 Although some questions of interpretation and challenges of representation exist, an important advantage of the evolutionary approach is that it does not require sophisticated strategic reasoning in circumstances, such as large-group interactions, in which it would be unrealistic to assume it. People are very unlikely to engage in full Bayesian calculations in making decisions about norm adherence. Agents often rely on cognitive shortcuts to determine when norms ought to be in effect given a certain context, and whether or not they should adhere to them. Evolutionary models that employ adaptive learning strategies capture these kinds of cognitive constraints, and allow the theorist to explore how these constraints influence the emergence and stability of norms.
