Turnitin, but for the AI Era

The internet plagiarism crisis was curbed with technology. AI cheating may require a far more aggressive technological solution.

For the past couple of weeks, as students have submitted their final papers and faculty have immersed themselves in grading, academics on social media have been focused almost exclusively on a single topic: artificial intelligence (AI) cheating.

The problem is serious enough that Princeton University has just turned its back on 133 years of tradition. Since 1893, faculty members have left the room during exams, trusting students to behave honorably. No more. The university has now announced that proctors will be present during exams to prevent students from using their phones to cheat with AI.

Some might bristle at the word “cheating,” but let’s be clear: when students submit work that is not their own, that is cheating, plain and simple. There may be some gray area if the professor is allowing or even encouraging AI use, although, to my mind, that simply makes the faculty member complicit. But most professors, at least in the humanities, do not allow students to write with AI, much less encourage it. Professors are doing their best to discourage it and, in many cases, actively prohibiting it—except, perhaps, for certain very narrow applications such as research.

That’s why humanities faculty’s social media posts have been mostly bemoaning the fact that nearly all their students use AI on their written assignments. They know it, but can’t exactly prove it in a way that would stand up in a disciplinary hearing, much less in court, and it’s more than their career is worth to level allegations that might get them sued or even fired. And yet they’re incredibly frustrated because their students aren’t learning the things they need to learn in humanities classes—specifically, how to think and how to write.

As Massachusetts Institute of Technology writing professor Micah Nathan put it in a recent essay for the Guardian:

Writing isn’t just the production of sentences – it’s the training of endurance by way of sustained attention. It’s a way of learning what one thinks by attempting to say it. An LLM can reproduce the appearance of that activity, but it can’t replace it, because the value lies not only in the object produced but in the transformation that occurs during its making.

Or, in the words of Ralph Waldo Emerson, nearly 200 years before LLMs were even a thing, “Hence arises a grave mischief. The sacredness which attaches to the act of creation, the act of thought, is instantly transferred to the record.” For students taking humanities courses, the point is not the piece of writing; it’s the writing itself.

Humanities professors know this. They know their students are missing out on whatever small chance they once had in the modern corporate university to engage in deep thought, to struggle with putting those thoughts into words—activities indispensable to intellectual growth. And yet they feel powerless to do anything about it. Some, in a last-ditch attempt to stem the tide of AI non-writing, are going old-school, requiring students to write essays by hand in class. But this creates an extra burden for instructors, and it doesn’t work in every situation. Some classes are too big or configured such that in-class writing is nearly impossible. Moreover, it doesn’t take into account the fact that learning to write well involves working through a series of drafts, which cannot be done in a 75-minute class period.

Of particular concern are asynchronous online classes, where there is literally no practical way to proctor students’ writing without creating hours of additional work for instructors while remaining, at best, only marginally effective. For instance, instructors could require students to record themselves while writing. We could also require students to write their papers in person at campus testing centers, but that would defeat the purpose of offering asynchronous online courses, especially when many students do not even live within the institution’s service area.

I propose a technological solution to this moral problem. Sure, a moral solution would be better. It would be nice if we could educate students about the ethics of unauthorized AI use and shame them into doing the right thing. But we all know that isn’t going to happen. It did not stop internet plagiarism a generation ago. What did work, though, was a technological tool—Turnitin and similar sites. Once professors started using Turnitin, instances of students simply taking material from the internet and trying to pass it off as their own declined dramatically.

Just as AI is far more sophisticated than the internet, so must a technological tool to discourage AI cheating be more sophisticated than Turnitin. It can’t just be another type of detector, because “AI detectors” are notoriously unreliable. Texts as diverse as passages from the Bible and the Declaration of Independence have been flagged by various “detectors” as being substantially AI-generated. (Note that the sentence I quoted from Micah Nathan, above, would almost certainly be flagged as well, due to his use of the em-dash and the “it’s not A, it’s B” construction.)

What we need is something that goes far beyond a detector. We need a preventer. I’m no technologist, but I will try to explain in rough terms what I think might work.

Suppose every university required students to use some sort of software whenever they interacted with the institution’s learning platform—software that would prevent them from accessing AI at the same time. Or perhaps students could log into something similar to a VPN before connecting. Either way, they would not be able to use the learning platform without first accessing this tool, whatever form it might take, and the tool itself would prevent them from visiting AI sites while using it. It would also include a built-in word processor that would not allow cutting and pasting from outside sources, and students would be required to complete all their writing, including rough drafts, through this tool. (This might work for short-answer exams as well.)

