Social Media

September 11th was a turning point in the understanding of terrorism and radicalization. The Internet has provided an instrumental change regarding how terrorists communicate and spread their propaganda, proving a cause of concern for counterterrorism units. The increased use of social networking platforms has provided a significant change in the process of self-radicalization, with younger ...

Social media platforms have become extremely popular in the last fifteen years. Almost half of the world population has a social media account. This has made social media extremely attractive to extremist groups. Recent studies have shown that extremists use social media platforms for violent radicalisation. They take advantage of the interactional nature of these ...

This report will outline some of the ways social media continues to be exploited 20 years on to promote misinformation, as well as conspiracies that advance bigoted and prejudiced beliefs and ideologies, especially anti-Semitism. ...

The basic issue that this chapter examines is how we set morally justifiable limits on what people say online, with a specific focus on speech acts related to terrorism. The chapter takes as one of its foundational assumptions that there are situations in which free speech, while an important and potentially fundamental right, can be ...

High-impact studies on the wave of right-wing and racist violence in the 1990s and early 2000s established that mass media discourse on immigrants and previous violent incidents had a significant influence on the prevalence of radical right violence. This ...

This paper investigates the link between social media and hate crime. We show that antirefugee sentiment on Facebook predicts crimes against refugees in otherwise similar municipalities with higher social media usage. To establish causality, we exploit exogenous variation in the timing of major Facebook and internet outages. Consistent with a role for “echo chambers,” we ...

The polarizing tendency of politically leaned social media is usually claimed to be spontaneous, or a by-product of underlying platform algorithms. This contribution revisits both claims by articulating the digital world of social media and rules derived from capitalist accumulation in the post-Fordist age, from a transdisciplinary perspective articulating the human and exact sciences. Behind ...

Disrupting the emergence and evolution of potentially violent online extremist movements is a crucial challenge. Extremism research has analyzed such movements in detail, focusing on individual- and movement-level characteristics. But are there system-level commonalities in the ways these movements emerge and grow? Here we compare the growth of the Boogaloos, a new and increasingly prominent ...
