We developed a model of recruitment to terrorism based on Social Structure Social Learning Theory (SSSL), Routine Activities Theory (RAT) and Situational Action Theory (SAT). Using real-world data, our experiments were enacted in a proto-typical European city borough. After introducing the model and its main results, we critically discuss the decisions taken from the point of view of calibration vs. arbitrary decisions, theory vs. mechanisms, and cost/benefit of modeling choices.
