Samenvatting

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 (<i>hybris</i>) 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.
