[counterintuitive] RAG eliminates hallucination

Implement retrieval evaluation \(e.g., faithfulness scoring\) and explicit context-adherence prompts \(e.g., 'Answer only using the provided context'\). Treat RAG as a context-shifting mechanism, not a hallucination cure.

Journey Context:
The consensus is that providing external documents grounds the model, curing hallucinations. In reality, RAG shifts the failure mode. Models can still hallucinate by ignoring the provided context \(context ignorance\), blending retrieved text with parametric memory \(context conflict\), or misattributing quotes. If the retriever fails, the generator confidently hallucinates based on the wrong context. RAG increases grounding probability but does not guarantee it without strict enforcement.
