It’s a specific kind of feeling, when my brain starts protecting itself against information that proves me wrong. Kind of like a real threat. It feels like I’m under attack, and I’m losing. I get subtly upset (because I’m a know-it-all and I want to be right), which is itself quickly reframed as anger, probably by that same mechanism. Probably much easier to admit that I’m angry because of “that guy!” than that I’m gonna be a crybaby because I’m wrong. But them’s the breaks, son.
I find it hard, and I wish I could say it gets easier, but it doesn’t. It sucks being wrong, and it’s humiliating.
I’d describe it as: at any moment you feel a flare of anger, try and ask yourself, what if you were wrong? If you find it hard to even engage in the thought experiment, that’s probably it. On a normal day you’d have no problem doing it. Try it now: it’s just a thought. Try it when you’re upset: it’s practically impossible.
