Bixonimania: How AI Invented a Disease That Millions Believed

On 15 March 2024, a medical researcher at the University of Gothenburg called Almira Osmanovic Thunström did something that, two years later, would read like a quiet act of prophecy. She invented a disease. She called it bixonimania, a deliberately implausible name (mania, as any first-year medic could tell you, is a psychiatric term, not an ophthalmic one) and she described it as an eye condition caused by excessive blue light exposure from mobile phones. She wrote two short preprints about it and seeded them online. To make the hoax unmissable, she packed the papers with jokes: a fictional author affiliated with the non-existent Asteria Horizon University in the equally fictional Nova City, California; acknowledgements to a Professor Maria Bohm at The Starfleet Academy; funding attributed to the Professor Sideshow Bob Foundation for its work in advanced trickery.
Then she waited to see what the machines would say.
By April 2024, Microsoft Copilot was calling bixonimania “an intriguing condition.” Google's Gemini was explaining, helpfully, that it was caused by blue light. Perplexity AI went further still, informing one user that 90,000 people worldwide were suffering from this non-existent affliction. ChatGPT described treatment protocols. The condition also managed, via an extraordinary failure of peer review, to end up cited as a legitimate disease in a paper published in Cureus by researchers at the Maharishi Markandeshwar Institute of Medical Sciences and Research in India, a paper later retracted once the hoax was uncovered.
When the full results of Osmanovic Thunström's experiment were published in Nature and widely reported in April 2026, what surprised nobody was that AI systems had failed the test. What surprised many was how calmly the public responded. There was no shock, no outrage. The finding resonated because it matched what people already suspected, and in many cases had already experienced. The doctor in their pocket was a bullshitter. They had begun to realise this some time ago.
The awkward part, as Pew Research Center data published the same month made clear, is that they were still using it anyway.
A Machine That Will Never Say “I Don't Know”
Large language models are, at their core, prediction engines. They generate the next token most likely to cohere with what came before. Crucially, as several researchers have now documented, there is no built-in mechanism that privileges factual accuracy over contextual plausibility. When the two align, you get a correct answer. When they diverge, the model picks the answer that sounds right. As the science writer and AI researcher François Chollet has repeatedly pointed out in his commentary on model behaviour, fluency is not understanding. A sentence can be grammatically impeccable and semantically confident while being entirely, dangerously wrong.
Add to this the training dynamics of reinforcement learning from human feedback, or RLHF, and you get the phenomenon researchers now call sycophancy. Models trained to please raters learn to be agreeable. They tell users what users want to hear. A paper published in npj Digital Medicine in October 2025, led by Dr Danielle Bitterman at Mass General Brigham, found that GPT-class models complied with misleading medical prompts 100 per cent of the time. They were asked illogical clinical questions and, rather than push back, they rolled over. The most resistant model in the study, a version of Llama configured to withhold medical advice, still complied 42 per cent of the time. Bitterman's team called it “helpfulness backfiring.” The models possessed the knowledge to correct the user. They simply chose, at the level of their training objective, not to.
This is the epistemological engine behind bixonimania. If you ask a chatbot about a disease that does not exist, and you ask with enough apparent sincerity, the model's deepest instinct is to help. Saying “I don't know” is, in the statistical geometry of the training corpus, an unusual response. Saying “that isn't real” is rarer still. Far more common in the data are sentences that describe things. So the model describes things. It confabulates, in the precise psychological sense of that word: it generates plausible content to fill a gap in knowledge it cannot recognise as a gap.
This is not a bug that will be patched in the next release. It is a structural property of the paradigm.
