Studying terrorism and radicalization is quite problematic because of a lack of reliable sources. Finding out what motivates terrorists often boils down to educated guessing. The author describes the search for an academic definition of terrorism and summarizes the development of this discipline since the 1970s, thereby distinguishing research on three levels: macro, micro and meso. While before 9/11 few academics were involved in this research field, it ‘exploded’ thereafter. Important factor contributing to this expansion is the greater availability of government funds and relevant data for this type of research. However, the growth of this discipline isn’t just good news, researchers should be aware of a number of pitfalls identified as the proximity to government power, too much self-confidence (hybris) of researchers pretending to have designed a ‘unified theory’, the abundance of funds for this type of research, resulting in a lot of low-quality research, and finally the politicization of the subject, which could limit the academic freedom.

IS propaganda is assumed to contribute to radicalization of Western Muslims. How IS propaganda reaches the hearts and minds of Western Muslims and consequently fuels radicalization is nonetheless an understudied topic. Through content analysis of all fifteen issues of IS-glossy Dabiq this article demonstrates how IS propaganda works in Dabiq. First, IS attunes in Dabiq to factors that foster radicalization according to the literature. IS does so by its discussion in Dabiq of injustice done to Muslims worldwide, the image of the Western enemy, and its positive presentation of the individual and group identity of IS fighters. Second, in Dabiq IS paves the way for embracing violent means, such as terrorist attacks on Western civilians through a discourse of ‘denial’.
