Report #101243
[counterintuitive] RAG eliminates hallucinations
Design RAG as a hallucination-reduction system, not a hallucination-elimination system. Add retrieval relevance scoring, citation verification, and a 'not in context' fallback for questions the retrieved documents cannot answer.
Journey Context:
The belief that grounding the model in retrieved documents removes hallucinations ignores retrieval hallucinations \(wrong chunks\), context confusion \(model cites the wrong passage\), and confabulation when the context is insufficient. Research shows RAG can still produce unsupported claims. The accurate mental model is: good retrieval lowers hallucination rate, but only explicit citation checks and graceful refusal close the remaining gap.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
