Social media algorithms that personalize user content pose a significant concern for American national security because they have the potential to intensify “reinforcing spirals” (Slater, 2007) that can lead users toward extremism. Our previous work (Le et al., 2019) has shown that algorithmic personalization is higher for populations with extreme ideological beliefs; therefore, there is an urgent need to identify factors that make one vulnerable to radicalization online. Our overall objectives for this project are, first, to identify the technological, psychological, and cultural factors that contribute to radicalization of vulnerable populations on social media and, second, to develop tools that can identify and predict radicalization on social media.
