The results of this paper and its refutation of racism do not surprise me in the slightest. I recently opened book Economic Indeterminacy by Yanis Varoufakis and apparently, he was conducting some experiments in the past that support his theory about economic origins of discrimination and dominance hierarchy. Basically, what he seems to claim is that while discrimination might be completely unfounded in reality, it will set in as a mechanism to determine and stabilize equilibrium in some economic games. And once the equilibrium is determined, discrimination will actually start to make sense for the game players, ex post facto. The book is unfortunately quite technical, but I have to say I was impressed, Varoufakis certainly is a smart guy. I wish somebody would write a more approachable popular summary of this and other conclusions in the book. Perhaps Varoufakis did himself in his other books, I didn't read any, but I think I will have to at some point.
