Report #62726

[research] LLM ignores the retrieved context document and answers using its internal, potentially outdated parametric memory

Use attention-guiding prompts \(e.g., 'Answer using ONLY the provided context. If the context does not contain the answer, say I don't know'\) and evaluate with context-ablation studies.

Journey Context:
When retrieved context conflicts with the model's strong prior \(e.g., a common misconception or outdated fact\), the model often overrides the context. This is a known failure mode in RAG where retrieval success does not guarantee generation faithfulness. Simply providing context is insufficient; the model must be instruction-tuned to prioritize context over priors.
