A formal analysis of cultural evolution by replacement
نویسندگان
چکیده
Social psychologists have used the replacement method to simulate cultural evolution in the laboratory, studying what happens when a group of people performing a task are gradually replaced by new members. We provide a formal analysis of the dynamics of cultural evolution by replacement under the assumption that the people involved are Bayesian agents. We use a connection to a statistical inference algorithm – Gibbs sampling – to characterize the outcome of this process, and show that this analysis can account for both laboratory data and population-level trends resulting from cultural transmission.
