> found instances of plagiarism on 20% of its pages, Guémart says, with fragments copied from intellectuals including author Albert Camus, physicist Louis de Broglie, and even some members of his thesis committee.Plagiarizing from people on your own thesis committee is a wild move.
I can't read enough French to understand every detail, but the plagiarism report shows that he was rephrasing all of the sentences rather than copying verbatim: https://v42.arretsurimages.net/fichiers/documents/2024-08-02...
He wrote the thesis at a time when it was impossible to identify lightly rephrased statements across a wide body of works. Now we can dump all of these documents into an LLM and have similar sentences surfaced for human review very quickly.
At the same time, it's no longer necessary to pick sentences from other people's work and change the phrasing. You can take someone else's paper, feed it into an LLM, and tell it to rewrite it for you. Easier than ever before to launder text.

> Plagiarizing from people on your own thesis committee is a wild move.Fun fact: he's using this to prove he didn't do anything wrong, as in "see? the people on my thesis committee didn't care I copied their own work, why should anyone else?"
The truth is, people on "thesis committee" don't read thesis. Some do. The director usually does, if he has the time. But many don't; they glance at the intro and conclusion and call it a day.

He also uses this to say it's unfair to punish him now with tools that didn't exist when he did the crime, which I find quite rich. If you murdered someone before DNA testing was available, that doesn't exonerate you in any way.

The very few cases that result in sanctions are generally horrendously flagrant.With another professor I caught a flagrant case in a student thesis and we faced attacks from the university administration because the student had a stellar transcript (also not the positive signal some might think). Punishment was almost inexistent.
It's difficult for me to imagine what it would take to get a doctoral thesis revoked.

Different leadership.If some in your experience erred on the side of leniency, then it stands to reason that others might err just as egregiously in the opposite direction.
In fact, your anecdote suggests erring is the norm. We should thus expect punishments to be inappropriate in one direction or another. An appropriate punishment seems rather unlikely.

It seems like that should be the case yet when I listen to any same group of people over a period of time, I often find that those unfamiliar with a concept or solution on day 1 end up repeating it as if it was their own a few weeks later. When I was younger I tended to assume there was an element of intentional theft, but I'm not sure it's natural and a prerequisite to educational acquisition that people can categorize original origin of ideas that may have bounced around them for a long time before they understood their significance.by elefanto

Sure a common answer would be intentionally copying in the same sessions, less likely is intentionally copying via eidetic memory.. But how much of a spectrum could there be in the middle for memory that would result in repeating a "plagiarism" form months later, etc?People say how obvious the parlor trick is when they look at a small model LLMs. Well, I've seen the same parlor trick in students who get good grades but seem weak at thought from fundamentals. It seems quite possible to me that in some examples we are now going after them because the environment changed. At much earlier points we did actually value the people who could recite even if somewhat brokenly because we lacked random order recital tools.

You’re wrong; academia has never accepted plagiarism of this magnitude. Enforcement is never perfect, but a doctorate is not an undergrad repeating verbally, it is not thoughtless writing. It’s a doctorate thesis for crying out loud, it has to be novel!by philistine
6/17/2026 at 7:20:06 PM
Crediting the origin of the idea is the whole point of citing sources. Learning something from someone doesn't mean the idea is yours now. It means that when you repeat that idea, you should cite the original source of the idea.This is just how scholarship works. It's not needed in the kind of day to day most of us do, but when you're writing a thesis for a PhD, this stuff matters. You're making the argument that you're expanding the totality of human knowledge with your dissertation, and that requires strict source citing to separate your original scholarship from the sources that influenced it.

What are these tools? I often write about stuff on my blog and I know a lot of what I’m writing or thinking about are ideas someone else has come up with (and that I’ve read but not remembered or not read and come up with a poor version of) but bog standard LLM DeepResearch never picks up the things I want.I imagine any tool that’s good at plagiarism detection would also kill it at this kind of literature research.
An example of something where it worked like this is that I had some ideas around how tribes evolve and so on and wrote them as I could think of them and ChatGPT was able to find that Darwin’s Cathedral had a far better synthesis of various much more rigorous takes on the subject.

