Report #96538

[counterintuitive] Using negative constraints like 'Do not hallucinate' or 'Do not make mistakes' to improve accuracy

Provide grounding context \(RAG\), define explicit fallback behavior for uncertainty \(e.g., 'If the answer is not in the context, return Unknown'\), and use structured outputs.

Journey Context:
Negative constraints are poorly understood by LLMs; they often focus on the forbidden concept \(hallucination\) and paradoxically increase its likelihood. Modern models need positive, actionable instructions for handling uncertainty and architectural constraints \(like retrieval\) to prevent hallucination, not magic words. Telling a model not to hallucinate is like telling a human not to think of an elephant.
