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 thought hillary was going to win the 2016 election.
Same, and I also thought Kamala would win because our voters couldn’t possibly be dumb enough to elect the dipshit fascist again after how badly it went the first time and how he was talking about all the awful shit he’d do.
I was wrong to put any faith in my fellow citizens, clearly.
