 the origins of tastes and the parameters of the utility function by social influences, training, education, and the like.The exogeneity of tastes (preferences) in this model is the major distinction from "homo sociologicus," in which tastes are taken as partially or even totally determined by the societal environment (see below).Further critics, learning from the broadly defined psychoanalytic tradition, criticize the "homo economicus" model as ignoring the inner conflicts that real-world individuals suffer, as between short-term and long-term goals ("e.g.," eating chocolate cake and losing weight) or between individual goals and societal values.
