Our objective is to provide Department of Homeland Security (DHS) decision-makers and associated partners with insights about processes extreme ideological groups use to recruit members, harness social identities, mobilize communication around issues, increase commitment to extremism, and incite violent action. Iterating between analyzing extremist microblog archives and lab experiments, our research team is systematically examining messaging content and strategies that foreshadow extreme cognitions, affect, and behaviors. This year's activities focus on English language content most germane to understanding domestic terrorism incidents that may occur within the U.S. Our work provides insights into how messaging content and strategies promoting and foreshadowing violence can be detected, and threats thereby disrupted.
