Socially Enforced Nepotism: How Norms and Reputation Can Amplify Kin Altruism
Kin selection, which can lead organisms to behave altruistically to their genetic relatives, works differently when-as is often the case in human societies-altruism can be boosted by social pressure. Here I present a model of social norms enforced by indirect reciprocity. In the model there are many alternative stable allocations of rewards ("distributional norms"); a stable norm is stable in t...
متن کاملKin altruism, reciprocal altruism and social discounting
According to evolutionary psychologists, human pro-social behaviour is regulated by evolutionarily developed psychological mechanisms whose role is to solve adaptive problems. The same reasoning can be applied to social discounting, i.e. subjective devaluation of a reward which must be shared with one or more people. Based on reciprocal altruism and inclusive fitness theories, hypotheses were f...
متن کاملKin-recognition abilities and nepotism as a function of sociality.
Despite widespread interest in kin selection and nepotism, relatively little is known about the perceptual abilities of animals to recognize their relatives. Here I show that a highly nepotistic species, Belding's ground squirrels (Spermophilus beldingi), produces odours from at least two sources that correlate with relatedness ('kin labels'), and that ground squirrels can use these odours to m...
متن کاملKin Altruism, Reciprocal Altruism, and the Big Five Personality Factors
The purpose of this study was to identify personality characteristics associated with kin altruism and reciprocal altruism, and to relate those characteristics to the Big Five personality dimensions. We hypothesized that traits such as empathy and attachment mainly facilitate kin altruism, and that traits such as forgiveness and non-retaliation mainly facilitate reciprocal altruism. Self-report...
متن کاملAltruism, dispersal, and phenotype-matching kin recognition.
We investigate the coevolution between philopatry and altruism in island-model populations when kin recognition occurs through phenotype matching. In saturated environments, a good discrimination ability is a necessary prerequisite for the emergence of sociality. Discrimination decreases not only with the average phenotypic similarity between immigrants and residents (i.e., with environmental h...
