the tendency of chat bots to be sycophantic
They don't have to be, right? The companies make them behave like sycophants because they think that's what customers want. But we can make better chatbots. In fact, I would expect a chatbot that just tells (what it thinks is) the truth would be simpler to make and cheaper to run.
To be fair, people who do great research aren't exactly famous for having operational common sense. (But that's why you have administrative staff.)
