Manipulative groups exist all around us: any social group or relationship can become manipulative. Religious, political and therapy cults, as well as educational, Internet, corporate and marketing cults prey upon people, using all sorts of tricks and traps. Manipulators create one-on-one cults with their partners, and extend their control into the family. Criminals form gangs that have the same dynamics as other cult groups. At worst, manipulators take over whole nations, which then operate as totalitarian cults.
