An internal norm is a pattern of behavior enforced in part by internal sanctions, such as shame, guilt and loss of self-esteem, as opposed to purely external sanctions, such as material rewards and punishment. The ability to internalize norms is widespread among humans, although in some so-called "sociopaths", this capacity is diminished or lacking. Suppose there is one genetic locus that controls the capacity to internalize norms. This model shows that if an internal norm is fitness enhancing…

Questioning the cultural evolution of altruism
It is argued that cultural transmission yields altruism only to the extent that it relies on maladaptive mechanisms, such as conformist imitation and (in some cases) payoff‐biased transmission.
Internalizing cooperative norms in group-structured populations
A model for how intrinsic preferences to adhere to cooperative norms can evolve with and without external enforcement of compliance is presented, using the methodology of preference evolution to model how cooperative norms coevolve with the intrinsic motivations to follow them.
Collective action and the evolution of social norm internalization
Significance People often ignore material costs they incur when following existing social norms. Some individuals and groups are often willing to pay extremely high costs to enact, defend, or

Across the social sciences, a key question is how societies manage to enforce cooperative behavior in social dilemmas such as public goods provision or bilateral trade. According to an influential
Is Cooperation a Maladaptive By-product of Social Learning? The Docility Hypothesis Reconsidered
The docility hypothesis holds that human social learning produces genuinely altruistic behaviors as a maladaptive by-product. This article examines five possible sources of such altruistic mistakes.
Habits of Virtue: Creating Norms of Cooperation and Defection in the Laboratory
These findings help to explain variation in one-shot anonymous cooperation, linking this intrinsically motivated prosociality to the externally imposed institutional rules experienced in other settings.
Altruism may arise from individual selection.
Be nice if you have to--the neurobiological roots of strategic fairness.
Using repetitive transcranial magnetic stimulation, evidence is provided for the causal role of the right DLPFC in strategic fairness and suggests that humans strategically adapt their behaviour and act selfishly if possible but control selfish impulses if necessary.
Reason, Evolution, and the Possibility of Cooperation
“Cooperation” has distinct meanings in biological and moral contexts. In nature, “cooperation” is commonly equated with “altruism,” and involves an apparent fitness cost to the actor. In the moral


The Evolution of Reciprocal Altruism

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
Solving the Puzzle of Prosociality
A model of cultural evolution is developed in which the sociological concept of the internalization of norms is used to explain cultural transmission and the economic concepts of rational action and the replicator dynamic are used to model the interaction between self-interested and altruistic behavior.
Evolution of indirect reciprocity by image scoring
It is proposed that the emergence of indirect reciprocity was a decisive step for the evolution of human societies and the probability of knowing the ‘image’ of the recipient must exceed the cost-to-benefit ratio of the altruistic act.

A haploid sexual two-locus model of gene-culture coevolution is examined, in which a dichotomous phenotype subject to natural selection is transmitted vertically with probabilities dependent on the
Evolution of Indirect Reciprocity by Image Scoring/ The Dynamics of Indirect Reciprocity
It is argued that the emergence of indirect reciprocity was a decisive step for the evolution of human societies and showed that the probability of knowing the image of the recipient must exceed the cost-to-benefit ratio of the altruistic act.
Gene-culture coevolution: models for the evolution of altruism with cultural transmission.
Models of sexual haploids under kin selection are constructed and it is shown that even when Hamilton's conditions for the success of genetically determined altruism are met, genes that increase the transmission of altruism may not invade the population.
Evolutionary Universals in Society
This paper is meant as a contribution to the revival and extension of evolutionary thinking in sociology. It begins with the conception that in the evolution of living systems generally, certain new

Egalitarian Behavior and Reverse Dominance Hierarchy [and Comments and Reply]
Egalitarian society is "explained" chiefly in terms of ecological or social factors that are self-organizing. However, egalitarian behavior is found in a wide variety of social and ecological
