“…Many studies on extremist and terrorist transmission conceptualise learning as a process undertaken by individuals (e.g. Hundeide, 2003;Pearson, 2015;Wilner & Dubouloz, 2011), with some narrowing the focus to specific types of people, for example, children who fall into the hands of militant groups (Horgan et al, 2017;Hundeide, 2003), novices who join ideological cells or networks (Everton, 2016;Kenney, 2017Kenney, , 2018Wali, 2017), or those who seek to identify with or model themselves on radical exemplars (Crone, 2016;Körner & Staller, 2018). Other studies have looked at learning from the perspective of groups, for example, with a focus on how recruits or converts acquire new knowledge and skills (Galonnier & de los Rios, 2016;Inge, 2016;Wiktorowicz, 2005), how charismatic leaders transmit their teachings to followers (Beekers, 2015;Gendron, 2017;Wali, 2017), or how groups learn from one another (Morrison, 2017;Ranstorp & Normark, 2015).…”
