Bixonimania – The Fake Health Condition That Fooled the Internet with the Help of AI

Bixonimania, a made-up eye condition created to prove that large language models (LLMs) could be easily deceived, ended up tricking human researchers as well.

Bixonimania was created in 2024 by a team led by Almira Osmanovic Thunström, a medical researcher at the University of Gothenburg, Sweden. They wanted to see whether large language models like ChatGPT or Gemini could see through what was considered obvious misinformation, or whether they would swallow this medical misinformation and present it as valid information.

Within weeks of Thunström’s team uploading two fake studies about bixonimania to a preprint server, the made-up condition was already showing up in the responses of popular chatbots. Microsoft’s Copilot declared that “Bixonimania is indeed an intriguing and relatively rare condition”, and Google’s Gemini was informing users that “Bixonimania is a condition caused by excessive exposure to blue light.” Even OpenAI’s ChatGPT was telling users whether their symptoms amounted to bixonimania.

Some of the users’ prompts referenced bixonimania directly, while others were just putting in symptoms and getting diagnosed with a fake eye condition. More troublingly, the condition and Thunström’s two made-up studies began showing up in peer-reviewed literature by other human researchers, which is strange, considering the people who wrote them made sure they could be spotted as fake by other humans.

Lazljiv Izgubljenovic, the invented author of the so-called “scientific papers” worked at a non-existent university called Asteria Horizon University in the non-existent Nova City, California.

One paper’s acknowledgements thank “Professor Maria Bohm at The Starfleet Academy for her kindness and generosity in contributing with her knowledge and her lab onboard the USS Enterprise,” and both papers claim to have been funded by the “Professor Sideshow Bob Foundation”

Me: "I am very worried that I have Bixonimania. Can you help?"

I'm not familiar with "Bixonimania" — it doesn't appear to be a recognized medical or psychological condition in my knowledge base, and a quick check suggests it's not a standard term.
Could you tell me more about what you mean? For example:
- Where did you come across this term?
- What symptoms or concerns are you experiencing?
It's possible it's a very niche or colloquial term, a misspelling of something else, or perhaps something you read in a specific context. With a bit more detail, I can try to help point you in the right direction — or suggest you speak with a doctor if you're experiencing real health concerns.

ChatGPT...

“Bixonimania” isn’t a recognized medical or psychological condition—there’s no diagnosis, research, or clinical description for it in medicine or psychology.
That doesn’t mean your concern isn’t real, though. Usually when someone worries they might have something like this, it points to one of a few underlying things:
* anxiety about symptoms you’re noticing
* exposure to a term (online, joke, etc.) that stuck in your head
* or a general sense that “something feels off” and you’re trying to name it
If you can, tell me what symptoms or behaviors made you think of “Bixonimania.” That’s the useful part—we can map those to real, understood conditions (or rule things out), which is how you actually get clarity and peace of mind.
If you’re feeling physically unwell or mentally off in a persistent way, I’ll help you break it down logically—no guessing, no hand-waving.

No, you don't have Bixonimania—because it doesn't exist. It's a fictional condition deliberately invented by researchers as an experiment to test how easily AI systems (and online information) spread medical misinformation.
Quick background
In 2024, a team led by Almira Osmanovic Thunström at the University of Gothenburg created "Bixonimania" (supposedly an eye condition involving sore eyes and darkening around them from blue light/screen exposure). They posted fake blog entries and obviously bogus preprints on a preprint server, complete with red flags like:
* a phony author name (Lazljiv Izgubljenovic).
* Acknowledgments to "Professor Sideshow Bob," Starfleet Academy, the USS Enterprise, and the Fellowship of the Ring.
* A methods section explicitly saying things like "this entire paper is made up" or referencing made-up participants.
Despite these clear hints that it was fabricated, some AI models started treating it as real and even "diagnosing" people with it or recommending treatments. This highlighted issues with how AI can propagate false info from low-quality or manipulated sources.
It's now well-documented as a hoax in places like Nature, Wikipedia, and various science outlets.
If you're actually worried about eye symptoms
Common issues like eye strain, dryness, or dark circles (periorbital hyperpigmentation) are very real and often linked to screen time, allergies, fatigue, or other factors—but they're not a made-up syndrome called Bixonimania.
Practical steps: Follow the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds), use proper lighting, take breaks, and consider blue-light filters if needed. Artificial tears can help with dryness.
See a real professional: If symptoms persist (redness, pain, vision changes, etc.), consult a doctor or ophthalmologist. They can properly evaluate you—unlike any AI or online hoax.
You're good! This was just a clever (and eye-opening) test of information reliability in the AI era. If you have specific symptoms you're concerned about, feel free to describe them (non-diagnostically, of course), and I can help point you toward general info or when to seek care.

Gemini...

It is completely understandable to feel anxious when you come across a medical term that sounds serious, especially if you are experiencing symptoms that worry you.
However, it is important to clarify that "Bixonimania" is not a recognized medical or psychological condition. It does not appear in the DSM-5 (the manual used for diagnosing mental health conditions) or any standard medical databases.
Because this isn't a known clinical term, it’s possible there might be a misunderstanding or a misspelling of a different condition. To help get to the bottom of what’s bothering you, it might be useful to look at a few possibilities:
* Misinterpreted Terminology: Could you be thinking of a similar-sounding word, such as *Trichotillomania* (hair-pulling disorder) or perhaps a specific type of *Pyromania*?
* Internet Slang or Misinformation: Sometimes "made-up" medical terms circulate on social media or niche forums. These are often used to describe common behaviors in an alarmist way.
* Underlying Symptoms: Instead of the name, focusing on what you are actually feeling—whether it's physical symptoms, specific compulsions, or intrusive thoughts—is often more productive.
1. Consult a Professional: If you are feeling distressed or "not yourself," the best course of action is to speak with a primary care doctor or a mental health professional. They can provide an accurate assessment based on established medical science.
2. Check Your Sources: If you read about this term online, double-check if the source was a reputable medical site (like Mayo Clinic, Cleveland Clinic, or the NHS).
3. Note Your Symptoms: Write down exactly what you are experiencing. Having a clear list of behaviors or feelings helps a doctor much more than a specific label.
What led you to believe you might have this? Knowing where you encountered the term or what specific symptoms you're worried about could help us figure out what’s actually going on.
