  If the fake disease is in the medical textbooks, wouldn't doctors have diagnosed for it? For eg: Miasma theory and bloodletting were dominant, yet incorrect, medical doctrines used for centuries until the late 1800s. Miasma proposed that foul-smelling air from rotting matter caused diseases like cholera, while bloodletting (phlebotomy) was used to balance bodily humors.

  You’ve seen people game adsenseIt’s gunna be even wilder when people realise they have an incentive to seed fake information on the internet to game AI product recommendationsI’ve already bought stuff based off of an AI suggestion, I didn’t even consider it would be so easy to influence the suggestion. Just two research papers? Mad.

  It sounds like there wasn't really a counter narrative for the models to learn from. This feature of how llms accumulate information is already being gamed by seeding the internet with preferred narratives.I'm not sure how many Medium articles, blog posts and reddit threads I need to put out before grok starts telling everyone my widget is the best one ever made, but it's a lot cheaper than advertising.

  I'm not especially defending AI, but isn't this information like that one time a professor changed the content on Wikipedia to play a big 'gotcha' on his students?Instead of proving that Wikipedia is "bad", that professor didn't realize he proved that Wikipedia is working as intended: if you write something wrong in Wikipedia, over a certain period of time (yes, it can be long, I know), it will be corrected.About this article in Nature, if you feed AI incorrect information, it's gonna spit it back at you. When you think about it, when did we say that AI was self correcting?In a broader logic, imagine we teach kids something false, as an experiment of course. And then we wait a little bit, and we watch some years later how much of this people still repeat the false information they were taught. And then we'd write a paper to say "oh look at those people they're dumb", wouldn't that be a little unfair? even unscientific?

  At first I thought this was a Nature paper. Turns out, it's a feature article.The true test for this would be a blind test that involves human doctors - primary care since that's where something like this fits - exposed to the same data (fake papers), as well as LLMs.Isn't it interesting that the fake papers made it onto science preprint servers? I didn't think that they were open to posting by random authors and had some basic checks in place. Currently these papers are showing as "withdrawn" on their DOI links [1] [2].[1] https://doi.org/qzm4 [2] https://doi.org/qzm5

  I bet you could easily convince LLMs of Dihydrogen-Oxide toxicity.

  I wonder if one of the issues is, LLMs treat all data sources equally, or they don’t really weight the reputation properly (pure speculation, based only on seeing the results). I know that a large portion of code out there, is not written by seasoned experts, so rather naive code is the fodder for AI. It often gives me stuff that works great, but is rather “wordy,” or not very idiomatic.For example, court cases mentioned in fictional accounts. If they are treated as valid, then that could explain some of the hallucinations. I wonder if SCP messes up LLMs. Some of that stuff is quite realistic.I also suspect that this is a problem that will get solved.

  This is partly why this talk about AI "solving science" should be taken with a grain of salt. Here the authors intentionally poisoned the publication record, but there are millions of papers out there that are also garbage, and it would be very hard for either a human or a LLM to distinguish them from actual work.

  What stops a small, or even a large group of people to intentionally "poison" the LLMs for everyone? Seems to me that they are very fragile, and that an attack like that could cost AI companies a lot. How are they defending themselves from such attacks?

  This is a strong contender for an Ignobel.

  I think this problem is interesting and it carries over to the general public. Is the general public and are the media outlets also equally skeptical? Are they aware of the distinction between published journals vs preprints?Take this as an example:Search for this in google: "ai data centers heat island". Around 80 websites published articles based on a preprint which was largely shown to be completely wrong and misleading.https://edition.cnn.com/2026/03/30/climate/data-centers-are-...https://www.theregister.com/2026/04/01/ai_datacenter_heat_is...https://hackaday.com/2026/04/07/the-heat-island-effect-is-wa...https://dev.ua/en/news/shi-infrastruktura-pochala-hrity-mist...https://www.newscientist.com/article/2521256-ai-data-centres...https://fortune.com/2026/04/01/ai-data-centers-heat-island-h...You may not believe it but the impact this had on general population was huge. Lots of people took it as true and there seem to be no consequences.What should be a takeaway for the LLM should also be a takeaway for the media outlets.

  Seems to be a failure of the publishing system.For humans, or Ai, to have any knowledge, we need to have trustworthy sources.Naturally,when you use publishing systems considered trust worthy, that is going to be trusted.

  This would work on people too, you can see daily fake info/text/videos and many people believing in them.LLMs do not think, why this is still hard to understand? They just spit out whatever data they analyse and trained on.I feel this kind of articles is aimed at people who hate AI and just want to be conformable within their own bias.
• OutOfHere
  The authors of all recent bogus papers should be outed and fired. I hope a future AI can identify many of them.

  Bad. But scientists faked data and told people it wasn’t is ok?Nature had to recall quite some papers.I hope that we all keep the balance.

  This is exaggerated. Here's what happenedEdit: I don't think its exaggerated and I think its important .1. they invented a new disease and published a preprint (with some clues internally to imply that it was fake)2. asked the Agent what it thinks about this preprint3. it just assumed that it was true - what was it supposed to do? it was published in a credentialised way!It * DID NOT * recommend this disease to people who didn't mention this specific disease. Edit: I'm wrong here. It did pop up without promptingIt just committed the sin of assuming something is true when published.What is the recommendation here? Should the agent take everything published in a skeptical way? I would agree with it. But it comes with its own compute constraints. In general LLM's are trained to accept certain things as true with more probability because of credentialisation. Sometimes in edgecases it breaks - like this test.

  Well yes of course.In the old days of computing people liked to say “garbage in, garbage out”.

  Interestingly ChatGPT right now answered> Bixonimania is not a real disease. It was deliberately invented by scientists as an experiment to test whether AI systems and researchers would spread false medical information. Here’s the simple explanation ...

  One of the frustrating parts about LLMs is that they are so neutered and conditioned to be politically correct and non-offensive, they are polite more than correct.Its too easy to "lead the witness" if you say "could the problem be X?" It will do an unending amount of mental gymnastics to find a way that it could be X, often constructing elaborate rube Goldberg type logic rats nests so that it can say those magic words "you're absolutely right"I would pay a lot of money for a blunt, non-politeness conditioned LLM that I would happily use with the knowledge it might occasionally say something offensive if it meant I would get the plain, cold, hard truth, instead of something watered down, placating, nanny-state robotic sycophant, creating logical spider webs desperate for acceptance, so the public doesn't get their little feelings hurt or inadequacies shown.
