when you study game theory, one of the first bits you come across is called the 'hawk dove game'. this scenario posits that there is an island of bird people, who are either of the hawk or dove clan. on this island the only source of food is a tuber that it takes two people to dig up. when two hawks score food, they fight and the winner takes all. when two doves score, they share equally. when a hawk and a dove score, the hawk takes all. now when we look at this, an all dove situation is inherently more efficient, because the hawks waste energy fighting. but if you introduce a pair of hawks to an all dove island, they will take over....but when you run the math you find that on a mixed tribe island there are always some doves - in fact, the more violent the hawk's combat, the more the doves persist. this is used to explain how ritualize threat displays evolve, among other things.
now, this is going a bit off the grid and i no longer have the math to prove it, but bear with me. next we introduce a third tribe, the crows. crows fight with hawks and share with doves. this drastically changes the equilibrium number in favor of many more doves. in exploring the evolution of altruism, i added a fourth tribe: jays flee from hawks and crows, steal from doves and share with each other. jays are the cheaters, so to speak, and they also upset the equilibrium, reducing the final number of doves.
if the goal of this is then maintaining a network of reciprocal altruism, doves and crows, then it becomes obvious that the most import trait a bird island person can have is the ability to identify the tribe of other islands, that is to say, to know who to trust. thus intelligence is evolutionarily linked to altruism. i'm talking about Biological Altruism, btw, not philosophical. evolution doesn't give a crap about your feelings
the dark side of altruism is spite (Hamiltonian spite) - actions that have a cost for the actor and a negative impact upon the recipient. this is truly human behavior, rarely seen in other animals. but there's something quintessentially human about being willing to die to punish someone who has harmed your family/people. other animals just don't do that. but in my expanded bird island scenario, it fits - this is how crows deal with jays. crows don't allow jays to flee - they attack them, even though they've already won the food, and despite doing damage to themselves, in order to make the jay's stratagem too costly. and we know this - altruistic networks cannot tolerate cheaters and betrayers, they must make sure such islanders always pay a higher price than what they gain by cheating, which will be the case as long as there are more crows than doves.
does this make any sense to anyone?
