The cultural theory of risk, often referred to simply as Cultural Theory (with capital letters; not to be confused with culture theory), consists of a conceptual framework and an associated body of empirical studies that seek to explain societal conflict over risk. Whereas other theories of risk perception stress economic and cognitive influences, Cultural Theory asserts that structures of social organization endow individuals with perceptions that reinforce those structures in competition against alternative ones. This theory was first elaborated in the book Natural Symbols, written by anthropologist Mary Douglas[1] in 1970. Douglas later worked closely with the political scientist Aaron Wildavsky, to clarify the theory. Cultural Theory has given rise to a diverse set of research programs that span multiple social science disciplines and that have in recent years been used to analyze policymaking conflicts generally.
