Experimental behavioral scientists have found consistent deviations from the predictions of the canonical model of self-interest in over a hundred experiments from around the world. Prior research cannot determine whether this uniformity results from universal patterns of behavior, or from the...

Recent investigations have uncovered large, consistent deviations from the predictions of the textbook representation of Homo Economicus: in addition to their own material payoffs, many experimental subjects appear to care about fairness and reciprocity and reward those who act in a cooperative...
