Integrating Evolutionary Game Theory and Cross-Cultural Psychology to Understand Cultural Dynamics

In this article, we show that an evolutionary game theoretic (EGT) modeling approach can be fruitfully integrated with research in cross-cultural psychology to provide insight into cultural dynamics. EGT was initially developed to model biological evolution, but has been increasingly used to study the evolution of human behavior. Through "virtual experimentation," EGT models can be used to test the effects of various factors on the trajectories of behavioral change at the population level. We illustrate how EGT models can provide new insights into processes of cultural adaptation, transmission, maintenance, and change. We conclude with the strengths and limitations of using EGT to study cultural dynamics and new frontiers that await investigation. Public Significance Statement In today's globalized world, it is critical to understand processes of cultural dynamics. Here we illustrate how evolutionary game theory can be fruitfully integrated with research in cross-cultural psychology to understand cultural adaptation, transmission, maintenance, and change.