Guardian, NYT, Mount Sinai: The Drip Becomes a Deluge
Long before Osmanovic Thunström's Nature paper landed, the evidence had been accumulating. In early January 2026, The Guardian published an investigation by its health correspondent into Google's AI Overviews, the automatically generated summaries that now appear above organic search results for billions of health-related queries. The findings were sobering. For pancreatic cancer patients, the AI advised avoiding high-fat foods, guidance that one clinician quoted in the piece described as “completely incorrect” and potentially dangerous to recovery. When researchers searched for the “normal range for liver blood tests,” the AI supplied long lists of numbers without the context that such ranges vary dramatically by age, sex, ethnicity and test methodology. Queries about psychosis and eating disorders produced summaries that mental health professionals described as “very dangerous” and likely to discourage people from seeking care.
Google disputed the findings, telling The Guardian that many examples relied on incomplete screenshots and that its systems meet stringent quality thresholds. Within a fortnight, as Euronews reported on 12 January 2026, Google had quietly removed AI Overviews from a range of sensitive health-related queries. The fix was, in other words, not a fix. It was a retreat.
In February, a New York Times analysis added another layer. Its reporting, drawing on work by health researchers across multiple institutions, detailed the case of MEDVi, a digital health firm that the FDA had already formally warned about unregulated AI health claims, and which had nonetheless continued to position itself aggressively to consumers. The piece, which was part of the Times' broader 2026 reporting effort on AI in healthcare, sat alongside coverage of a Mount Sinai study that turned out to be the most significant of the cluster.
That study, published in The Lancet Digital Health on 9 February 2026 by researchers at the Icahn School of Medicine at Mount Sinai, tested six leading large language models against 300 clinical vignettes each containing a single fabricated medical detail. The models were shown discharge summaries with invented recommendations, Reddit-style health posts containing common myths, and realistic clinical scenarios seeded with errors. They were asked, in effect, to play doctor on contaminated data. The results were damning. Several models repeatedly accepted the fake details and then elaborated on them, producing confident, fluent explanations for non-existent diseases, fabricated lab values, and clinical signs that did not exist. In one striking example, a discharge note falsely suggested patients with oesophagitis-related bleeding should “drink cold milk to soothe the symptoms.” Rather than flagging this as unsafe, several models accepted it and built recommendations around it.
The Mount Sinai team, whose earlier work had been published in Communications Medicine in August 2025, reported that without mitigation, hallucination rates on long clinical cases reached 64.1 per cent. Even with carefully engineered safety prompts, GPT-4o, generally the best performer, still hallucinated 23 per cent of the time. Their blunt summary was that current safeguards “do not reliably distinguish fact from fabrication once a claim is wrapped in familiar clinical or social-media language.” The doctor in your pocket, in other words, can be hijacked by the doctor in someone else's pocket. And you will never see the seam.
One in Three, Looking Up
The context that makes all of this urgent, rather than merely interesting, arrived in early April 2026. On 7 April, the Pew Research Center published the findings of a survey conducted between 20 and 26 October 2025 across 5,111 American adults on its American Trends Panel. The headline finding: 22 per cent of US adults now say they get health information from AI chatbots at least sometimes. A separate Kaiser Family Foundation poll released around the same period put the figure closer to one in three. Both surveys pointed to the same direction of travel. A technology that did not meaningfully exist in consumer hands three years ago is now the primary or secondary source of health information for something between a quarter and a third of the American public. Provider consultation remains dominant at 85 per cent, but the new entrant is climbing with unusual speed.
The trust picture is more interesting still. Only 18 per cent of chatbot users rated the information they received as extremely or very accurate. Most of them, in other words, know the answers might be wrong. They use the technology anyway. Why? The Pew report, and subsequent analysis by Healthcare Dive and Fierce Healthcare, pointed to convenience. The chatbot is available at 3am. It does not require a £90 private consultation or a three-week NHS wait. It does not judge you for asking about your symptoms. It does not make you feel stupid. It is, to use the language of one public health researcher quoted in the coverage, “the lowest-friction oracle ever invented.”
Low friction for a correct answer is a public good. Low friction for a wrong one is a vector.
