Is it plausible that evolution would gradually push those 70% down to 30% or even lower, given enough time? There may not yet have been enough time for a strong enough group selection in evolution to create such an effect, but sooner or later it should happen, shouldn’t it? I’m thinking a species with such a great degree of selflessness would be more likely to survive than the present humanity is, because a larger percentage of them would cooperate about existential risk reduction than is the case in present humanity. Yet, 10-30% is still not 0%, so even with 10% there would still be enough of selfishness to make sure they wouldn’t end up refusing each other’s gifts until they all starve to death or something.
Can group selection of genes for different psychological constitution in humans already explain why player 1 takes only 70% and not, say, at least 90%, on average, in the game you describe?
What do chimps do? Does a chimp player 1 take more or less than 70%?
First of all, from the standpoint of the good of the group, I see no reason why player1 shouldn’t keep 100% of the money. After all, it is not as if player 2 were starving, and surely the good of player 1 is just as important to the good of the group as is the good of player 2. There is almost no reason for sharing from a standpoint of either Bentham-style utilitarianism or good-of-the-group.
However, there is a reason for sharing when you realize that player 2 is quite reasonably selfish, and has the power to make your life miserable. So, go ahead and give the jerk what he asks for. It is certainly to your own selfish advantage to do so. As long as he doesn’t get too greedy.
