cooperation, including those actions maintained by indirect reciprocity, in the first place. I expose the false presuppositions behind this claim and argue that altruism as fairness is not incompatible with natural selection. View all » Common terms and phrases. Sensitivity to cues of, these parameters and their net effect on fitness would account for a degree of nonrandom, Such, perhaps, is the adaptive value of the refined moral systems characteristic of extant, human groups, where the proceeds from indirect reciprocity arguably have grown to be more, relevant to decision making than did the proceeds from continued group persistence. At the close of his first inaugural address, Abraham Lincoln spoke to those who would divide the United States. A, parallel dynamic best explains the overarching cooperation of genetic elements temporarily, united in a genome. Evolution of indirect reciprocity by image. The hypotheses developed here clearly depend on the interests of groups of individuals. “We are not enemies, but friends. recognize. vulnerability of the group to fast-acting extrinsic sources of group instability.

Trivers, R. (1971). Download Citation. Some writers, often extrapolating from economic models, have hypothesized a general, tendency of cooperation either to decay or to fluctuate in regular boom and bust cycles, tendencies, for cooperation to be maintained and group persistence to be assured over time, a, certain specialized trait must have evolved and persisted at some threshold level in the, an alternative explanation for the persistence of groups. Trade-offs may be obscured by insufficient selective time, noisy or fluctuating selective environments, and weak selection pressures. Therefore, the second, principle we propose is the group stability insurance function of morality, features of human morality are adaptive primarily because they, fast-acting threats. and religion have evolutionary and cultural roots in the social behavior of our ancestors Such status-by-stability interactions also become important when stability is, leaving, but leaders will benefit by keeping others in the group, providing an incentive to. less critical. These hypotheses deserve testing for at least three reasons. This is the point at which many evolutionary, studies of human behavior apply the terms altruism and selfishness, a misleading dichotomy, that begs the question of which course of action is, in fact, adaptive for an individual in a, given situation. This interaction accounted for significant variance independent of C. E. Rusbult's (e.g., see record 1981-10400-001) investment model of CM in the face of AD. Diana Rigg. the optimal level of cooperation in a given situation. Humans expend significant effort debating the, validity of claims of selflessness and bestowing praise for actions deemed selfless. The more that group stability is threatened, the more that, group service is likely to be adaptive for an individual, while the more successful or stable the, group, the more adaptive is the relaxation of individual commitment to the group and an, increase in self-serving behavior because the detriment to group stability of such relaxation is, small. We watched Americans unit-ed for a common purpose. I argue that the contested role of morality is rooted in the profoundly ambivalent consequences that morality has on market efficiency. However, groups in this situation would still be susceptible to fast-acting. Defined along the same lines, an agent is called ‘altruistic’ if an interaction results in a net loss to himself and a net benefit to his partner.
