[research] Asking an LLM to 'review your answer for factual errors' without providing new external tools or context

Do not rely on self-correction loops for factuality unless the loop includes an external verification step \(e.g., a web search, code execution, or database lookup\). If no external tool is available, accept the initial answer, as self-reflection alone often justifies the initial hallucination.

Journey Context:
It is a common misconception that LLMs can self-correct their factual errors by 'thinking harder.' Without external feedback, the model's internal representation remains unchanged, and it will typically rationalize its initial \(potentially hallucinated\) output. Self-correction only works for formatting or style, not for grounding new facts.
