When does a social group reach agreement by imitation processes? I will discuss how we answer this question by considering the voter model, a paradigmatic example of simple model of social behavior. Aspects to be addressed include the role of tie heterogeneity and non persistent ties in social networks, as well as the heterogeneity in the timing of interactions and the coexistence of imitation and rational behavior. I will also discuss the competition between self-organization and external messages or mass media in models of social consensus.