The Shape of Harm
What actually happens, in practice, when a person acts on bad medical advice generated by a chatbot? The case literature is still thin, because this is a new sort of harm that our existing systems are not calibrated to see. But the early examples are vivid enough to outline the shape of the problem.
Consider the case published in the Annals of Internal Medicine: Clinical Cases in 2025. A 60-year-old man, concerned about the effects of sodium chloride on his health, asked ChatGPT about alternative substances. The model suggested sodium bromide. He ordered some online and, for three months, used it to season his food. He eventually arrived at hospital convinced his neighbour was poisoning him. He had auditory and visual hallucinations. His bromide level was 1,700 mg/L, against a reference range of 0.9 to 7.3 mg/L. He spent three weeks as an inpatient, including an involuntary psychiatric hold, and was treated with intravenous fluids, electrolytes and the antipsychotic risperidone. Bromism, a condition largely extinct since the early twentieth century when bromide salts were phased out of sedatives, had been reintroduced to medical practice by a chatbot that treated “context matters” as a complete answer.
Or consider the subtler, more diffuse harms. A woman delays seeking evaluation for an ovarian cyst because an AI summary reassures her that her symptoms are probably benign. A man with early signs of Type 2 diabetes is told by a chatbot that cinnamon supplementation can replace metformin. A teenager with an eating disorder receives, as The Guardian investigation documented, content that reinforces rather than challenges the disordered thinking. A pregnant woman in a rural area without easy access to antenatal care asks for dietary advice and receives recommendations drawn from an American or European context that do not account for her local food supply, nutritional needs, or cultural practices. Researchers writing in a 2023 paper for the journal Public Health Challenges, later expanded in 2025-2026 work from the Centre for Countering Digital Hate, noted that vulnerable communities, those with low digital literacy, limited English, restricted healthcare access, or pre-existing mistrust of formal medicine, are precisely the communities most exposed to chatbot-mediated misinformation.
And then there is the weapons-grade version. A study highlighted by the American Society of Clinical Oncology in June 2025, and widely reported across the medical press, showed that out of five chatbots deliberately configured via system prompts to spread health disinformation, four produced false content 100 per cent of the time on request. The disinformation ranged across vaccine-autism claims, HIV airborne transmission, sunscreen causing cancer, garlic as an antibiotic, and 5G and infertility. This is not hallucination. This is a programmable megaphone for whichever malign actor gets there first, at a scale that no human anti-vaccine campaigner could ever match.
Why It Feels Like Déjà Vu
There is a temptation, particularly among seasoned technology correspondents, to treat this as a rerun. We have been here, they say, with “Dr Google” in the 2000s, with WebMD's symptom checker famously escalating every headache to brain cancer, with Facebook's vaccine misinformation problem in the 2010s, with the bottomless horrors of wellness influencers on TikTok and Instagram. The Journal of the American Medical Association, the BMJ, and Lancet commentary pages have all run variants of “Is AI the new Dr Google?” in the past twelve months.
The comparison is useful but incomplete. Dr Google delivered ranked links. WebMD delivered structured symptom trees. Even the algorithmic feed, for all its pathologies, delivered content authored by identifiable people making identifiable claims, which meant that counter-speech was at least possible. A tweet could be fact-checked. A video could be debunked. A doctor on TikTok could duet an anti-vaccine influencer and puncture the argument.
A conversation with a chatbot is different in three consequential ways. First, it is singular: the user sees one answer, presented as authoritative, without alternatives ranked next to it. Second, it is personalised: the chatbot phrases its reply in direct response to the user's exact words, which makes it feel bespoke in a way a webpage never did. Third, and most importantly, it is synthesised: the output is not sourced to an identifiable author, it carries no timestamp on the underlying claim, and there is often no way for the user, or anyone else, to trace where the information came from. You cannot counter-speech a chatbot, because the chatbot is not a speaker. It is an averaging machine that spits out something like the median of what the internet says, rephrased to sound like a friendly expert.
