    > Our understanding is that only authors of papers appearing on arXiv can submit withdrawal requests. We have directed the author to submit such a request, but to date, the author has not done so.

    Between this and the subtle reference to “former second-year PhD student” it makes sense that they’d have to make a public statement.

    They do a good job of toeing the required line of privacy while also giving enough information to see what’s going on.

    I wonder if the author thought they could leave the paper up and ride it into a new position while telling a story about voluntarily choosing to leave MIT. They probably didn’t expect MIT to make a public statement about the paper and turn it into a far bigger news story than it would have been if the author quietly retracted it.

    • JohnKemeny 2 hours ago ago

      Seeing as how the author has signed in with an account whose email address is username@mit.edu, MIT could just take over the account.

      Edit: this comment was only partially serious, not meant as legal advice to MIT.

      • Aurornis 2 hours ago ago

        That's not how it works in the real world. That would be a fraudulent request and I suspect they'd invite legal trouble by impersonating someone else to access a computer system.

        Furthermore, if the author could demonstrate to arXiv that the request was fraudulent, the paper would be reinstated. The narrative would also switch to people being angry at MIT for impersonating a student to do something.

          I've done it for people who used my email to sign up for Facebook and Instagram. Presumably now they have a more rigorous verification flow but they used to let people use any email without checking. I can't have a potential criminal using a social account connected to me, so password reset and disable the account is the only rational solution. Obviously this is slightly more problematic for an institution.

          Emails are not people. You can impersonate a person, but you can't impersonate an email. If I own a company and I issue the email dick.less@privateequity.com but then have to fire him... using this email address to transfer company assets back to someone who can be responsible for them isn't fraud (for that purpose, at least). How is this not the same issue?

          • a2800276 an hour ago ago

            This would be a coherent argument if the paper was submitted by an email address. Instead the paper was submitted by a person. The email address serves to identify the person. Only the person can redact the paper.

          • IshKebab an hour ago ago

            If you misrepresent that you are dick.less then yes that would be fraud. They say only the authors can submit withdrawal requests, so you would have to present yourself as the author even though you aren't. That's fraud.

            Although not explicitly stated, i read previous comments as using dick.less@privateequity.com to cancel his personal Netflix account. (Let's say that privateequity.com allowed personal usage of company email.)

            I see a difference between accessing an email account and impersonating the previous account holder.

            Are you referring to an email address or an email message here?

      • kragen 2 hours ago ago

        That kind of thing might lead to arXiv not accepting any more papers from MIT, or at least any more takedowns.

  • elcritch 42 minutes ago ago

    In my opinion the paper shouldn’t be take down. Instead a note should be added noting the concerns with the pre-print and that’s it’s likely fraudulent.

    Edit: Since the paper has been cited, others may still need to reference the paper to determine if it materially affects a paper citing it. If the paper is removed it’s just a void.

  • intoamplitudes 6 hours ago ago

    First impressions:

    1. The data in most of the plots (see the appendix) look fake. Real life data does not look that clean.

    2. In May of 2022, 6 months before chatGPT put genAI in the spotlight, how does a second-year PhD student manage to convince a large materials lab firm to conduct an experiment with over 1,000 of its employees? What was the model used? It only says GANs+diffusion. Most of the technical details are just high-level general explanations of what these concepts are, nothing specific.

    "Following a short pilot program, the lab began a large-scale rollout of the model in May of 2022." Anyone who has worked at a large company knows -- this just does not happen.

    • btrettel 6 hours ago ago

      On point 2, the study being apparently impossible to conduct as described was also a problem for Michael LaCour. Seems like an underappreciated fraud-detection heuristic.

    • raphman 3 hours ago ago

      Oh, he also claimed that he got IRB approval from "MIT’s Committee on the Use of Humans as Experimental Subjects under ID E-5842. JEL Codes: O31, O32, O33, J24, L65." before conducting this research, i.e., at a time when he wasn't even a PhD student.

    • raphman 3 hours ago ago

      FWIW, in the q&a after a talk, he claims that it was a GNN (graph neural network), not a GAN.

      (In this q&a, the audience does not really question the validity of the research.)

        Oh interesting. I haven't talked to any recent graduates but I would expect an MIT PhD student to be more articulate and not say "like" every other word.

        There was a question at the end that made him a little uncomfortable:

        [1:00:20]

           Q: Did you use academic labs only or did you use private labs?
        
           A: (uncomfortable pause) Oh private, yeah, so like all corporate, yeah...
        
           Q: So, no academic labs?
        
