Report #90239

[counterintuitive] Adding phrases like 'Do not hallucinate,' 'Ensure you are accurate,' or 'Do not make mistakes' to prevent errors

Provide positive grounding constraints: 'Only use the provided context,' 'If the answer is not in the text, return Not found,' or provide reference tools \(RAG\) for the model to lookup facts.

Journey Context:
Models do not have a binary 'hallucinate' switch they can flip based on an instruction. Telling a model not to hallucinate often increases hallucination because the token 'hallucinate' primes the model for hallucination-like patterns. Positive constraints \(what to do\) are computationally actionable, whereas negative constraints \(what not to do\) are vague and lack a concrete token path to follow.
