Have We Evolved to Be Nasty or Nice?
It is futile to ask whether people are naturally cooperative or selfish. They can be either, in different circumstances.

A new study by Dirk Helbing at ETH Zurich in Switzerland and colleagues has modeled the emergence of “nice” behavior in idealized human beings. It’s done by computer, using the famous “prisoner’s dilemma” game, in which a prisoner has to decide between cooperating with a comrade to get a mutual reward or avoiding a punishment by being the first of the two to defect to the other side. The Zurich team found that so long as players in the game stay near their (modeled) parents, the birth of a nice guy predisposed to cooperate can trigger “a cascade” of generous acts.
In other words, more togetherness and physical proximity across the generations allows the development of more prosocial behavior. “The clustering of friendly agents, which promotes other-regarding preferences, is not supported when offspring move away.” They also argue that networking via social media can promote niceness, which might surprise regular users of Twitter.
