Current behavioral economics/game theory and social psychology literature have been captivated by the idea of altruism and egoism. In large part, these two disciplines have tried to determine the foundation of selfish and selfless behavior, without much result. The current chapter examines the root issues associated with this inquiry and argues for a shift in attention towards factors associated with cooperation. As such, empirical research from both disciplines is presented to show the advancements in relation to identification of these factors. Additionally, the authors offer a possible solution to the fractured literature in the form Weber, Kopelman, and Messick's (2004) dual process model in an effort to merge findings from both disciplines in an attempt progress this line of research.
