Researchers have developed a new protocol called Diverse Hypothesis Deliberation (DHD) to evaluate the value of messages in multi-agent reasoning systems, even when those messages contain incorrect answers. The DHD protocol measures a message's "trajectory value" by assessing whether its inclusion helps or harms subsequent reasoning, independent of its final answer's correctness. Experiments using GPT-OSS 120B and Gemma 4-31B-it models across various benchmarks revealed that "wrong but useful" messages are common and can significantly influence downstream reasoning positively. The findings suggest that focusing solely on answer correctness is insufficient, and DHD offers a method to identify valuable reasoning trajectories. AI
IMPACT This research could lead to more robust multi-agent AI systems by enabling them to better leverage useful reasoning, even from incorrect intermediate steps.
