Homo economicus
Another weakness is highlighted by economic sociologists and anthropologists, who argue that "Homo economicus" ignores an extremely important question, i.e. 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).
