Social value orientations (also referred to as social motives, social values, or value orientations) is a social psychology motivational theory of choice behavior in game situations advanced by David M. Messick and Charles G. McClintock in 1968.[1] Unlike the traditional rational choice theory in mainstream economics, which assumes that all individuals make choices that maximize their own payoffs in social dilemma situations, social value orientations consider personality differences across individuals which leads to a range of preferences for one’s own well-being and the well-being of others.[2]
