A human that makes a mistake, catches it, corrects it and apologizes is someone I'd much rather interact with than someone that makes a mistake, catches it, and doubles down on the mistake that I then later discover the issue would be the person I would not be my go to source.

Mistakes happen. If they are honest mistakes, then we can deal with it. If they are deliberate mistakes, well, we can deal with that too but in a different manner. The problem that I have is answering something in a confident manner when it's really a hedge to not sound unsure. People apparently have issues with an unsure bot. I'd much rather have a response like, "I'm not positive, but I think PLA is less dense than ABS" for the wiggle room of being able to come back later with "So technically, PLA is more dense than ABS". Even if the bot doesn't figure it out, by phrasing that way, you're clued in on what to fact check
