# Terror Contagion Hypothesis
**Entity class:** Theory of violent-radicalization diffusion
**Maturity:** Developed
## Definition
The **Terror Contagion Hypothesis** models violent radicalization as a feedback system in which completed attacks broadcast ideological and methodological scripts, high-risk audiences filter those scripts, and later violence renews the informational reservoir. It attempts to connect decentralized “swarm” dynamics with active recruiter or “fisherman” networks.
