To rise from error to truth is rare and beautiful.

Changing your mind in public costs something, which is why so few people do it. The move requires admitting you argued for the wrong thing, possibly for years, and accepting whatever that does to how you are seen, and most would rather keep defending a position than pay that. Watching somebody do it well is genuinely moving for exactly that reason.

Give yourself the practice at low stakes. Say out loud this week that you were wrong about something small and specific, with no hedging and no explaining it away. The capacity gets easier with use and is rare enough to be noticed.
