For me it was the eyes. Pretty much all of the real faces had realistic reflections in the eyes. The AI ones didn’t.
I got 9/10.
Comment on Test Yourself: Which Faces Were Made by A.I.?

2/10. Are there any giveaways that a face is AI generated?

At least until AI image generators turn RTX on and do path tracing.

I know you're joking, but the opposite is likely the future of game graphics: First a conventional render, perhaps even with path-tracing (although that might not be necessary), then AI on top:

I’ve done a lot of stuff with generative models called GANs, like StyleGAN (2?) which I believe these pictures to be from. My main focus is the “hair bubble effect”. This works best for people with longer hair, which is why I had 30% wrong in this test. Basically, by starting at images generated by these models for a long time, I started noticing that it is bad at creating the few loose hairs that stand out from the main pack. These plucks of hair often seem to go around some invisible “bubble” or weirdly flow together with the background. So my main point of focus is often the transition between hair and background, or just the hair in general, since that’s where it’s most likely to mess up. But the images picked here were also intentionally picked to be the most confusing according to the rest of the article, so it’s not that weird that these are hard to classify. Some of the real ones looked extremely AI to me, and it was only after the first false positive that I got a lot more careful with labeling some as “AI” than I normally would.

2/10 here as well. I went fast to test myself.

You beat random chance! I mean in the opposite direction… So I’m not really sure what that says…

The eyes. Look for non-circular pupils or noticeably different-sized pupils.

I was mostly looking for details to indicate the person was real. Got 8/10. Someone had an odd tooth, someone else's eyebrow hair looked like they had just woken up. There was one picture I immediately knew was AI, because it just seemed off. Another had some strange wrinkle texture on the neck that just seemed unnatural. One of the 2 I got wrong because I thought the eye wrinkles were too much for the rest of the face. Turned out to be a real person.

I got 6/10. For me the thing I was looking for most was images that seemed to have wrinkles and things that seemed slightly blurred out. I don’t know if this is because it’s trained on a dataset where real people frequently do this (which is why it’s only a 6/10, because many pictures of real people have this feature as well), or if it’s because it’s generating detail and that’s just how it looks in current versions.

Faces are very well done these days, you can go to thispersondoesnotexist.com and keep refreshing images. Eventuall you’ll notice little things, like earrings not matching or sunglasses being 2 different halves melded together, hats and hair can look weird, etc
But most of them appear very human

That’s wild. Some of them are really good, but I see what you mean once you keep refreshing the page. Glasses are a good tell once you look closely. Earlobes also appear to be difficult to perfect as well.
I went back to the NYT article and tried again with my goldfish memory using that deduction and got 6/10.

Also, these are all emulating professional camera conditions. In a more standard phone photo scenario, the lower quality can lead to all sorts of weird looking illusions in real photos that can make them look weird. I was playing with some AI photo editing and saw some things that looked off which I thought was the generation messing up, but after checking the original photo again I saw that the weird stuff was actually in the original photo due to weird shadows or motion blur.
