- People are put in physical or emotionally distressing situations;
- Their problems are reduced to one simple explanation, which is repeatedly emphasized;
- They receive unconditional love, acceptance, and attention from a charismatic leader or group;
- They get a new identity based on the group;
- They are subject to entrapment (isolation from friends, relatives and the mainstream culture) and their access to information is severely controlled
(Psychology 101, Carole Wade et al., 2005)
