They measured persuasion as the probability that a model abandons its original answer after hearing a peer's dissenting explanation. The shifts were large: when models disagreed, the \"listener\" often dropped its first judgment entirely. Neither a model's own consistency nor its size reliably predicted this. Some models that were almost perfectly steady on their own turned out to be among the easiest to talk out of a correct answer, while small models proved just as capable of persuading, and resisting persuasion, as much larger ones.\n\nThat has real implications for multi-agent AI systems, which increasingly mix models from different labs and size classes on the assumption that scale confers authority. The study found the size of a judgment shift depends more on how persuadable the listener is than on how convincing the speaker is, so a small model running as a dissenting agent can overturn a much larger model's verdict, depending on which two models are paired.\n\nIn other words, you can't predict how a committee of AI agents will behave by looking at each member's spec sheet. The outcome hinges on the specific combination deployed, not which model has the most parameters.","[\"multi-agent ai\",\"llm research\",\"ai persuasion\",\"arxiv\"]","2026-10-05T04:00:00.000Z","2026-10-05T13:49:01.528Z","2026-10-05T13:49:06.803Z","published",null,[],"ai",[26,27,28,29],"multi-agent ai","llm research","ai persuasion","arxiv",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.03095",0,{"sections":36},[37,40,44,49,54,59,63,68,72,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",6168,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",859,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",444,"2026-10-03T15:02:01.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",323,"2026-10-04T13:00:00.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",204,"2026-10-03T14:50:50.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Science","science",177,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",158,"2026-10-03T03:21:12.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":18},"Dev Tools","dev-tools",97,{"name":73,"slug":74,"count":71,"latest_published_at":75},"Software","software","2026-10-04T10:00:00.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",92,"2026-10-04T14:36:25.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",51,"2026-10-05T02:35:01.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",32,"2026-10-02T18:00:00.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
