Ideological Transmission in Extremist Contexts: Towards a Framework of How Ideas Are Shared

ABSTRACT Despite their centrality in academic and policy debates about radicalization and political violence, ideologies have been conceived narrowly, as cognitive, top-down, coherent and systematic. In general, those who have used the concept of ideology have failed to draw on ideological theory or on recent insights about its practice and embodiment, or location in space and time. Our interest is less in the content of ideology than in how it is shared by those for whom it matters. We offer an interpretive framework, based on six key questions about ideological transmission: What ideas, beliefs, and values are shared, how and why, by whom, and in which spatial and temporary contexts? Following a discussion about the methodological pros and cons of the framework, it is tested on a series of interviews with members of Aum Shinrikyo, the Japanese religious group responsible for the Tokyo subway attack in 1995. We assess the strengths and limitations of the framework for analysing the various dimensions of ideological transmission before considering what it adds to our understanding of the relationship between extreme beliefs and violent behaviour.
