[research] Factual accuracy plummets when the LLM must chain multiple reasoning steps together

Decompose multi-hop questions into explicit, single-hop sub-queries. Verify the factual output of each step independently before passing it to the next step, rather than asking for the final answer in one generation.

Journey Context:
Error compounding in multi-hop reasoning is severe. If step 1 has a 95% accuracy and step 2 has 95% accuracy, the chained accuracy is ~90%. In practice, it is worse because early errors drastically shift the context for subsequent steps. Atomic, verified decomposition prevents cascading hallucinations.