One objection I heard when I ran this idea by a colleague was that students would just use AI to write their papers on another computer, then manually copy it into the learning-platform tool I’m proposing. To that I say: maybe. But if they could not simply copy and paste, and instead had to transpose the whole thing sentence by sentence, at least they would be doing some writing and probably learning something. Whereas now, by simply prompting AI to write their paper for them and then uploading it, they are learning nothing.

But perhaps there’s a way to eliminate that shortcut, too, as well as any other workarounds bright—if morally bankrupt—students might invent. I have no doubt brighter minds than mine could come up with solutions to all these problems within this very rough framework.

The bigger question is this: Can the human mind create a problem that the human mind cannot ultimately solve? I don’t believe so. Even in the humanities, we have our technologists. It’s time for them to put their big brains to work on the problem of AI cheating, so the rest of us can get back to the business of teaching thinking and writing.

    Or perhaps students would say “Bleep It” and drop the course, WHICH IS EXACTLY WHAT I WOULD DO.

    Which is what I would do now — when I was 19, the professor would probably also be told that he/she/it was a jackbooted Nazi thug more interested in personal power trips than actually teaching anyone anything, and while the courses I teach are state-mandated curriculum courses related to licensure exams, I’d politely say something similar to anyone suggesting this, adding one other thing — foolishness like this could well end the studies of the humanities.

    I’m reminded of the issues that Martin Luther had with indulgences circa 1517. Without going too deeply into the weeds, Pope Leo X needed money to rebuild Saint Peter‘s Basilica. What he did was offer forgiveness not based on repentance, but upon payment to the church. One could literally go out and commit any number of sins and then receive divine forgiveness for merely making a donation to the church. Depending on which version you listen to, one could even purchase indulgences for sins not yet committed — essentially purchasing a license to go commit sins.

    This led to both the Protestant Reformation and reforms in the Catholic Church itself, but Luther‘s big point was that forgiveness for sins was supposed to involve repentance, i.e. being sorry that one had committed them, and not a commerce in forgiveness. And most Protestant churches do not have confession in the Catholic model, there is no clerical forgiveness — people have to seek it on their own.

    I’m gonna make a bold leap here and say we should outright abolished grades, or at least the recording of grades. Yes, students should be told that they could do better or that they have done exceptionally well, but that should be between the student and the instructor — the class itself should be pass/fail.

    This is the way it was a century ago, in a time before microfiche, photocopiers, and web browsers. I am reminded of one graduation speech, where the college president congratulated all of the graduates, adding that “only the registrar knows how close some of you came to not graduating.”

    That’s how it was back then — in the 19th century, the registrar would write out the diploma. Various officials would hand sign it, and that was the only evidence that future employers would get that the individual had graduated from that college. And it worked. And this was before college had become vocationalized the way it is today — back then, most public college students were either training to become teachers or learning things they would use on the family farm.

    And I’m gonna get called names for this, but the husbands who married the graduates of the seven sisters never saw their transcripts and unless it had come up in conversation, had no idea what courses they had taken. No, they were evaluated on that basis of being able to carry on polite, intelligent conversations, their knowledge of manners, and the ability to be the business executive’s wife.

    It isn’t a case of her getting an A- or B+ in Baroque Music as much as her being able to carry on a conversation about it — and if she developed a personal interest in it, being able to share it with her family and friends, possibly even her church. As Alan Bloom wrote nearly 40 years ago, we have about four years to share Western culture with undergraduates — and I add that we are preparing them for a lifetime, long after they’ve forgotten what grade they received.

    Harvard’s Harvey Mansfield assigns his students two grades, the one which he believes they earned, and an official grade, so they don’t ruin their GPA by taking his classes. This is a risk that already exists — the only reason students take DEI courses is that they are guaranteed As if you recite back the required mantras.

    The student today takes a humanity course balancing an interest in the humanity against the risk of a lower grade and vocational failure. About half DEI classes would evaporate overnight if there was not this advantage in grading. If both DEI classes and the classes on Ancient Greece were past/fail, and if the classics department did a scintilla of advertising, my guess is the students would shift over to the latter.

    Hence, why not get rid of grades?

    Once students are no longer able to advantage themselves relative to other students by cheating, as they now are, the only people they will be cheating will be themselves.

  2. And nobody comments on the fact that richer and more technically savvy kids with two monitors, VPNs, funds to pay for the top essay-writing tools etc are the big “winners” in the Race to Cheat.
