How do terrorists radicalize followers online?

Radicalization and Ideological Influence Online

So What?

Terrorist groups are increasingly using online platforms to recruit members, mobilize communication around contentious issues, increase commitment to extremism, and incite violence. With this in mind, it’s important that national security professionals understand the messaging strategies of these groups so that they can combat them.

Project Summary

This project explores online messaging strategies and how they may be used to either promote or counter extremist rhetoric. The research team is examining messaging strategies on publicly accessible microblog platforms to understand how terrorist groups and malign actors build an audience among “neutral” observers.

Purpose/Objectives

This project seeks to provide the Department of Homeland Security with insights about the processes terrorist groups use to recruit members, increase commitment to extremism, and incite violence. The project will identify how messaging strategies enhance commitment to terrorism, extremism, and violence, what types of messages precipitate violence, and what messaging can counter extremist rhetoric.

Method

1. Natural language processing of online posts before and after violent events in the U.S.
2. Controlled laboratory experiments
