As an investigative journalist, Julia Ebner had the freedom to do something she freely admits that as an academic (the hat she currently wears as postdoctoral researcher at the Calleva Centre for Evolution and Human Sciences at the University of Oxford) she have been proscribed from doing - posing as a recruit to study violent extremist groups. That, as you might expect, gave her special insight into how these groups attract new blood, and on the basis of that work, as well as more traditional research for groups such as the Quilliam Foundation and the Institute for Strategic Dialogue, she has been hosted by the United Nations, national legislators, intelligence agencies and Big Tech.

In this Social Science Bites podcast, Ebner details some of the mechanics of her undercover research for host David Edmonds before discussing the prevalence and characteristics of violent extremist groups. Given the variety of ways governments tally these groups and the groups' own amorphousness in an online age, determining whether such groups are on the rise - which seems to be a perennial fear - proves devilishly difficult to determine. "I would say," Ebner concedes, "it often comes and goes in waves, but now we are seeing a very strong wave of very young people, including minors, radicalizing towards violence."

That radicalization proves remarkably similar regardless of ideology, Ebner notes. Plus, it's not straightforward determining who might be open to recruitment. "Based on my research, I would say that everyone is potentially susceptible to radicalization, especially in vulnerable moments in our lives, and everyone has them."

Ebner serves up that potential universality in a different context to close the podcast. It's what keeps her up at night: "I think the mainstreaming of some of the extreme concepts and ideas and language that I used to observe only in the darkest corners of the internet, but that is now being heard in parliaments, that is now being seen in large social media channels of influencers or voiced by politicians."

Given her journalistic chops, it is no surprise that Ebner has written extensively on extremism in a series of well received books. The Rage: The Vicious Circle of Islamist and Far-Right Extremism, received the Bruno Kreisky Award for the Political Book of the Year 2018; Going Dark: The Secret Social Lives of Extremists was a Telegraph Book of the Year 2020 and Germany publishing's Wissenschaftsbuch des Jahres 2020 ("Science Book of the Year") Prise as well as the Dr Caspar Einem Prize from the Association of Social Democratic Academics; and Going Mainstream: How Extremists Are Taking Over, was published in 2023.

The relationship between citizens and their criminal justice systems comes down to just that - relationships. And those relations generally start with essentially one-on-one encounters between law enforcement personnel and individuals, whether those individuals are suspects, victims or witnesses.

When those relations get off on the wrong foot - or worse, as in the case of a number of high-profile police killings in the United States attest to - the repercussions can resonate far away from where a traffic stop occurs. This is the field that social psychologist Nick Camp researches. As his website at the University of Michigan explains, Camps studies "the role routine police-citizen encounters play in undermining police-community trust, and how these disparities can be addressed."

As he tells interviewer David Edmonds in this Social Science Bites podcast, "[O]ne of the things that we know from research and procedural justice is that when people don't view policing as legitimate, they're less likely to cooperate with police requests for assistance, for example. Until now, it’s hard to find experimental evidence for this, but one of the things we can use body cameras for is not just to look at disparities in these interactions, but their consequences."

In this episode, Camp cites research on body camera footage, traffic stops, and even first names to describe how anecdotal tropes about often poor police-citizen interactions, especially in the African-American community, are borne out by the reams of data modern recording devices provide. He also offers hopeful signs of improving these relationships with training based on this very same data, and suggests that artificial intelligence might be useful in mining this data for more insights.
