Report #5446
[research] RAG system generates a factually correct answer that is not supported by the retrieved context
Optimize for faithfulness \(context adherence\) over external factuality. If the context lacks the answer, explicitly state the limitation rather than introducing external knowledge.
Journey Context:
There is a tension between faithfulness \(is the answer supported by the context?\) and factuality \(is the answer true in the real world?\). A model might use parametric memory to give a correct answer, but this defeats the purpose of RAG \(verifiable, grounded answers\) and breaks trust in citation systems. RAGAS and other RAG eval frameworks penalize low faithfulness even if factuality is high.
