Document Summary
What you look like (either comparing yourself to almost certain kin or by looking at yourself) You need to know what the individual you are trying to match to looks like. Heterogeneous are used to being around people who are more dissimilar whereas individuals in homogeneous are used to looking the same as those around them: what are the major systems of sociality among non-kin. Because there might be a cost for behaving to their reputation when they are not anonymous. Recall- prisoners dilemma: you can cooperate at a cost k to provide a benefit v to your partner who can do the same. Therefore d is an ess, but c is not: but what if players could engage in direct reciprocity. A strategy that fares well in computer tournaments is tit for tat (tft), a conditional form of cooperation. By corollary, fitness between partners is relative and zero-sum: my success is your failure, and vice versa.
