what is so means being willing to lose an argument to it. Plenty of capable people aim instead at winning, at looking consistent, or at being seen as right, and all three are compatible with being wrong for years. What marks somebody worth trusting is where they turn when those come apart.

Watch yourself in the next disagreement and notice what you are really pursuing. If new information would embarrass you, that is the moment the choice gets made. Saying that you had it wrong costs a few seconds and buys a standing that nothing else buys.
