Fast, slow and endless variation drives global development.

This article explores the dynamics of institutional adaptation in fast-growing, highly interconnected polities in the developing world, and challenges the thesis in modernization theory which posits that economic growth and thus higher per-capita income lead over time to democracy. One mechanism often proposed to explain this link is the idea that economic growth and higher per capita income in a society lead individual citizens in that society to become more receptive to democratic values and norms, and that this receptivity can pave the way for the birth of democracy. Yet evidence increasingly demonstrates that the link is at best tenuous and often not empirically valid. Why have many fast-growing economies and modernizing societies not made a transition to democracy, as predicted by modernization theory? This paper addresses this question, with ideas from complex adaptive systems and evolutionary social psychology, as well as case analyses of Turkey and China. [ABSTRACT FROM AUTHOR]
