You can generally “convince” it to agree with anything, how difficult that is depends on how strongly it “knows” that what you say is wrong. Making it agree that violence is cool is harder than making it agree that 1+1=3 is harder than making it agree that <obscure chemical process> is <completely wrong explanation>.
I've had it go through a few cycles of "hey that's wrong" followed by another answer. Sometimes it finds the right answer eventually.
It also has told me that it doesn't learn from the chat, but I've seen it change its answers after discussion and going back to the original questions.
Isn't that a "generic" answer though? Like if you point out that something actually true is wrong, what does it say? (haven't tried)
