Llm detectors are always snake oil 100% of the time. Anyone claiming otherwise is lying for personal gain.

I just want to point out that there were text generators before ChatGPT, and they were ruining the internet for years.

Just like there are bots on social media, pushing a narrative, humans are being alienated from every aspect of modern society.

What is a society for, when you can't be a part of it?

Well if your books start talking back you should get help. The computer just started getting good (I remember Dr Sbaitso)

I'm the type to be in favor of new tech but this really is a downgrade after seeing it available for a few years. Midterms hit my classes this week and I'll be grading them next week. I'm already seeing people try to pass off GPT as their own, but the quality of answers has really dropped in the past year.

Just this last week, I was grading a quiz on persuasion and for fun, I have students pick an advertisement to analyze. You know, to personalize the experience, this was after the super bowl so we're swimming in examples. Can even be audio, like a podcast ad, or a fucking bus bench or literally anything else.

60% of them used the Nike Just Do It campaign, not even a specific commercial. I knew something was amiss, so I asked GPT what example it would probably use it asked. Sure enough, Nike Just Do It.

Why even cheat on that? The universe has a billion ad examples. You could even feed GPT one and have it analyze for you. It'd be wrong, cause you have to reference the book, but at least it'd not be at blatant.

I didn't unilaterally give them 0s but they usually got it wrong anyway so I didn't really have to. I did warn them that using that on the midterm in this way will likely get them in trouble though, as it is against the rules. I don't even care that much because again, it's usually worse quality anyway but I have to grade this stuff, I don't want suffer like a sci-fi magazine getting thousands of LLM submissions trying to win prizes.

As someone who has been a teenager. Cheating is easy, and class wasn't as fun as video games. Plus, what teenager understands the importance of an assignment? Of the skill it is supposed to make them practice?

That said, I unlearned to copy summaries when I heard I had to talk about the books I "read" as part of the final exams in high school. The examinor would ask very specific plot questions often not included in online summaries people posted... unless those summaries were too long to read. We had no other option but to take it seriously.

As long as there isn't something that GPT can't do the work for, they won't learn how to write/do the assignment.

Perhaps use GPT to fail assignments? If GPT comes up with the same subject and writing style/quality, subract points/give 0s.

Last November, I gave some volunteer drawing classes at a school. Since I had limited space, I had to pick and choose a small number of 9-10yo kids, and asked the students interested to do a drawing and answer "Why would you like to participate in the drawing classes?"

One of the kids used chatgpt or some other AI. One of the parts that gave it away was that, while everyone else wrote something like "I want because", he went on with "By participating, you can learn new things and make friends". I called him out in private and he tried to bullshit me, but it wasn't hard to make him contradict himself or admit to "using help". I then told him that it was blatantly obvious that he used AI to answer for him and what really annoyed me wasn't so much the fact he used it, but that he managed to write all of that without reading, and thought that I would be too dumb or lazy to bother reading or to notice any problems.

Did he get into the class after all that?

I have a similar background and no surprise, it's mostly a problem in my asynchronous class. The ones who have my in person lectures are much more engaged, since it is a fun topic and I don't enjoy teaching unless I'm also making them laugh. No dice with asynchronous.

And yeah, I'm also kinda doing that with my essay questions, requiring stuff you sorta can't just summarize. Important you critical thinking, even if you're not just trying to detect GPT.

I remember reading that GPT isn't really foolproof on verifying bad usage, and I am not willing to fail anyone over it unless I had to. False positives and all that. Hell, I just used GPT as a sounding board for a few new questions I'm writing, and it's advice wasn't bad. There's good ways to use it, just... you know, not so stupidly.

How did they estimate whether an LLM was used to write the text or not? Did they do it by hand, or using a detector?

Since detectors are notorious for picking up ESL writers, or professionally written text as AI-Generated.

They developed their own detector described in another paper. Basically, this reverse-engineers texts based on their vocabulary to provide an estimate on how much of them were ChatGPT.

They just asked a few people if they thought it was written by an LLM. /s

I mean, you can tell when something is written from ChatGPT, especially if the person isn't using it for editing, but is just asking it to write a complaint or request. It is likely they are only counting the most obvious, so the actual count is higher.

[–] [email protected] 11 points 2 weeks ago

I don't know of any reason that the proportion of ESL writers would have started trending up in 2022.

That’s scary shit. Hopefully this can slow down some.
