> 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.

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.

A lot of "plagiarism" is not plagiarism. Feed stuff you wrote into those tools and it will call you a plagiarist every day because you wrote something similar to the person you learned it from.
I don't know about this case, but a lot of these kinds of cases truly are witch-hunts. It's not at all like the reproducibility crisis and faked data and images.

Academia is very broken if even your thesis committee is A) not interested in reading your thesis and B) can't even be bothered to when it is ostensibly their job.
What exactly is the point of dedicating years of your life to create something exactly nobody is going to read?

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.

They link to the document that shows the plagiarized sections side by side with their sources

I don't read enough French (especially at PhD thesis level!) to parse everything, but even I can see phrasings copied from the source documents in a lot of the examples. Some of them weren't even paraphrasing, they were lifting the exact distinctive word choices.

Rephrasing is worse than literal copying from a procedural point of view because it demonstrates intent and obviates a defense of mere incompetence.

No no he was copy pasting! In the Arret sur image article you can read a whole sentences plagiarized where the author just changed "En effet" to "Toutefois" (for example) at the begining of the quote.

I don't understand who would plagiarize for their PhD thesis. In a PhD thesis one of the main things you want is to "blame it" on others so that you don't have to "justify" the text. The more references you have, the better, and the less questioning you have (those are peer reviewed published references after all).

I can't read French, but having evaluated many of these plagiarism cases in the past, a lot of them truly are witch hunts.
The plagiarism will be something like "Einstein presented a new theory: ___" and the ___ and several sections of the next few pages will be barely modified Einstein quotes.
Should they have used quotation marks? Technically, yes. But using them breaks up the flow for the reader, and it's not like they are failing to give credit to Einstein.
As an academic, I really would not care much if someone did this to my work so long as they mention and cite me generally.

We need like an international plagiarism body to give you a stamp of approval when you write your dissertation so this doesn’t come back to bite you 20 years later.
A lot of times when I read certain plagiarism examples (Claudine Gay for instance)
Like plagiarism seems like it can happen for three reasons:
1. You intentionally tried to take someone else’s effort / ideas and make them your own. Real bad
2. You were lazy didn’t read enough to know to attribute correctly. Not great?
3. You were writing about a set of ideas that only have so many ways to express them. You really didn’t know.
I’m not saying we should give plagiarism a pass but maybe a statute of limitations? It seems really hard to tell 20 years later. Because to a certain extent - is this a case of 1? Did he pass of effort as his own? Or, if he has attributed Camus would you say “fair ‘nough mate, wasn’t central to your innovation”

Given the advent of LLMs, I don't know if plagiarism is ever a thing anymore. Nobody is stupid enough to include verbatim unless citing those works. Feed into an LLM to get a paraphrased version conveying the same meaning.
It is worrisome that the scientific machinery as it stands needs an overhaul in LLM era.

Plagiarism was always a stupidity/laziness charge though. People too lazy to reword the thing they’re copying and too dumb to realize they’d get caught.
If anything, the charge has even more gravity now since now you were too lazy to use an LLM. Kinda like when you see bad English in an Amazon product listing and wonder if you even want to buy from a company who was too lazy to use a free LLM to fix up the copy.
If the ecosystem required copy and paste to discover copied ideas, then it was doomed long ago and it’s a good thing that the AI era finally forces real process change.

The university should suffer consequences as well since their thesis committee completely failed to do their job, especially those who didn't even notice they were the people whose work was being plagiarized. Since it's been demonstrated that you can successfully copy/paste your way to a PhD at this university this calls into question the validity of every other PhD obtained there.

Knowing the political ideas of some journalists from "Arrêt sur Images", I would like that they also criticize other people than someone named "Klein".

It reads like those nightmares where you need to pass final exams again.
I guess nowadays it is much simpler to correlate some text with prior work, more so with LLMs. It is like those doping cases where several years later we are able to detect a previously unknown sustance in an old sample.

The French since Derrida won't produce anything better than academic postmodernist nonsense slop but without needing the outputs from LLM degradation. OTOH, the VLC and FFMPEG/Qemu creators should be put first as the good examples on being a good French STEM people instead of the 99% of bullshitters at TF1 debating nonsense which IMHO they became largely irrelevant since Francis Bacon and Pascal. These kind of people are just deluded manchilds which can't accept how the universe works at all. They thing everything orbits about them and that's the recipe for disasters such as Sokal.

Ironic especially given he spent the last 6 years going on all french public debate spaces to uniquely talk about "ultracrépidarianisme" / Dunning–Kruger effect and tell everyone they should listen to the real Scientists (like him, of course) and not the people-not-approved-by-media-and-state

The French can be profoundly petty. This smells like an act of personal / political revenge. Klein has a long standing as one of France's best-known scientists and a gifted popularizer of science. If a crime was committed then it is clearly his thesis committee that should be punished.
Shall we now impute dishonor on all those whose past writing cannot pass an AI examination? Do we start with Isaac Asimov, Carl Sagan, George Gamow, Michio Kaku, ...?
In any case, we need to hurry. You may not care, but there is some jackass in France who is losing sleep.

God damn¹, Louis XIV’s country that inspired La société du spectacle to Guy Debord is actually a great place to make a career as a courtesan, who would have guess.
Guillotine images in streets are also on the rise: I can no longer make the smallest road trip without seeing some plastered all around.
Looks like neither the wanna shine as elite in the bonnes gens side nor the drive me to unsustainable pauperized state in the crowd can refrain from their extreme propensities.

As much as ~60-70% of current academia leaders have bogus credentials and engage in plagiarism (from their colleagues, students, etc...).
It's just terrible, we live in a modern dark ages because of this.

Literally, but of course when there is a news about it, suddenly it's "surprising", it's like when people find out about the Olympic games that their favorite athlete is leveraging steroids, hormones, drugs and so-on and act surprised (sure, even a 16-year old at the gym is using steroids but the one that is "at the top" doesn't? Absurdity), it's tiring to see, obviously virtually everyone is using PEDs there, the same way as virtually every student cheat to an extent.
Cheating in life isn't necessarily that bad, if you are at the end of your studies and it's either you pass by cheating, either you don't, then the only logical thing to do is to cheat, who would go in more debt and potentially ruin their live doing otherwise, and WHY?

I don't know whether his popular science work is plagiarized or not but about his thesis, it seems somewhat stupid To punish him
So many things in physics have to be written in a very specific manner , to convey the meaning of the precise concepts being used. in such cases, it is a very common practice to copy the sentences used before, in order to ensure that everyone understands the meaning in a precise manner.
So then to call it plagiarism doesn't make any sense

He doesn't have a PhD in physics but in philosophy of Sciences. So he didn't plagiarize physics but philosophy.