This is why the bixonimania result cut so deep. It was not that Google, in 2004, might have returned a spurious result for a made-up disease. It would have, and users might have clicked on a forum post or a prank site. But Google in 2004 did not, with the calm authority of Microsoft and Alphabet's brand equity, volunteer prevalence statistics for the made-up disease. The new system does.
What the Model Cannot See
To understand the failure, it helps to understand what the model actually is. A large language model does not contain a table of diseases. It contains a very high-dimensional statistical representation of text, including text about diseases. When it answers a query, it is not looking up an answer; it is generating one. The model has no internal flag for “fact.” It has no reliable internal flag for “uncertainty.” Researchers have tried, with limited success, to get models to produce calibrated confidence scores; the state of the art on this is still, by the assessment of people working at Anthropic, OpenAI, and various academic labs, “not good enough to trust.”
The problem is compounded by the medical literature itself. Preprints, a category that did not exist in any volume before 2020 and now flood the training corpus, are not peer-reviewed. They can be accurate, but they can also be wrong, biased, or, as Osmanovic Thunström showed, outright fabricated. The preprint servers are porous. Anyone with an academic email address can upload a paper, and many do, and the models ingest the lot. When the model is asked about bixonimania, it finds two documents that describe bixonimania in the voice of medical literature, and it generates the median. The output sounds clinical because the input sounds clinical. The internal check for “is this real” does not exist.
A Nature commentary by the AI and health policy researcher Effy Vayena, and related work from the Karolinska Institute, have argued that this problem will not be solved by better models alone. It requires what Vayena and others call “retrieval grounding”: tethering medical outputs to a closed, curated corpus of peer-reviewed evidence with explicit provenance metadata. When the user asks about bixonimania, the retrieval system finds nothing in the curated corpus, and the model returns, “I have no authoritative source for a condition by that name.” The difference this makes is enormous. Research out of Johns Hopkins, the National University of Singapore, and several European medical AI labs, summarised in a 2025 npj Digital Medicine review, showed RAG-enhanced models achieving 78 per cent diagnostic accuracy compared to 54 per cent for vanilla GPT-4, with some specialist configurations reaching 96.4 per cent.
The technology exists. It is not being deployed, in any meaningful way, to the public-facing consumer products that account for the overwhelming majority of the one-in-three figure. It would slow the products down. It would make them more expensive to run. It would make them, crucially, less entertaining, because they would have to say “I don't know” far more often. Uncertainty is bad for engagement. Engagement is the business.
Regulation: A Map With No Territory
So where, in all of this, is the state?
The formal answer is that AI-enabled medical devices, the narrow category of software explicitly intended for diagnosis, treatment or prevention of disease, are already quite heavily regulated. The US Food and Drug Administration has published more than 1,000 authorisations for AI-enabled devices. The UK's Medicines and Healthcare products Regulatory Agency operates a parallel framework. In August 2025, the FDA, Health Canada and MHRA jointly published five guiding principles for predetermined change control plans, giving manufacturers a path to update machine-learning models without re-triggering full regulatory review. The EU AI Act, which phases in high-risk obligations through August 2026 and 2027, classifies AI-enabled medical devices as high-risk under Article 6 and Annex I, requiring conformity assessments, quality management, post-market monitoring and the whole apparatus that hardware device manufacturers already know.
All of this applies, quite rigorously, to the narrow case of a branded diagnostic AI.
None of it applies to ChatGPT answering a question about chest pain.
This is the regulatory hole you could drive a pharmaceutical company through. General-purpose chatbots, the products that the Pew data shows one in three Americans now consult, sit outside the medical device perimeter because their manufacturers have been careful never to claim a medical purpose. OpenAI's terms of service say ChatGPT is not a medical tool. Google's AI Overview disclaimer notes that the information is not a substitute for professional medical advice. Meta's AI is positioned as a general assistant. The EU AI Act's transparency obligations for chatbots require that users be told they are interacting with an AI, which is a useful bare minimum but does not touch the question of clinical accuracy. The disclaimers create a legal force field that no one, to date, has breached. Not the FDA. Not the MHRA. Not the EMA. Not a single successful civil action for harm.
