It does not make an idea a biological pathogen or every exposed person an adopter. The analytic state should distinguish ground truth, observed evidence, inferred state, and predicted state. ## Relationships - **domain router:** [[wiki/Network Epidemiology|Network Epidemiology]]. - **ontology neighbors:** [[wiki/Contact Tracing|Contact Tracing]] and [[wiki/Probabilistic Contact Tracing|Probabilistic Contact Tracing]]. - **synthesis:** [[wiki/Counterterrorism Predictive Graph|Counterterrorism Predictive Graph]] and [[wiki/Predictive Intelligence Loop|Predictive Intelligence Loop]]. - **governance and trust:** [[wiki/Surveillance Purpose Migration|Surveillance Purpose Migration]] and [[wiki/Surveillance Trust Externality|Surveillance Trust Externality]]. - **network-inference bridge:** [[wiki/Contact Tracing as Network Inference|Contact Tracing as Network Inference]]. ## Sources - [National Institute of Justice — Five Things About the Role of Social Networks in Domestic Radicalization, December 2023](https://nij.ojp.gov/topics/articles/five-things-about-role-social-networks-domestic-radicalization) - [Mason Youngblood — Extremist ideology as a complex contagion, July 31, 2020](https://www.nature.com/articles/s41599-020-00546-3) **As of:** 2026-09-23
