[counterintuitive] Does RAG eliminate LLM hallucinations

Implement answer-grounding verification \(e.g., citation checking\) and context-prioritization instructions; RAG only reduces hallucination if the model actually attends to the retrieved context rather than overriding it with parametric memory.

Journey Context:
Devs assume giving the model documents forces it to use them. In reality, models suffer from 'context ignorance' or 'lost in the middle' effects, and may still rely on their pre-trained weights if the retrieved context conflicts with their parametric memory or is poorly formatted. RAG shifts the problem from 'hallucinating from scratch' to 'hallucinating from the provided text' or 'ignoring the provided text'.