Having seen plagiarism first hand, sometimes it exceedingly blatant. Like copying from a PDF that was produced via LaTeX — since LaTeX hyphenates words to split them across lines, if you end up keep-ing the hyphenation in, the te-xt reads like this.by nsagent
6/17/2026 at 7:40:39 PM
I've seen way worse: a Word document submission that preserved the style and fonts of the sources the plagiarer stole from. As in, font "Calibri 14" only appeared in paragraphs nicked from a source entirely written in that font - and the adjoining paragraphs weren't even size 14!!!Sadly, this idiot won an award before I was able to see their work, so they had the confusion of receiving an award, and THEN being told they were being spanked for unacceptable behavior. Since they were too stupid to hide the most blatant clues, they had a hard time comprehending this duality.

Most PhD have a few papers before finishing the dissertation. Many times the dissertation is made of a few paper by the author glued together. The papers usually chain, so it's instead ofintroduction1 -> main1 -> conclussion1
introduction2 -> main2 -> conclussion2
introduction3 -> main3 -> conclussion3
the thesis is something like
long introduction -> easy example -> main1 -> main2 -> main3 -> main of preprint -> long conclussion

Thesis by publication is only one way, and not even the most common in many fields. I can't access the actual text of this thesis, but the abstract sounds more like a monograph and I don't see any author publications before the thesis that would lead me to think otherwise.by AlotOfReading

What gus_massa was describing doesn't sound like thesis by publication. TBP usually uses the papers verbatim with some added material to make them cohesive to the overall thesis argument.

For both me (physics) and my wife (history), in the American system, both at strong universities, most of our committee members read most of of our dissertations. For her, in a field where thesis by publication is not standard (your thesis is typically revised into your first book), her committee at the defense focused on questions and comments based on the committee's reading of the thesis more than on the actual defense presentation, which is apparently also normal in the field. In part, I expect that's because the thesis is expected to be built into something important post-PhD, and comments are seen as helpful in that process.For me, it wasn't quite so apparent at the defense, and I don't know that all members read the final thesis carefully, but most of them had already seen me publish or present most of the research previously, often multiple times. I also know that some (and not just my advisor) did read the final thesis very closely. My thesis was only partially thesis by publication, however, which may have influenced this; it does now have a fair number of citations in its own right, which is somewhat unusual for the theses in the field, and potentially seen as awkward (it means there's significant work in the thesis that I never published elsewhere).
As a caveat, the American system (before current crises) does feel like it can have a two-tier system of PhD students who are expected to remain in academia (we both were) and ones who are not, even at strong universities. Expectations, and attention given, can vary considerably. The American system also tends to have larger and more closely involved committees than, for example, the UK/Irish system.
However, for the form of plagiarism discussed here: if someone had sentences from papers I published years ago interspersed in their work, and they weren't particularly notable sentences, I'm not confident I would notice. Depending on citations and what the sentences were, I'm not even sure I'd mind much, for example, if they were essentially copying a model definition.

by complex_pi

It's very broken, and I'm not sure if it's possible to write everything original given that you're expected to repeat 2/3rds of past research to fill pages when you write your thesis. For a master thesis that was at least 100 pages. For a PhD nowadays each one of those is published as a book. At least it was like that in my engineering department.by rjzzleep
6/17/2026 at 7:22:50 PM
It's a philosophy thesis, and unlike STEM or soft sciences (history, linguistics...), they are very light on fact which make them very dry. The will read the introduction, conclusion (which can have more words than a physic thesis), the main thesis that interest them the most, and count on their collegue to read the other main thesis.Also, very dry, so it's easy to loose focus, and you can read a rephrasing of your own thesis as a "he has the same ideas" (also, if you do that, please reference the author?)
I find a few of the example damning (hje should totally have added a citation and build his argument around it). Most less so, and i understand that a reader could not catch them.

Early work in any trade is mostly junk, and academia no exception.But the process of creating that work, engaged throughought that process with those purported to be more practiced, is usually pretty good at seeding enough expertise and confidence that you might be able to proceed more independently and with real novelty, or might at least be prepared to share the trade with others new to it.
That's the point of those years, and so it's more than a little ironic that AI is being used to undermine a practicing expert while simultaneously eroding the traditional process for becoming one by making it so easy to just generate slop and engage with hallucinations than to actually practice writing deep work or engaging with primary sources.

