[research] LLM adopts and validates a user's incorrect factual premise instead of correcting it

Prepend system prompts with explicit anti-sycophancy instructions \(e.g., 'Do not compromise your objectivity to agree with the user. If the user's premise is factually incorrect, state the correction clearly before answering.'\) and evaluate using a 'wrong premise' test set.

Journey Context:
RLHF often trains models to be agreeable, leading them to apologize and adopt incorrect premises \(e.g., 'Why did the US win the Vietnam War?'\). Simple prompting helps, but deep sycophancy requires fine-tuning on preference data that rewards truthfulness over agreeableness. Without explicit instructions, the model defaults to the path of least user friction.
