'I stand corrected' alternatives?

"Mea culpa," or "My bad."

Fair point

Touché and point taken I feel are pretty close.

I was mistaken. Clearly I was wrong.

“Touché” can be used when someone makes a point that disproves or weakens one’s own stance.

"You're right" i guess?

I always liked “Duly noted” (if the context is that someone is correcting you). Sounds so proper lol

What everyone is saying ("touchè", "point taken", etc.) seems more like what you would say for "you make a good point" and not "I repectfully acknowledge I was wrong." which are two very different things.

twist it into "i sit corrected"

You're right. Oh, I get it, now. I see your point. I was mistaken. It turns out that I was, in fact, wrong on this point.

“Sorry, I was wrong about that”

“Good call”

The French say "je mourrai moins bête", which means "I will die less stupid".   I love this one 

Truue

Touché is French, but it has worked its way into anglophone usage.

* I was mistaken * You're right * I was wrong

So many people have an aversion to saying "you're right" More people ought to do it

That checks out That tracks Today I learned

My bad, thanks

Well damn, burn, ouch. All work for the younger generations

“So be it, Jedi Scum”

I miss spoke I acknowledge my mistake I concede the point My bad Idioms I would say: Eat my words Backtrack on that Do a 180
