In 1969 and 1971, Schelling published widely cited articles dealing with [[race (classification of human beings)|racial]] dynamics and what he termed "a general theory of [[tipping point (sociology)|tipping]]."<ref>Thomas C. Schelling (1969) "Models of segregation," ''American Economic Review'', 1969, 59(2), [http://isites.harvard.edu/fs/docs/icb.topic185351.files/shelling1.pdf 488–493].<br />&nbsp;&nbsp; _____ (1971). "Dynamic Models of Segregation," ''Journal of Mathematical Sociology'', 1(2), pp. [https://web.archive.org/web/20140801170215/http://www.stat.berkeley.edu/~aldous/157/Papers/Schelling_Seg_Models.pdf 143–186].</ref> In those papers, he showed that a preference that one's neighbors be of the same color, or even a preference for a mixture "up to some limit," can lead to total [[residential segregation|segregation]]. He thus argued that motives, malicious or not, were indistinguishable as to explaining the phenomenon of complete local separation of distinct groups. He used coins on graph paper to demonstrate his theory by placing pennies and dimes in different patterns on the "board" and then moving them one by one if they were in an "unhappy" situation.{{citation needed|date=September 2023}}

Schelling's dynamics has been cited as a way of explaining variations that are found in what are regarded as meaningful differences{{spaced ndash}}gender, age, race, ethnicity, language, sexual preference, and religion.  A cycle of such change, once it has begun, may have a self-sustaining momentum. Schelling's 1978 book ''Micromotives and Macrobehavior'' expanded on and generalized those themes<ref>Thomas C.
