Olweus (1978; 1993), the number of scholars that have been investigating bullying has increased tremendously. A simple search on web of science shows that from 2010 to 2014 (May), 2,736 articles were published with “bully*” in the title, whereas the same search results in 745 studies from 2000 to 2005 and 1,377 studies from 2005 to 2010. That bullying is studied so intensively can be understood because systematic victimization by peers may have severe consequences for victims (see for an overview of studies: Arseneault, Bowes, & Shakoor, 2009; see for meta-analyses: Hawker & Boulton, 2000; Reijntjes, Kamphuis, Prinzie, & Telch, 2010). Also bullies may face negative consequences such as heightened risk of violent, aggressive, or criminal behaviors (see for meta-analytic reviews: Ttofi, Farrington, Lösel, & Loeber, 2011; Ttofi, Farrington, & Lösel, 2012). If insights generated by research on bullying are successfully implemented in anti- bullying programs (which are on average successful in reducing bullying by 20-23 percent, see Ttofi & Farrington, 2011), investments in bullying research can be regarded as preventing both crime