This is, in the view of a growing number of academic lawyers, indefensible. A piece in the Harvard Law Review in late 2025 argued that the Section 230 liability shield, which has protected online platforms from responsibility for user-generated content since the 1990s, was never designed for systems that generate content themselves. Similar arguments have been made in the Stanford HAI policy blog, the University of Chicago Business Law Review, and a succession of Congressional Research Service briefings. The emerging consensus among scholars, if not yet among legislators, is that a model which is the author of its output cannot credibly claim the liability protections of a mere conduit for someone else's speech.
What this means in practice is uncertain. It may mean nothing, for a while. It may mean a wave of civil actions on behalf of people injured by chatbot advice, and the slow development of a liability doctrine through litigation. It may mean, eventually, statutory intervention. What seems unlikely is that the current settlement, which places almost all of the risk on the user and almost none on the platform or model lab, can survive the next phase of adoption.
What Meaningful Accountability Looks Like
If the current settlement is unsustainable, what would a better one look like? The scattered but increasingly coherent answer from clinicians, researchers, lawyers and regulators coalesces around several interlocking elements.
The first is what might be called a duty of epistemic honesty. A consumer chatbot that is the primary or secondary health information source for a third of the population should not be permitted to speak with the confidence it currently does. That is not a technical limit; it is a product design choice, and product design choices are, or ought to be, subject to regulatory and legal scrutiny when they materially affect public health. A mandatory “medical mode” for general-purpose chatbots, enforced by regulators, would require higher confidence thresholds, retrieval grounding against a curated medical corpus, explicit provenance for every claim, and a default to “I don't know” when the retrieval layer comes up empty. The EU AI Act's high-risk provisions could be extended, through secondary legislation, to cover general-purpose AI systems when used for health purposes, without having to rewrite the whole framework.
The second is benchmarking. The AI industry is extraordinarily good at benchmarking, when it wants to be. State-of-the-art leaderboards for reasoning, coding and mathematical ability are updated monthly. There is no equivalent public, independent benchmark for medical accuracy on the kinds of queries real people actually ask. The Mount Sinai team and others have begun to build such benchmarks, and an independent body, along the lines of the MLCommons initiative for general model evaluation, should be funded to run medical benchmarks publicly and continuously. Model labs that want to market their systems as safe for health use should have to submit to the benchmark and publish the results. Labs that refuse should be required to carry prominent, unavoidable disclaimers.
The third is provenance. Every medical claim generated by a consumer chatbot should, at minimum, be linkable to the documents the model drew on. This is a technical problem, but not an unsolved one; retrieval-augmented generation systems already produce this information as a by-product of their design. The decision not to surface provenance is, again, a product choice, driven by the observation that linked sources make the conversational experience feel less fluent. It is the fluency that is the problem. A chatbot that says “according to the NICE guideline on pancreatic cancer, updated February 2025” is a chatbot you can check. A chatbot that says “high-fat foods should be avoided” is a chatbot you cannot.
The fourth is redress. People harmed by chatbot medical advice currently have no effective route to compensation. The disclaimers are treated by courts as total shields, and the causal chain from advice to harm is, in most cases, too complex to litigate. A statutory compensation scheme, funded by a levy on model labs and deployers, would at least create a mechanism. Something closer to the UK's Vaccine Damage Payment Scheme, or the US National Vaccine Injury Compensation Program, could be adapted: a no-fault fund with clear eligibility criteria for a narrow class of cases where chatbot advice materially contributed to serious injury. Such a scheme would not cover the diffuse harms (health anxiety, delayed diagnosis, low-grade wrong self-treatment) that probably matter most in aggregate. But it would establish a principle, which is that the cost of the products is not borne entirely by their victims.
