Report #90288

[research] LLM expresses high confidence when its internal knowledge is insufficient or outdated

Use explicit self-assessment prompting \(e.g., 'Rate your confidence from 1-10. If < 8, state I don't know'\) and enforce abort/research conditions for low-confidence generations.

Journey Context:
Standard RLHF trains models to sound confident. Verbalized confidence is often poorly calibrated. However, recent work shows that prompting for explicit confidence and allowing a fallback to tool-use or 'I don't know' significantly reduces hallucination rates without hurting overall task completion.
