The study ran a targeted suite of 13 test items through 784 forward passes across ten counterbalanced conditions, built specifically to separate the effect of a document's framing (official guideline versus fresh update) from its reading position (first versus second). Framing won. When the two cues pointed in different directions, the model's answer tracked the source's tone far more than whether it was read first or second.\n\nThat matters for anyone building retrieval systems that hand a model two sources and hope it picks the right one. The model does have a built-in preference for whatever it reads first, but the same paper found that bias swings by a factor of 5 or more depending purely on wording, and it spikes hardest when the two documents are near-identical templates. Vary the phrasing between sources and the positional bias fades, which suggests uniform source formatting is a bigger risk than document order itself.\n\nTranslation for anyone stacking documents into a RAG pipeline: skip the officious tone if you want the model weighing evidence instead of letterhead.","[\"ai\",\"gemma\",\"llm-research\",\"arxiv\"]","2026-09-28T04:00:00.000Z","2026-09-28T06:08:23.261Z","2026-09-28T06:08:29.308Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Add explicit sourcing for the statistics — name the source as an arXiv paper (with paper title\u002FID and posting date) rather than the vague 'researchers ran,' since specific figures like 13 items, 784 forward passes, and the 5x variance need a cited source per our sourcing standard.","resolved","ai",[30,32,33,34],"gemma","llm-research","arxiv",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.30716",0,{"sections":41},[42,45,49,54,59,64,68,73,78,83,88,93,97,102],{"name":43,"slug":30,"count":44,"latest_published_at":18},"AI",4689,{"name":46,"slug":47,"count":48,"latest_published_at":18},"Security","security",758,{"name":50,"slug":51,"count":52,"latest_published_at":53},"Policy","policy",399,"2026-09-27T18:39:02.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Deals","deals",261,"2026-09-27T15:30:35.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Hardware","hardware",188,"2026-09-27T20:46:36.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":18},"Science","science",148,{"name":69,"slug":70,"count":71,"latest_published_at":72},"Consumer Tech","consumer-tech",135,"2026-09-26T14:30:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Dev Tools","dev-tools",84,"2026-09-26T04:20:58.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":94,"slug":95,"count":91,"latest_published_at":96},"General","general","2026-09-26T17:02:42.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":103,"slug":104,"count":105,"latest_published_at":106},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
