Accidental atheists? Agent-based explanations for the persistence of religious regionalism

This article outlines a new approach to the study of religious commitment. Starting with a variant on Schelling's classic model of mobility and segregation, we develop a multi-agent religion simulation (MARS) that incorporates insights from theories of religious choice, social influence, and preference formation. Compared to standard statistical methods, MARS does a better job of linking individual choices and collective outcomes. In particular, it demonstrates that stable regional patterns require a balanced combination of attachment to personal identity and adaptation to the social environment.