The whole idea of a PhD is acknowledging that a person has made a meaningful contribution.It is not "early work" but the end of early work. The masterpiece: the piece of work that proves a subject has mastered their craft.
If you're still producing junk you haven't earned your PhD.
by colechristensen
6/17/2026 at 5:53:56 PM
I guess I disagree with both of you.You probably have plenty of novel ideas in early career, but you almost certainly lack the experience and the basic understanding of your field to develop them properly. Most people have exhausted their own ideas by mid-career. But that that point, they should have the skills and the experience to work on the ideas they come across.
(Looking back at my PhD, it's quite amusing how little did I understand. On the other hand, many of the choices I intuitively made turned out to have some value. But in some cases, understanding that properly took a decade of work by other people.)
Your PhD work is an apprenticeship, after which you are expected to work as a journeyman. The masterpiece that qualifies you for independent work as a tenured professor is often called habilitation. Many academic cultures don't have those, because the expectations are so situational that they don't want to formalize them.

I believe the person was saying that in academia, literally everyone has a PhD, by definition since it's a requirement for the job, so the simple act of having it means nothing in the context of all of the other people that have it. It of course means a great deal since it's what let's you in to the room in the first place. Imagine interviewing 50 people, every single one of whom have an internship on their resume. What they did during their internship matters of course, but the simple act of having had one doesn't differentiate (matter).I find it rich how fast you are to jump to destroying the entirety of academia in one stroke. It's quite easy to say things we don't understand should not exist, of course I'm guilty of this myself from time to time. Have you done education beyond the bachelor's degree? It's a very different world.

Who does or doesn't have a PhD isn't terribly important in the scheme of things.

That's how it was maybe 100 years ago. Now PhD is just another bit of school work. Sometimes people manage to do really great PhD work, but most of the time it's pretty mediocre or straight garbage.In some ways, people doing research now have it way more difficult than people of the past. They have hundreds of years worth of research to study before they are on top of things and making an original contribution that stands out among the huge amount of research that already exists is really hard. If we want to keep PhD as a proof of meaningful work, then we ought to lengthen the graduate studies considerably. How about a 10 year PhD program, at the end of which you can really say you have mastered the field?

For example, there are some branches of linguistics where the big, important new monographs that move the field forward are often PhD theses (though typically the defended diss manuscript will get some very light rewriting and polishing before it appears from a publisher). After that, a scholar's publications over his/her career might be less ambitious and focused more on minutiae.

Personally I think writing with an LLM is at least as bad as stitching together phrases from others.The article doesn’t really expand upon what having fragments copied from others means. Even if it fits the letter of the definition, on a phd thesis that may or may not be a big deal. If he’s passing off the ideas of others as his, or faking his research by using the results of others or making them up, then that’s really bad. If he’s just using phrases / wording from others to get his original points across, it looks bad but I don’t see it as a huge deal, especially 30 years out from the phd.
A PhD is supposed to be original research, if the originality or integrity is in question that’s one thing, the rest is much more pedantic, even if technically wrong.

Is it confirmed, that it was intentional?That is his defence:
"Having read many books throughout his career, he may have “assimilated” them and “not always consciously” used them in his own writing, he said."
I have never published anything in academic context, but I did write a lot and I often found that phrases of the same topic I read before creep into my own writing, so I could see this happening to me without intention.
"the plagiarism report shows that he was rephrasing all of the sentences rather than copying verbatim"
On the other hand, this is in fact the standard defence when someone is accused of plagiarism. But sometimes it might actually be correct? (No idea here, my french ain't good enough either)
In general the reaction seems out of proportion to me, I much rather would like to have focus on actual fraud in science.
I sometimes read this blog for example and there seem to be other things going on with less attention.

At one point some things become more or less common sense or public domain. I think this would be rather than plagiarism "citation misbehavior" -- i.e. failing to cite or mention previous work. Like, not every math geometry paper needs to cite Euclid, you can just talk about triangles; or even copying passages from say the parallel postulate or whatnot, when actually delivering something novel, should not count as fraud or plagiarism, simply failing to cite a historical source, in my opinion.Also, I believe citation is usually limited to prior written work. I don't think citing personal communications is mandatory, but at least for me lots of ideas come up in personal communications, random discussions, etc.. I think actually we should give more credit in this case, but it shows that attributing fraud for failing to cite may be a little too harsh. Again, I don't know if that's the case here, or if his thesis is just some pastiche or prior work without any significant or original contribution.

