How people become radicalized terrorists

Guests: Clark McCauley, Sophia Moskalenko, Anthony Lemieux

What drives people to commit acts of terrorism that claim scores of human lives? On Sunday, a Taliban suicide bomber killed 70 people, many of them children, in a public park in Lahore, Pakistan. Last week, coordinated attacks in Belgium by the Islamic State killed 35 and injured 300. Not to mention the acts of violence by homegrown terrorists in America. So how do people become radicalized and can we predict who is vulnerable to militant messages? This hour, Marty talks with three researchers about the psychology of terrorism. Her guests are CLARK MCCAULEY, research professor of psychology and co-director of the Solomon Asch Center for the Study of Ethnopolitical Conflict at Bryn Mawr College, SOPHIA MOSKALENKO, researcher at the National Consortium for the Study of Terrorism and Responses to Terrorism, and ANTHONY LEMIEUX, associate professor of communication and associate director of the Global Studies institute at Georgia State University.
