Journal ArticleDOI
The Evolution of Facultative Conformity Based on Similarity.
TL;DR: A gene-culture coevolutionary model is developed that allows cognition to encode and process information about the similarity between naive learners and experienced demonstrators and suggests that social cognition equips people to use conformity in a discriminating fashion that moderates the evolutionary trade-offs that would occur if conformist social learning was rigidly applied.
Journal ArticleDOI
Behavioural homogenization with spillovers in a normative domain
Charles Efferson,Sonja Vogt +1 more
TL;DR: Information about the choices of others led participants to converge rapidly on similar normative evaluations that continued to hold sway in subsequent asocial settings, at least partly owing to the combined effects of conformity and self-consistency.
Journal ArticleDOI
Simple moral code supports cooperation
Charles Efferson,Ernst Fehr +1 more
TL;DR: A study assessing scenarios in which people judge each other shows that a simple moral rule suffices to drive the evolution of cooperation.
Journal Article
Prey-producing predators: the ecology of human intensification.
TL;DR: Two separate modeling frameworks that integrate the two traditions of modeling aggregate consumer-resource systems in a simple and straightforward fashion are developed and analyzed.
Journal ArticleDOI
Pre-existing fairness concerns restrict the cultural evolution and generalization of inequitable norms in children
TL;DR: This article conducted a lab-in-the-field experiment among kindergarten (5-6) and second-grade (8-9) children living in Switzerland (4′228 decisions collected from 326 children) to examine how inequitable norms evolve culturally and whether they generalize from one setting to another.
