This paper presents a simple mathematical model that shows how economic inequality between social groups can arise and be maintained even when the only adaptive learning processes driving cultural evolution increases individual's economic gains. The key assumption is that human populations are...

This paper lays out an evolutionary theory for the cognitive foundations and cultural emergence of the extravagant displays (e.g., ritual mutilation, animal sacrifice, and martyrdom) that have so often tantalized social scientists, as well as more mundane actions that influence cultural learning...
