[research] Connecting two true facts with a false intermediate step or relationship in multi-hop reasoning

Decompose multi-hop questions into explicit, verifiable single-hop sub-queries. Execute sub-queries independently via search/retrieval, then synthesize the results, rather than asking the model to reason across hops purely from parametric memory.

Journey Context:
When asked a complex question requiring connecting multiple facts \(e.g., 'Did the founder of company X attend the same college as the CEO of company Y?'\), models often hallucinate the connection even if the individual entities are real. The HotpotQA benchmark demonstrated that naive multi-hop prompting leads to high rates of bridging hallucinations. Fact decomposition \(Chain-of-Note or iterative retrieval\) forces the model to ground each hop independently.