           A: I think it's a good question (scratches head uncomfortably, seemingly trying to hide), what this would look like in an academic setting, cause like, ... the goals are driven by what product we're going make ... academia is all, like "we're looking around trying to create cool stuff"...

        Wayback of the Sloan School seminar page shows him doing one on February 24, 2025. I wonder how that went.

        I miss google search's Cache. As with the seminar, several other hits on MIT pages have been removed. I'm reminded of a PBS News Hour story, on free fusion energy from water in your basement (yes, really), which was memory holed shortly after. The next-ish night they seemed rather put out, protesting they had verified the story... with "a scientist".

        That cassyni talk link... I've seen a lot of MIT talks (a favorite mind candy), and though Sloan was underrepresented, that looked... more than a little odd. MIT Q&A norms are diverse, from the subtle question you won't appreciate if you haven't already spotted the fatal flaw, to leaving the speaker in tears. I wonder if there's a seminar tape.

    • 3s 2 hours ago ago

      I agree with point 1, at least superficially. But re: point 2, there are a lot of companies with close connections to MIT (and other big institutions like Stanford) that are interested in deploying cutting edge research experiments, especially if they already have established ties with the lab/PI

      Could a Benford's Law analysis apply here to detect that?

        How would you apply it, why would it be applicable?

    • constantcrying 5 hours ago ago

      A month by month record of scientists time spend on different tasks is on its face absurd. The proposed methodology, automatic textual analysis of scientists written records, giving you a year worth of a near constant time split pre AI is totally unbelievable.

      The data quality for that would need to be unimaginably high.

        To summarize, I have established three facts. First, AI substantially increases the average rate of materials discovery. Second,  it  disproportionately benefits researchers with high initial productivity. Third, this heterogeneity is driven almost entirely  by differences in judgment. To understand the mechanisms behind these results, I investigate the dynamics of human-AI collaboration in science.

        Not sure what you’re trying to say.

        • kccqzy 3 hours ago ago

          Maybe the point is that it is rare for a paper to have the pronoun "I" so many times. Usually the pronoun "we" is used even when there is a single author.

          • muhdeeb 2 hours ago ago

            Agreed! It’s pretty alien. I’ve seen brilliant single author work, but nothing that uses “I” unless it’s a blog post. The formal papers are always the singular “we”. Feels very communal that way!

            Nice to include the giants we stand on as implied coauthors.

            • kragen 2 hours ago ago

              Not being an academic, my (silent) reaction to singular "we" in academic writing is usually, "We? Do you have a mouse in your pocket? Or do you think you're royalty?" It's nice to hear of your more charitable interpretation.

              • mananaysiempre an hour ago ago

                There are, notably, two different if frequently confused “academic we” conventions, distinguished by their clusivity[1]: the inclusive “academic we” in constructions such as “thus we see that ...” refers to the author(s) and the reader (or the lecturer and the listener) collectively and is completely reasonable; the exclusive “academic we” referring only to the single author themselves, is indeed a somewhat stupid version of the “royal we” and is prohibited by some journals (though also required by others).

          • IshKebab an hour ago ago

            It's rare that "I" is used because usually papers have multiple authors, and also the academic community has a weird collective delusion that you have to use "we"... but there are still a reasonable number of papers that use "I".

          • pbhjpbhj 3 hours ago ago

  • tokai 3 hours ago ago

    Impressively the paper seems to have been cited 50 times already. I don't mind much if its taken down or not, but with the old guard publishers you can at least get a redaction notice or comment about the issues with a paper embedded in the publication. If you find this paper cited somewhere and follow it to the source at arxiv, you will never be made aware of the disputes surrounding the research. Preprint servers has somewhat of a weakness here.

    • forgotpwd16 an hour ago ago

      A weakness that goes hand-in-hand with the lack of peer review. There's moderation but shouldn't be considered equivalent to it. Trusting the study means trusting the author or reviewing the paper yourself. If a withdraw happens, either the author comments on why they did it[0] or, similarly to previous, you've to search it yourself.

      [0] E.g. arxiv/0812.0848: "This paper has been withdrawn by the author due to a crucial definition error of Triebel space".

    > The paper was championed by MIT economists Daron Acemoglu, who won the 2024 economics Nobel, and David Autor.

Unable to resolve those concerns, they brought it to the attention of MIT, which began conducting a review.

    So the PhD student might have been kicked out. But what about the people who "championed it". If they worked with the student, surely they might have figured out the mythical lab full of 1000s material scientists might not exist, it might exist but they never actually used any AI tool.

