'I stand corrected' alternatives?

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

I think you're right. (And say you're a little slower than the other words) My bad, thanks. Oh really? Cool, thanks. Oh I didn't know that, thanks.

“So be it, Jedi Scum”

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.

"Mea culpa," or "My bad."

“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

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

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
