The Dark Side of Altruism
The true-crime book Wiseguy , on which the movie Goodfellas is based, vividly portrays the Brooklyn Mafia's social world in the 1950s-70s. A main player in this world, Jimmy "the Gent" Burke, was renowned for his spectacular generosity:
"(Jimmy would) walk in the door (of the makeshift casino) and everybody... would go wild. He'd give the doorman a hundred just for opening the door. He shoved hundreds in the pockets of the guys who ran the games. The bartender got a hundred just for keeping the ice cubes cold. I mean, the guy was a sport..." (p. 28).
Sounds like a great guy, right? Except that besides being extremely generous, Jimmy was also more than just a little psychopathic, known for his joyful indulgence in murder and larceny:
"He seemed to possess a bizarre combination of generosity and enthusiasm for homicide (p. 116)... Jimmy could plant you just as fast as shake your hand. It didn't matter to him. At dinner he could be the nicest guy in the world but then he could blow you away for desert. He was very scary and he scared some very scary fellows (p. 130)... He loved to steal. He ate and breathed it. I think if you ever offered Jimmy a billion dollars not to steal, he'd turn you down and then try to figure out how to steal it from you" (pp. 119-120).
Jimmy, unusual in both generosity and viciousness, is not a typical human. But he nicely exemplifies how seemingly altruistic behaviour can be motivated by brutally selfish concerns. People can boost their own social status through their abilities to benefit and/or harm others, and Jimmy used both generosity and violence to get ahead. In giving money so freely to everyone around him, he bought their respect and dependence on him; he implicitly (and sometimes explicitly) bribed them to stay on his side and never double-cross him. And if he couldn't buy their loyalty with these positive incentives, he was always happy to coerce it instead, via his terrifying personality and enthusiasm for killing.
So generosity doesn't have to be selfless, and can in fact be as used for the same basic purpose—status striving—as clearly ungenerous acts like murder and theft. Even if generosity can often be selfish, however, it doesn't have to be as brazenly selfish as buying people off. Evolutionarily, there were much subtler ways in which generous acts could have enabled ancestral individuals to increase their social status and popularity (and thereby increase their reproductive fitness). Such an act could have signaled, for example, one's own access to resources or empathy, and thus one's attractiveness as a mate, ally, friend or cooperative partner.
