This episode explores how extremist ideologies spread online and offline, who is most vulnerable to radicalization, and the pathways that lead people into — and sometimes out of — extremist communities. We discuss the role of social media, traditional media, and even bots in amplifying harmful narratives, as well as the psychological and social vulnerabilities that make individuals more susceptible. We break down the stages of radicalization, from initial uncertainty to community immersion and, in rare cases, violent action. We also considers the impact on families and communities, and what can be done to build resilience and support people away from extremist beliefs.

Content Warning:

We discuss real-world examples of radicalisation and violence that may be disturbing or frustrating for some listeners.
