 Coexistence of Social Norms based on In- and Out-group Interactions ,

Excerpt: The question how social norms can emerge from microscopic
interactions between individuals is a key problem in social sciences to
explain collective behavior. In this paper we propose an agent-based model
to show that randomly distributed social behavior by way of local
interaction converges to a state with a multimodal distribution of
behavior. This can be interpreted as a coexistence of different social
norms, a result that goes beyond previous investigations.
