[research] LLM doubling down and fabricating justifications when challenged on a factual error
When verifying a fact, do not ask the model 'Are you sure?' or 'Why is that?'. Instead, provide the correct fact as a premise and ask it to regenerate the solution based on the new premise, or use an independent verification tool.
Journey Context:
Challenging a model on a hallucination often triggers 'sycophantic rationalization' or 'doubling down,' where the model invents fake logic to defend its initial incorrect output. The model treats the user's challenge as a debate to be won rather than a factual correction. Re-grounding or using external tools bypasses the model's defensive generation and forces a reset.
