# Extremism Interdiction Extremism interdiction comprises lawful, evidence-based measures intended to interrupt movement toward violence or organized harm. In the information domain, it can include early narrative detection, off-ramps, trusted intervention, cognitive inoculation, friction at propagation bottlenecks, and restoration of credible alternatives. Interdiction is not the suppression of unpopular belief. Measures should be tied to behavior and credible risk, preserve due process and civil liberties, and be evaluated for displacement, stigmatization, or unintended escalation.

The presence of those forms does not establish that games cause extremism or that a participant is moving toward violence. Analysis must identify the actor, mechanic, platform, audience, function, and observable relationship to conduct. [[wiki/Playable Systems Literacy|Playable systems literacy]] is an upstream intervention. It helps participants recognize the board, role, incentive, feedback, and fiction boundary before continued participation becomes invisible identity work. [[wiki/Non-Substitutability|Non-substitutability]] identifies a different question: whether a person still accepts lawful and symbolic outcomes as meaningful alternatives to direct harm. ## Intervention stack The corpus treats interdiction as a reversible sequence rather than a single classifier: sensing, contextual interpretation, proportionate assessment, trusted off-ramp, remediation, review, correction, and exoneration.
