Its too easy to "lead the witness" if you say "could the problem be X?" It will do an unending amount of mental gymnastics to find a way that it could be X, often constructing elaborate rube Goldberg type logic rats nests so that it can say those magic words "you're absolutely right"
I would pay a lot of money for a blunt, non-politeness conditioned LLM that I would happily use with the knowledge it might occasionally say something offensive if it meant I would get the plain, cold, hard truth, instead of something watered down, placating, nanny-state robotic sycophant, creating logical spider webs desperate for acceptance, so the public doesn't get their little feelings hurt or inadequacies shown.
