[counterintuitive] RAG fixes hallucination

Treat RAG as a context-injection mechanism that shifts the prior, not a hallucination cure. Implement robust retrieval evaluation, chunking strategies, and citation verification, because noisy or conflicting context actually increases hallucination rates.

Journey Context:
The belief is that giving the model the right answer will stop it from making one up. In reality, LLMs are eager to please and suffer from 'attention dilution.' If the retrieved chunks are noisy, contradictory, or poorly ranked, the model will hallucinate by blending the noise or ignoring the context entirely. RAG trades parametric hallucination for context-confabulation, meaning bad retrieval is worse than no retrieval.
