As technology evolves, AI-generated images of human faces are becoming increasingly indistinguishable from real photos. But our ability to separate the real from the artificial may come down to personal biases—both our own, as well as that of AI’s underlying algorithms.
According to a new study recently published in the journal Psychological Science, certain humans may misidentify AI-generated white faces as real more often than they can accurately identify actual photos of caucasians. More specifically, it’s white people who can’t distinguish between real and AI-generated white faces.

In a series of trials conducted by researchers collaborating across universities in Australia, the Netherlands, and the UK, 124 white adults were tasked with classifying a series of faces as artificial or real, then rating their confidence for each decision on a 100-point scale. The team decided to match white participants with caucasian image examples in an attempt to mitigate potential own-race recognition bias—the tendency for racial and cultural populations to more poorly remember unfamiliar faces from different demographics.
“Remarkably, white AI faces can convincingly pass as more real than human faces—and people do not realize they are being fooled,” researchers write in their paper.
This was by no slim margin, either. Participants mistakenly classified a full 66 percent of AI images as photographed humans, versus barely half as many of the real photos. Meanwhile, the same white participants’ ability to discern real from artificial people of color was roughly 50-50. In a second experiment, 610 participants rated the same images using 14 attributes contributing to what made them look human, without knowing some photos were fake. Of those attributes, the faces’ proportionality, familiarity, memorability, and the perception of lifelike eyes ranked highest for…
