The “strain” language is epidemiological modeling vocabulary; it does not make political beliefs biological pathogens. ## Relationships - **extends:** [[wiki/SIR Model|SIR Model]], [[wiki/SEIR Model|SEIR Model]], and related [[wiki/Epidemic Model|epidemic models]]. - **models:** [[wiki/Memetic Contagion and Violent Extremism|Memetic Contagion and Violent Extremism]]. - **network context:** [[wiki/Multilayer Network|Multilayer Network]]. ## Sources / Provenance - [AIMS Mathematics — modeling radicalization under multiple influences, 2022](https://www.aimspress.com/article/id/61cae408ba35de32ad6e8481) - [[research/A Network-Epidemiological Analysis of Radicalization and Real-Time Counterterrorism Observability|Network-Epidemiological Analysis]]
