     The paper investigates the possibility of cultural polarization in increasingly nonlocal societies, assuming that 1) agents have a large range of interaction, and 2) the similarity between agents is not crucial for an interaction to occur. Plurality information feedback, a filtering effect, and multi-copy of features are identified as candidates for inducing polarization. We show that rapid segregation of minorities by any of these three candidate effects at an early stage makes it possible to observe polarization. In a society where agents have a large range of interaction, polarization is observed as diasporas, and a few subcultures can survive. If the importance of the similarity for interactions decreases, a society can reach equilibrium faster and less cultural heterogeneity remains in it. Excessively large effects of the mass media, in some cases, disturb a society in the sense that it takes longer to settle down in a stable state, but greatly contribute to convergence in other cases. A formal proof showing that reaching equilibrium is equivalent to having a similarity of either zero or one with any accessible agent is provided. Here, we investigate equilibrium states, not states arising at a predetermined large step in computer simulations.
