[counterintuitive] Does Retrieval-Augmented Generation \(RAG\) eliminate hallucination?

Treat RAG as a context-shifting mechanism, not a hallucination cure. Implement explicit grounding checks and prompt the model to state 'I don't know' if the retrieved context lacks the answer.

Journey Context:
Developers assume providing external documents forces the model to stick to facts. In reality, models still hallucinate within the context window, misinterpreting or contradicting the retrieved text. Furthermore, irrelevant or contradictory retrieved chunks \(distractors\) can actually increase hallucination rates by confusing the attention mechanism, causing the model to blend context with parametric memory.
