I feel like that "corporate wants you to find the differences between these two photos" meme. Isn't everyone in those photos, in both the top and bottom rows, white?

Edit: Ah, I see, OP has given this a highly misleading title. The "whiteness" of the faces is not actually particularly relevant. In another thread someone summarized what the article is actually about:

For anyone who doesn’t want to read the paper, they basically took an 60 white men and 60 white women, and showed them a whole bunch of white faces, half of which were generated by AI. It turns out that AI faces were rated as more human-like than actual humans, and they had some hypothesis why. Principally that AI, by its nature, generates images close to “average”, while real people tend to have features that are not “average”. The reason the study focused on white people is that most AI have been trained on white faces, so AI tends to do better with white faces.
