Report #73875
[counterintuitive] RAG fixes hallucination
Implement strict relevance scoring and context window management in RAG; irrelevant or conflicting retrieved documents will increase hallucination rates rather than reduce them.
Journey Context:
The assumption is that giving the model ground-truth context forces it to answer from that context. In reality, LLMs suffer from the 'lost-in-the-middle' effect and are easily confused by noisy, conflicting, or tangential chunks. If the retriever pulls low-relevance documents, the model might hallucinate by stitching together unrelated facts from the context, or use the context as a springboard for further confabulation. RAG only reduces hallucination if the retrieval is highly precise and the context is clean.
