CAST is working with UCLA and other DARPA performers in a program exploring the process of radicalization and how cognitive neuroscience aid in better understanding of this process. Today, threats from ISIS and other terrorists are increasing worldwide, supported through social media and community contacts. While the horrific results of terrorist acts are well-documented, relatively little is
known about the actual process by which specific individuals are radicalized to the point that they will engage in terrorist acts or join organizations such as ISIS. Web sites maintained by ISIS and others provide instructional material for potential terrorists and a means to recruit them. Important gaps in knowledge concern issues related to the vulnerability of an individual to radicalization, the effects on
the individual level as well as dynamic interactions at the group level and the process by which social media promotes conversion to terrorism.
