[counterintuitive] Implementing RAG eliminates model hallucinations

Treat RAG as context grounding, not a hallucination cure. Implement explicit citation verification and self-correction loops, as irrelevant retrieved context can cause more convincing hallucinations.

Journey Context:
The belief is that giving the model the right answer in context stops it from making things up. In reality, LLMs suffer from attention dilution and the 'lost in the middle' phenomenon. If the retrieved documents don't contain the answer, or if the prompt doesn't strictly enforce answering only from context, the model will happily hallucinate using its parametric memory while sounding highly confident. RAG shifts the failure mode from making things up from scratch to misrepresenting the provided text.
