In the aftermath of the New Zealand mosque attacks, we explore the psychological factors that cause a person to commit heinous acts of mass violence, technology’s role in spreading extremist propaganda and what governments and communities can do to prevent terrorism.

Kruglanski, PhD, an APA fellow and distinguished university professor in psychology at the University of Maryland, who is an expert on terrorism, radicalization and deradicalization.
