A better understanding of how support evolves online for undesirable behaviors such as extremism and hate, could help mitigate future harms. Here we show how the highly irregular growth curves of groups supporting two high-profile extremism movements, can be accurately described if we generalize existing gelation models to account for the facts that the number of potential recruits is timedependent and humans are heterogeneous. This leads to a novel generalized Burgers equation that describes these groups’ temporal evolution, and predicts a critical influx rate for potential recruits beyond which such groups will not form. Our findings offer a new approach to managing undesirable groups online – and more broadly, managing the sudden appearance and growth of large macroscopic aggregates in a complex system – by manipulating their onset and engineering their growth curves.

Acts of terror lead to both a rise of an extended sense of fear that goes beyond the physical location of the attacks and to increased expressions of online hate. In this longitudinal study, we analyzed dynamics between the exposure to online hate and the fear of terrorism after the Paris attacks in November 13, 2015. We hypothesized that exposure to online hate is connected to a perceived Zeitgeist of fear (i.e., collective fear). In turn, the perceived Zeitgeist of fear is related to higher personal fear of terrorism both immediately after the attacks and a year later. Hypotheses were tested using path modeling and panel data (N = 2325) from Norway, Finland, Spain, France, and the United States a few weeks after the Paris attacks in November 2015 and again a year later in January 2017. With the exception of Norway, exposure to online hate had a positive association with the perceived Zeitgeist of fear in all our samples. The Zeitgeist of fear was correlated with higher personal fear of terrorism immediately after the attacks and one year later. We conclude that online hate content can contribute to the extended sense of fear after the terrorist attacks by skewing perceptions of social climate.

In the 1990s and early 2000s, there was much discussion about the democratic and anti-democratic implications of the Internet. The latter particularly focused on the ways in which the far-right were using the Internet to spread hate and recruit members. Despite this common assumption, the American far-right did not harness the Internet quickly, effectively or widely. More recently, however, they have experienced a resurgence and mainstreaming, benefitting greatly from social media. This chapter examines the history of their use of the Internet with respect to: (1) how this developed in response to political changes and emerging technologies; (2) how it reflected and changed the status of such movements and their brand of hate; and (3) the relationship between online activity and traditional methods of communication.
