Earlier quoted context omitted.

The captcha should only appear once per quiz session. Do you have cookies blocked or a similar configuration? Visiting https://aiquiz.ronsor.com/session_dump.jsp will show you your session information.

"quizCompleted": 30,

You should be able to visit the quiz page directly and get your results: https://aiquiz.ronsor.com/quiz.jsp

If it asks for a CAPTCHA again, it should only do so once.

To be fair, to me, title should be more like are you able to tell cherry picked AI images from cherry picked human created images, since both clearly were selected to appear similarly picked to confuse a human in my opinion.

No idea if that’s accurate, or even if it is, how to fix it, but one idea would be to get a list of the top ten search queries on a popular stock image site, then randomly pick an AI image and human image; problem being that in my experience it would become painful obvious on average which was real and which was AI, which to me points out that AI images as they’re currently “generated” heavily depend on humans to create prompts and curate which are shared.

How did you filter, select, etc the images?

>> CAPTCHA: In order to prevent bogus quiz submissions and reduce required network resources, please solve the following problem: (add/subtract two number) >> Repeated CAPTCHA prompts, image, repeated CAPTCHA prompts, image, etc. Wow. No idea what is going on, but you managed to make the most unusual and annoying experience I have had on the web ever. Curious, what was your reasoning for doing this?

The CAPTCHA is supposed to filter bots. For some reason, the site has a bug keeping track of sessions (it just stops being able to), so as a result, it can't keep track of any quiz data. I restarted the server so it should be working again.

Thanks, fixed it, at least for me.

It keeps asking me to do arithmetic problems to prove I'm not an AI (several in a row) and then loses its place and starts over with #2 (not necessarily the same image).

I guess the real question isn't "Can you tell if an image is AI-generated?" but "Can the server can tell if guesses are AI-generated?"

Actually no, they were not cherry picked. Except for generations which did not match the prompt at all, I took every image that was created.

For the human images, I just took things from Unsplash's and ArtStation's front pages. I clicked on those images without looking.

Early next year I'll do a better quiz with more variety. This was a weekend project.

I was looking for tells, but things like landscapes or pictures where there's no hands or eyes tend not to have them as much.

Since it didn't tell you what ones you got right, I can't use my 76% as evidence (I got a lot of blurry pictures of forests, which are hard because it's either an AI or a low-effort background art asset), but while landscapes are the hardest, a bunch of obvious tells without hands or eyes (and the other well-known one: text) are:

Shoelaces. Or anything where things pass over and under other things. The AIs did really poorly with belt buckles too. Its sense of object permanence is entirely stochastic, and small details don't get a lot of virtual brain power devoted to them.

Straight lines and repeating patterns. "Human hand holding a 30cm ruler in front of a chain link fence" is probably AI kryptonite.

Symmetry. If there's a nontrivial object that's supposed to be symmetric, chances are, it won't be.

Swept curves and perspective. Another thing that's stochastic is the AI's understanding of how 3D spaces map onto 2D images.

Circular objects being transformed in 3D, like a roundabout being viewed in perspective, or a curved road moving off into the distance will typically be inconsistent with human expectations.

Of course, some of these mistakes are also made by human artists, but generally the human artists who make these mistakes also have amateurish colouring, lines or brushwork, and AIs are generally pretty good at emulating good brushwork.
