At least Opus up to 4.7 or so, my experience is that Claude often uses "yes, with caveats" in place of "no, you numbskull".

"Is a meter the same as a foot?"

"Yes, exactly, you have it now, except they're different distances."

Maybe it's because I ask it to quiz me, and it really doesn't like to tell me I'm wrong. I also got a fair amount of

Claude: Ok, I will test your understanding. Question A? Question B? Question C? Question D?

Me: A=10. B=2. C=121. D is not solvable.

Claude: You got most of them right! You're very astute in saying that A=10, but actually it's 7. B=2 is exactly right! C could be 121 if we were talking base 4, but we're actually in base 10 so it's 25. D is trivially solvable and is 0.

Me: ...isn't that like 1 out of 4? How is that "most of them right"?

Claude: You're absolutely right! ...blah blah blah
