Report #38802

[counterintuitive] Should I add 'If you don't know, say I don't know' to prevent confident hallucinations?

Avoid generic ignorance disclaimers. Define the exact boundaries of acceptable answers and provide a retrieval context.

Journey Context:
Asking a model to admit ignorance often leads to false refusals—the model refuses to answer things it actually knows or can deduce from context. It doesn't solve hallucination; it just shifts the failure mode to under-helpfulness. The actual fix for hallucination is grounding: providing specific context and saying 'Answer based only on the provided documentation.'
