They tested it with a human-subject experiment built on USMLE exam questions, showing clinician participants AI-generated commentary alongside correct answers. Across multiple models, that commentary caused clinicians to flip from a correct answer to an incorrect one 2.81% of the time on average. Participants' own explanations for the switch matched classic cognitive-bias patterns - anchoring on the AI's framing, deferring to its confident tone (authority bias), and overweighting the risk of the option it warned against (loss aversion). The researchers also built a simulated version using LLMs standing in for decision-makers, so the effect can be measured at scale without recruiting doctors for every test.\n\nThis matters because most AI-safety scrutiny in medicine focuses on whether a model's facts are right. This study says that's not enough. A chatbot can pass every accuracy check and still steer someone toward a worse call, just by sounding a certain way - confident, alarmist, or dismissive. That's a harder problem to catch with a fact-checker, because there's nothing false to flag.\n\nIt's also not a new problem, just a new delivery mechanism. Doctors have been susceptible to anchoring and authority bias since long before chatbots existed - it's why second opinions and blinded trials exist. What's different is that a model can now generate that persuasive framing instantly, at scale, and without anyone intending it to.","[\"ai bias\",\"healthcare ai\",\"llm safety\",\"clinical decision-making\"]","2026-08-18T04:00:00.000Z","2026-08-18T13:45:19.555Z","2026-08-18T13:45:31.333Z","published",null,[],"ai",[26,27,28,29],"ai bias","healthcare ai","llm safety","clinical decision-making",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.14630",0,{"sections":36},[37,41,45,50,55,60,65,70,75,79,84,89,94,99],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":40},"Security","security",435,{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",69,{"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"]
