As the title says, how often do you admit you're wrong? Is it different when it's a factual dispute versus something more subjective?
I make an effort to concede early if I'm in error. I think because my mother almost never admits fault. She'll fall back to "that's not what I meant" or similar deflections first, and that's really annoying.
The last big factual error I made was about the distance of walking, and that's where I learned about Taxicab Geometry ( https://en.wikipedia.org/wiki/Taxicab_geometry ).
I think some people believe admitting fault is a sign of weakness, but I find it's more of a power move. It takes strength to do it, and people can tell when you're sweating and desperate. Usually it leads to resolving the conflict faster and cheaper, too.
(I expect some people will feel the urge to reply they're never wrong. I'll file that under never admits fault.)
I have a somewhat vivid memory of sprinting through NY Penn Station around midnight to get the last train home, back before I lived in the city. Was a deciding factor in me moving. Had to leave my friend's Halloween party at like 10 to get the last train.