  • dougb5 2 hours ago ago

    This makes me think about the credibility of single-author vs. multi-author papers in different disciplines. In computer science, a paper is seen as suspicious if there's just one author (at least nowadays). But in economics it seems much more common. Can an economist explain this for me (or perhaps a paper written by multiple economists?)

          A study that cannot be replicated is a study that cannot be falsified. Authors don't mind putting their names on them because there's no accountability to be held and is purely net positive (one more publication and additional citations).

      I always wonder what happens with these high-profile transgressors. I once created a Google News alert for a high-level Apple employee who went to jail for some criminal act at Apple and never saw any indication of him again. I’m guessing his career in economics is likely over (he’d previously worked at the NY Fed before starting at MIT) and I wonder what he’ll end up doing—will he be able to find some sort of white-color work in the future or will he be condemned to retail or food-service employment.

      • Workaccount2 3 hours ago ago

        There are a gazillion small companies out there that hire white collar workers with only a rudimentary background check (are they a felon) and an interview that is more a vibe check than anything.

        He probably will never be someone of significance, but he also will probably be able to have a standard middle class life.

        • jgerrish 20 minutes ago ago

          But would you want to work for a company that just does a vibe check, or one that raises the bar with every hire?

          That high-level Apple employee was probably a manager and oversaw hiring people.

          I would tell myself every day, "I wouldn't hire me."

          It's not self-defeating.

          It's not being a victim.

          I wouldn't let it stop me from trying.

          It's being accurate about what kind of company you'd want to build yourself, and the internal state of a lot of hiring managers. And with a true model of the world you can make better decisions.

      • Aurornis 3 hours ago ago

        The MIT announcement says they asked him to retract the paper but he wouldn't, which led to them making the public statement about the paper.

        They may have thought they could jump into an industry job, including the paper and all of its good press coverage on their resume. Only the author can retract an arXiv paper, not their academic institution. It wouldn't be hard to come up with a story that they decided to leave the academic world and go into industry early.

        MIT coming out and calling for the paper's retraction certainly hampers that plan. They could leave it up and hope that some future employer is so enamored with their resume that nobody does a Google search about it, but eventually one of their coworkers is going to notice.

  • hooloovoo_zoo 3 hours ago ago

    I don't think arXiv should take it down even if it is fraud. ArXiv is more about being a permanent store than a quality judge.

    • forgotpwd16 an hour ago ago

      Actually arXiv is moderated and if policies are violated they may even withdraw* a paper themselves, if it wasn't declined to be published in first place. Regarding policies, it's mentioned that a "submission may be declined if the moderators determine it lacks originality, novelty, significance, and/or contains falsified, plagiarized content or serious misrepresentations of data, affiliation, or content."

      *Note that this creates a new version lacking any download which also becomes the default but any previous ones are still available.

      • hooloovoo_zoo 2 hours ago ago

        Judging quality/fraud is the role of a journal/conference, not arXiv. If a paper gets rejected does it come off arXiv? No. If a paper is never submitted does it come off? No. If a paper is retracted, does it come off? No. ArXiv should avoid making as many subjective determinations as possible.

        • andy99 2 hours ago ago

          I agree with this, it's actually a good reminder not to trust a preprint server. Arxiv already has an inappropriate air of validity, moderation will only make it worse.

          (Incidentally, I don't think misplaced trust in preprints is much of an academic issue, people that are experts in their field can easily judge quality for themselves. It's laypeople taking them at face value that's the problem.)

        >Earlier this year, the COD conducted a confidential internal review based upon allegations it received regarding certain aspects of this paper. While student privacy laws and MIT policy prohibit the disclosure of the outcome of this review, we are writing to inform you that MIT has no confidence in the provenance, reliability or validity of the data and has no confidence in the veracity of the research contained in the paper. Based upon this finding, we also believe that the inclusion of this paper in arXiv may violate arXiv’s Code of Conduct.

        It sounds like "we don't like it and won't tell you why, we're hiding behind MIT policy and vague notions of privacy".

        MIT should just demonstrate in a paper what the shortcomings are and print it, adding it to the citation tree of the original.

          FERPA is federal law. It is quite likely that MIT is legally bound to not release some pieces of evidence which are crucial in this case (hypothetically, for example: that the student's educational record is inconsistent with claims made in the paper).

        Perhaps replace "take down" with "withdraw" (arXiv's mechanism to deal with bad papers post-publication; what MIT calls for) or "retract" (the mechanism that traditional journals employ and similar to previous). In arXiv's way of handling papers, "removal" and "withdraw" are distinct[0] and, based on some comments in this thread, current title seems to create confusion that is about the former.
