Interesting research paper on games-theory simulations involving the success rate of various strategies.

The winning strategy appears to be ethnocentrism (cooperating with fellow members of your own ethnicity, but not with those outside your ethnicity) over humanitarian (cooperating with all without distinction) or selfishness (not cooperating with anyone).

My takeaway from reading it, is that an even better strategy for a smaller group practicing ethnocentrism, is to somehow convince the larger group that larger group practicing ethnocentrism is bad.
