[counterintuitive] RAG \(Retrieval-Augmented Generation\) eliminates hallucinations

Treat retrieved context as untrusted input; enforce citation verification, implement self-consistency checks, and use retrieval confidence scoring to filter low-quality documents before they reach the LLM.

Journey Context:
RAG does not fix hallucination; it shifts the failure mode from parametric memory confabulation to context-conflicting hallucination. If the retriever fetches irrelevant or contradictory documents, the LLM will confidently hallucinate based on that context. Furthermore, the 'lost in the middle' phenomenon means LLMs frequently ignore retrieved context placed in the middle of the prompt, falling back on their parametric memory and hallucinating anyway.
