Document Summary

Selfish: biologists classify social interactions according to costs and benefits to actor and recipient, mutualism and altruism are considered cooperative behaviors. It has always been a core principal of human life: quote from cicero (ancient roman, (cid:862)i o(cid:449)e you o(cid:374)e(cid:863) is esse(cid:374)tially a universal expression. What are the neural circuits that support reciprocal altruism in humans: p(cid:396)iso(cid:374)e(cid:396)"s dile(cid:373)(cid:373)a (pd) is an economic game with a payoff structure. 2 years/2 years: hypothetical situation where you and partner have both been brought in for a serious crime but authorities only have enough evidence to commit you of a lesser crime. They separate you into different rooms and try to get you to confess to the more severe crime. You are best off if neither confess and worst off if neither confesses. /: economists predict that both players will be rational and defect. The rational response in a single-shot game is mutual defection (called the nash equilibrium point)
