This is a tautology: the thing that can be validated can be validated.
I wonder if having AI models available would make it significantly easier to identify material created by that model. Seems it would be easier, but it would still be a big problem. Nets can be trained to identify ai vs not ai on a given model. And that's without needing access to the model weights, just training examples. But when there are N potential models...
Edit: Second paragraph added later.
I think you and I are basically in alignment... what this tells me is that 14% of real abstracts are so bad that other human beings call their BS. Meanwhile, this AI stuff is kinda working 32% of the time in generating legitimately interesting ideas.
So at that point - yeah, that sounds about right. The 32% is still so low that it shows AI is not anywhere near maturity, whereas 14% of human-generated is crap.
And, yeah - a short blurb like an abstract seems to be exactly the kind of text that ChatGPT is conditioned to do well generating. As others below note - once a human starts reading the rest, the alarm bells trigger.
I don't know that interesting has anything to do with whether people found them plausible.
The bar is not "this is legitimately interesting," it's "I've seen real abstracts worse than this."
This works very well to more or less stay on top of things with today's frantic publication pace in many disciplines.
Isn't the headline actually "Abstracts written by ChatGPT fool scientists 1/3 of the time"? Having never written one myself, wouldn't the abstract be the place where ChatGPT shines, being able to write unsubstantiated information confidently? I imagine getting into the meat of the paper would quickly reveal issues.
