Saying “I was wrong” out loud grows you more than a year of being right.

Being right teaches you almost nothing, because it only confirms what you already had. Admitting an error forces a real update, and saying it aloud makes the update stick in a way that private acknowledgement never does. It also costs something, which is precisely why it works.

Find the smallest thing you have been quietly wrong about and say so to the person involved, with no long explanation attached. Notice how little actually happens to you. The second time is easier, and the habit changes how people talk to you.
