I think it’s a healthy thing to do to admit when your wrong as it places importance on truth rather than self image.
Some examples:
I thought pay-per-view was paper-view because you had to fill out a form to watch it.
This morning I insisted there was a noise outside to my partner and it was in fact the refrigerant in the fridge gurgling.
I thought the cat wanted to be pet— it did not.
I recently thought geese just ate bugs in the grass and even said so, but apparently they graze on the grass. I admitted my mistake when I found out a couple days later.
I’ve never had a geese-observation opportunity but now I know they eat grass and the bugs in it, so thanks!
