"This article examines a series of Schelling-like models of residential segregation, in which agents prefer to be in the minority. We demonstrate that as long as agents care about the characteristics of their wider community, they tend to end up in a segregated state. We then investigate the process that causes this and conclude that the result hinges on the similarity of informational states among agents of the same type. This is quite different from Schelling-like behavior and suggests (in his terms) that segregation is an instance of macrobehavior that can arise from a wide variety of micromotives."

Henry Farrell contrasts the (mathematically beautiful) Schelling model of spontaneous racial segregation with the (astoundingly ugly) reality of how it was actually violently enforced in Chicago.
