This article joins the debate over institutional change with two propositions. First, all institutions are syncretic, that is, they are composed of an indeterminate number of features, which are decomposable and recombinable in unpredictable ways. Second, action within institutions is always potentially creative, that is, actors draw on a wide variety of cultural and institutional resources to create novel combinations. We call this approach to institutions creative syncretism. This article is in three parts. The first shows how existing accounts of institutional change, which are rooted in structuralism, produce excess complexity and render the most important sources and results of change invisible. We argue that in order to ground the theory of creative syncretism we need a more phenomenological approach, which explains how people live institutional rules. We find that grounding in John Dewey's pragmatist theory of habit. The second part of the article explains Dewey and shows how the theory of habit can ground an experiential account of institutional rules. The third part presents a field guide to creative syncretism. It uses an experiential approach to provide novel insights on three problems that have occupied institutionalist research: periodization in American political development, convergence among advanced capitalist democracies, and institutional change in developing countries.Institutions explain a lot: national variation in capitalism and the welfare state, counterintuitive paths of political development, policy variation within nation states, and why some societies grow while others stagnate. But they have less success in explaining their own transformation, the nature of informal politics and economy, entrepreneurship, and diversity within their own boundaries. As institutionalists have turned to these problems, they have questioned structural and deterministic principles Theor Soc (2009) 38:543-580
