'John Horgan’s The Psychology of Terrorism is one of the best applications of a social science discipline (in this case, psychology) to explain the drivers that motivate individuals to become terrorists, function as terrorists, and, in ideal cases, disengage from terrorism. Also included are some of the best treatments in the academic literature on how to define terrorism and conduct academic research on terrorism.' - Foreword Magazine'The structure is clear and sensible and the text should be of value to both undergraduate and postgraduate courses. I recommend it strongly.' - Psychology XIX
