How agents define neighborhood determines whether segregation emerges

Evidence

Finally, the model was important in demonstrating the significance of an agent’s definition of neighborhood. When agents were programmed to define their neighborhoods narrowly, segregation was a very likely outcome. In contrast, if agents defined their neighborhoods more broadly (e.g., the whole population of agents in a wider region—a city vs. a neighborhood), extreme segregation was far less likely. — Roderick M.
