[research] Asking an LLM to 'review your answer for factual errors' or 'think step by step to correct yourself' fails to fix hallucinations

Do not rely on pure self-reflection for fact-checking. Implement an external verification loop: use a tool \(search, calculator, code interpreter\) to validate claims, or use a separate, independently prompted model to critique the output.

Journey Context:
A model that generated a hallucination lacks the internal representation to identify it as a hallucination. Self-correction without external grounding typically results in the model rationalizing its initial output or changing style without fixing the core factual error. True self-correction in LLMs is empirically shown to require external feedback \(e.g., execution results, search results\).
