Why do some with radical views become terrorists yet others don't?
Is it possible to identify those who will and will not become involved in terrorism in the future? This question is of central importance to those given the task of assessing the risk posed by individuals who may be on a trajectory toward violence.

those terrorist subsamples with high rates of mental health disorders still fall below 50 percent.
