Query: Explaining Recruitment to Extremism: A Bayesian Contaminated Case
  Control Approach   Who joins extremist movements? Answering this question poses considerable
methodological challenges. Survey techniques are practically infeasible and
selective samples provide no counterfactual. Assigning recruits to contextual
units provides one solution, but is vulnerable to problems of ecological
inference. In this article, we take inspiration from epidemiology and the
protest literature and elaborate a technique to combine survey and ecological
approaches. The rare events, multilevel Bayesian contaminated case-control
design we propose accounts for individual-level and contextual factors, as well
as spatial autocorrelation in the incidence of recruitment. We validate our
approach by matching a sample of Islamic State (ISIS) fighters from nine
Muslim-majority countries with representative population surveys enumerated
shortly before recruits joined the movement. We find that high status
individuals in their early twenties who had university education were more
likely to join ISIS. We find more mixed evidence for relative deprivation.
