Rising Security and Religious Decline: Refining and Extending Insecurity Theory

Explaining the reasons—while not the causes—behind religious decline is a central issue for sociologists interested in secularization processes. Many theoretical perspectives have been proposed over the last decades, and this article focuses on one of them. In particular, it refers to the so-called insecurity theory, formalized by Norris and Inglehart (2011), which reads processes of religious decline in light of the increased security coming with modernization. It summarizes the empirical evidence proposed so far by distinguishing between individual and contextual insecurity and static and longitudinal approaches. Moreover, it underlines the difference between economic and existential insecurity as well as the leading role of socialization processes. From this basis, it provides a summary of the main potential weaknesses of the theory and the main criticisms leveled against it, in order to expand its theoretical relevance and clarify what insecurity theory can, and cannot, tell us about secularization processes.
