Natural Kantian Or Zoo Economicus? Evolutionary Theories Of Selfishness And Altruism Among Men And Beasts, Ted C. Bergstrom
Ted C Bergstrom
This paper addresses the question of whether our evolutionary history suggests that humans are likely to be individually selected selfish maximizers or group selected altruists. It surveys models from the literature of evolutionary biology in which groups are formed and dissolved and where the reproductive success of individuals is determined by their payoffs in a game played within groups. We show that if groups are formed randomly and reproductive success of group founders is determined by a multi-person prisoners’ dilemma game, then selfish behavior will prevail over maximization of group payoffs. However, interesting models can be found for which “group …

Evolution Of Social Behavior: Individual And Group Selection, Ted Bergstrom

How selfish does our evolutionary history suggest that humans will be? We explore models in which groups are formed and dissolved and where reproduction of individuals is determined by their payoffs in a game played within groups. If groups are formed ``randomly'' and reproductive success of group founders is determined by a multi-person prisoners' dilemma game, then selfish behavior will prevail over maximization of group payoffs. However, interesting models exist in which ``group selection'' sustains cooperative behavior. Forces that support cooperative behavior include assortative matching in groups, group longevity, and punishment-based group norms.

Does Mother Nature Punish Rotten Kids?, Ted Bergstrom, Carl Bergstrom

The theory of parent-offspring conflict predicts that mothers and their offspring may not agree about how resources should be allocated among family members. A kid, for example, may favor a later weaning date than does its mother. Despite the mother's physical superiority, it may be that the kid is able to manipulate her behavior. In this paper, we investigate a two-locus population genetic model of weaning conflict in which offspring can attempt to extort resources from their parents by reducing their own chances of survival if their demands are not met. We find that the frequency of recombination between the …
