# Iatrogenic Security Intervention **Entity class:** Intervention harm concept **Domains:** Countering violent extremism / prevention programs / behavioral state change ## Definition An **iatrogenic security intervention** is a preventive security action that produces the counterproductive state change it was meant to reduce. Because CVE frameworks treat institutional distrust, grievance, and isolation as risk accelerants, an intervention that lowers trust or severs relationships moves participants toward the profile it targets, and a model scoring the post-intervention state reads the change as confirmation of its forecast. The loop validates itself: measured accuracy rises with the harm. ## Documented record The UK government's Independent Review of Prevent (2023) reported that evaluations of some Prevent-funded programs found detrimental effects on participants, including decreased support for freedom of expression and, in three evaluated projects, negative effects on trust in police, government, and media. The review also recorded higher-education concerns that Prevent could chill discussion, reduce trust between students and staff, and deter participation because of uncertainty about how personal information would be used. Human Rights Watch's 2014 *Illusion of Justice* documented federal terrorism cases in which informants played central roles in developing plots and supplying resources, including the Newburgh Four case. ## Evidence ledger - **Established:** counterproductive state change in evaluated prevention programs; informant-centered plot development in documented cases. - **Unresolved:** whether intervention-induced state change functions as a systematic calibration method in any named program. ## Relationships - **prevention programs:** [[wiki/Prevent|Prevent]], [[wiki/Channel Programme|Channel Programme]], and [[wiki/Countering Violent Extremism|Countering Violent Extremism]]. - **operational roles:** [[wiki/Informant|Informant]] and [[wiki/Confidential Informant|Confidential Informant]]. - **contagion model it perturbs:** [[wiki/Complex Contagion of Violent Extremism|Complex Contagion of Violent Extremism]]. - **learning consequence:** [[wiki/Observation-Induced Ground Truth|Observation-Induced Ground Truth]]. - **accounting frame:** [[wiki/The Second Error Function|The Second Error Function]]. - **analysis:** [[research/Harms Incurred While Bringing Preventive Systems Online|Harms Incurred While Bringing Preventive Systems Online]]. - **collection:** [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]]. ## Sources / Provenance - [Independent Review of Prevent's Report and Government Response, GOV.UK](https://www.gov.uk/government/publications/independent-review-of-prevents-report-and-government-response/independent-review-of-prevent-accessible) (2023). - [Human Rights Watch — Illusion of Justice: Human Rights Abuses in US Terrorism Prosecutions](https://www.hrw.org/report/2014/07/21/illusion-justice/human-rights-abuses-us-terrorism-prosecutions) (2014-07-21). **As of:** 2026-09-23
