This isolates what the researchers call trajectory value: whether a message actually helps later reasoning, separate from whether it was correct. Testing two open-source model families, gpt-oss-120b and gemma-4-31B-it, across five math and science benchmarks, they found wrong answers that improved the final result in every single benchmark-model pairing. Of the wrong answers that changed the final outcome at all, more than 40 percent changed it for the better, and repeat trials show this isn't noise (p=0.0002).\n\nThis matters because most multi-agent AI setups use confidence scores or majority agreement to decide which messages to trust, on the assumption that likely-correct answers are the only ones worth keeping. This research suggests that assumption quietly discards useful work. A wrong answer can still hand the system a solid decomposition of the problem or a correct constraint, and the study finds keeping the reasoning behind a wrong message helps more than keeping just its final (wrong) answer.\n\nIt's a small, open-model study, not a production system, but it points at the same lesson code review has always taught: a wrong conclusion built on sound reasoning is often more useful than a lucky right answer with no shown work.","[\"multi-agent-systems\",\"ai-research\",\"llm-reasoning\"]","2026-08-17T04:00:00.000Z","2026-08-17T06:42:55.955Z","2026-08-17T06:43:07.858Z","published",null,[],"ai",[26,27,28],"multi-agent-systems","ai-research","llm-reasoning",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.14375",0,{"sections":35},[36,40,44,49,54,59,64,69,74,79,84,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":39},"Security","security",435,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