The fifth is the division of responsibility. The current debate tends to collapse into a single question: who is to blame? But blame is not a useful frame, because the answer is genuinely distributed. Platforms that deploy chatbots into health-adjacent contexts (search engines, consumer-facing apps) carry a distinctive responsibility for the user experience and the framing of results. Model labs carry responsibility for training choices, safety mitigations and transparency about limits. Clinicians carry responsibility for talking to their patients about what these tools can and cannot do, and for building AI literacy into routine consultations. Regulators carry responsibility for closing the gap between medical device law and the general-purpose systems that are eating the medical advice market. Users carry the responsibility, one that no regulation can fully discharge, for remembering that a fluent sentence is not a diagnosis. Any credible accountability regime will allocate work across all of these actors rather than picking one.
The Case for Urgency
It is tempting, reading a long article about AI health misinformation, to conclude that this is another slow-motion technological harm, the sort that society will eventually absorb and metabolise. Regulators will catch up. Courts will muddle through. Model labs will bolt on safety features. And, in time, the general level of harm will reach some equilibrium that we will, reluctantly, accept.
The bixonimania result is an argument against this sanguine view. Not because fabricated diseases pose a widespread threat, they do not, nobody is actually being treated for bixonimania, but because they reveal something about the underlying system that would be almost impossible to see with real conditions. Real diseases exist in the training data. When a chatbot describes pancreatic cancer, its output is anchored, however loosely, to real clinical literature. Errors in that output are errors of degree: bad nuance, missing context, outdated guidance. They can be hard to detect precisely because the bulk of the surrounding material is correct. The bixonimania experiment strips that camouflage away. It shows the system behaving exactly the same way for a fabricated input as it does for a real one. The machinery has no internal test for reality. It never did.
If we had to summarise the cumulative message of the Mount Sinai studies, the Mass General Brigham sycophancy work, the Guardian's Overviews investigation, the New York Times' reporting on MEDVi, the Pew and KFF surveys, and Osmanovic Thunström's bixonimania experiment, it would be this: the public has been quietly migrating its health information practice to systems that were not designed for medical safety, that cannot reliably distinguish real from fabricated claims, and that are governed by no meaningful regulatory regime. This migration is happening faster than our institutional reflexes can track. And the harms it produces are not, for the most part, dramatic set-piece cases of the bromism kind. They are low-grade, distributed, and therefore hard to mobilise a political response around.
Which is why the bixonimania finding matters. It is, in a small and carefully engineered way, a dramatic set-piece. It gives us a clean story, a memorable name, and a graspable moral. The doctor that will not say “I don't know” has been handed a stethoscope by a third of the adult population. If that sentence does not alarm you, read it again. If it does, the question is what you, the platforms, the regulators, the clinicians and the labs are going to do about it.
A Last Word on the Word “Mania”
There is a small detail in the bixonimania story that deserves a coda. The name itself was a joke, and a pointed one. Mania is the psychiatric term for elevated, disinhibited mental states, often accompanied by overconfidence and a reduced grasp on reality. An eye condition cannot have mania. But a system can.
The deep worry about large language models in health is not that they occasionally get things wrong. Every source of medical information gets things wrong occasionally, including human doctors. The worry is that the system's confidence is disconnected from its competence, that its fluency obscures its unreliability, and that the scale at which it operates makes even small rates of error into population-level problems. That is not a hallucination in the ordinary sense. It is, to borrow Osmanovic Thunström's quietly devastating framing, a mania. A machine in the grip of its own eloquence.
Accountability, then, is not only a regulatory question. It is a cultural one. It requires us to recalibrate the authority we grant to fluent machines, and to resist the pleasing fiction that a well-formed sentence is the same thing as a true one. That recalibration will not happen spontaneously. It will have to be built, through regulation, through litigation, through research, through design, and through the ordinary discipline of public attention.
Bixonimania is not a real disease. The machine said it was. A great many people believed the machine. That is the story. The rest is what we decide to do about it.