Hopefully someone will eventually run plagiarism detection tools on every single doctoral and master's degree thesis ever submitted at every university worldwide. We need to make an example of those who committed academic fraud by ruining their careers.by nradov

TBH this sounds harder to parse than I expected as there are various situations where rephrasing things is acceptable. I think historically allusion and rephrase, particularly of common and well known things, without citation I think was much more common, but now academics often err in the direction of finding citations for the sky being blue or water wet. And I do trust that it very much went beyond the pale given the university revoking a degree.by Glyptodon

We must be very clear that this is very light rephrasing.Just to put it side-by-side in a form that will absolutely not work on mobile but might work if you're on desktop, here's a "two-column form" of an example plagiarism from the thesis:

It's worth pointing out that his M.O. was apparently to sometimes tweak the beginning of a sentence and then word-for-word copy some chunk from this source, some from that source, maybe tweak the ending to create a lead-in to the following sentence... but this is not just "oh some figures of speech lodged in my subconscious" -- this is like "whole sentences were mashed up together."Just some Google Translate of some of the plagiarized paragraphs, the thesis "The Unity of Physics" has:
> The idea that the diversity of reality is underpinned by a deeper unity is as old as thought itself. Great mythologies recount it, early philosophers affirm it, and modern science has taken up the same agenda by first unifying concepts of motion, matter, and space. Indeed, the desire for intelligibility can arguably not do without the idea of the One. However, simply attributing such a tendency to human nature does not validate its realizations. The proclaimed unity may well prove false—stemming merely from incantation, decree, or fantasy—while exerting a purely dogmatic fascination. Yet, if thought were to discover—amidst the shifting mirrors of phenomena—eternal relationships capable of encapsulating them, one could certainly speak of a joy of the mind. While not necessarily an essential framework of thought, the desire for unity corresponds to a nostalgia, a craving for the absolute, an ontological impatience. Yet, the moment it is expressed, it clashes with the irreducible dispersion of things. From this arises a rift between the desiring mind and the disappointing world. At the close of the century, the increasingly assertive power of physical theories—with their all-encompassing nature and unifying aim—prompts us to examine the foundations of the physicists' quest for unity, to define its limits, and to consider its current prospects.
This is claimed to be a mashup of paragraphs from three different sources, first, the sentence starting "However..." is said to hail from Jean-Michel Besnier's "Theories of Knowledge",
> Could the "monist" tendency inherent in the act of knowing be suggested any more clearly? Yet, simply positing such a tendency within human nature is obviously not enough to validate its realizations. Indeed, that unity may well prove illusory, stemming from sheer fantasy while exerting a purely dogmatic fascination. That is precisely why critical philosophy sets out to distinguish between the scientific and...
Followed by a bit of Camus' "Myth of Sisyphus,"
> If man were to recognize that the universe, too, can love and suffer, he would be reconciled. If thought were to discover, within the shifting mirrors of phenomena, eternal relationships capable of summarizing them—and of summarizing themselves in a single principle—one could speak of a happiness of the spirit of which the myth of the blessed would be but a ludicrous counterfeit. This longing for unity, this craving for the absolute, illustrates the essential movement of the human drama. Yet the fact that this longing exists does not imply that it must be immediately appeased.
The last sentence of Sisyphus was changed except for the "Yet" to what appeared to be an original sentence or two in the thesis, "Yet ... irreducible dispersion of things. From this arises a rift between the desiring mind and the disappointing world" -- but only to immediately jump into a third line from Parrochia's "Grand Revolutions of the 20th Century,"
> The increasingly assertive power of modern physical theories—along with their all-encompassing nature and unifying aim—now enables the scientist to occupy, to some extent, the role held by the philosopher from antiquity through the classical age. This is by no means the least significant consequence of the revolution we have experienced...
My very very initial read of this style, I would almost guess that he paid someone else -- someone who did not have a science education -- to write his thesis for him. And probably if that were true, then he had to provide the sources, "I like this sentence from here, that one from there, you see I highlighted this paragraph of this paper -- I'll highlight and you just paste everything together into one big whole and I'll look through the word processor and tweak a couple of sentence beginnings and endings to make everything look nice for the committee and probably only one person on the committee really reads a bit of it but let's be honest that they're all busy with their own research." With that sort of origin, that's how you get the "blind copying without rephrasing" type of thing (The person who's copying doesn't trust their technical chops to rephrase anything! "What if I choose the wrong word and it has another meaning in science and I embarrass myself?" -- so they go verbatim, "this made sense to someone who was well educated in the sciences, it can't be too embarrassing") with a little bit of tweaks between the chunks.
The really incredible thing about the plagiarism report is the 16 copié-collé/copy-paste sections AFTER this one, where it's just like "Yep, he stole whole pages at a time from his sources in just this way."
