It's even worse than that since the experiment is based on appearance, but claims it's about race, and race is a social construct. The labels "black" and "white" in the western world are practically meaningless today. "Mixed-race" people are increasingly common, or at least recognized, and the phenotypes associated with "white" and "black" have always been present in people around the world without necessarily having much if any European or African ancestry. EDIT: and similar to what another comment said, this ignores all other notions of "race" besides "black" and "not black"
