How do you spot an ai generated face according to science?

AI faces are real people who look like they were painted by a robot that is still learning how eyes and hair should sit together.

When you ask if a face is AI-generated, science points to tiny "mistakes" in the details. Think of an AI picture like a digital painting where the artist forgets to clean up their tools before taking the photo. The main character looks perfect, but if you look closely at the edges or the background, things get weird.

Humans are mostly symmetrical, meaning your left eye matches your right eye very well. AI struggles with this. It might give you two eyes that are slightly different shapes, like a dog in a cartoon where one eye is bigger than the other. This happens because the AI builds the face piece by piece rather than all at once, so it sometimes loses track of exact matching.

Look at the hair and the background behind it. Real photos have clear lines where hair meets sky or wall. AI often blurs this line. It might make a hair strand disappear into the blue sky or turn an earbud wire into a weird snake. This is called artifacting. It looks like smudged paint on a canvas.

Look at the little white dots in the person’s pupils (the black center of the eye). These are reflections of lights in the room. A real photo shows these dots clearly and they match up. An AI face might show two bright spots that look like stars, or sometimes no spot at all. If you see a reflection of a lamp in one eye but not the other, it is likely AI.

So, the next time you see a beautiful face online, peek at the ears and the eyes. If they look like a puzzle that is almost finished but not quite perfect, it is probably AI.
