In the course of my research writers have often commented on a link between the intelligence agencies and cults. Perhaps one reason is that a cult of people too afraid to ask questions or comment can be used as cover for covert activities such as illegal weapons staching and torture:
The more trauma, the more memory loss, the more cover ….
Power is a manifestation of trauma. No trauma, no power.
Play down the real source of the trauma and encourage your victim to find fault with themselves or anyone but the real source and relief only in your ‘solution’ (the dialectic).
Works on any scale.
