Report #84909

[research] RAG system exclusively relies on the top-ranked document, even if it is irrelevant or contradictory to lower-ranked, more accurate documents

Instruct the model to synthesize information across all provided documents, and explicitly ask it to resolve conflicts between documents if they disagree.

Journey Context:
Position bias in LLMs causes them to overweight the first piece of context provided. In RAG, if the retriever returns a highly ranked but factually incorrect document, the LLM will blindly trust it. Prompting the model to compare and contrast documents mitigates this positional bias and forces cross-document reasoning.
