Dr.
Singer’s model of thought reform developed from her work on the tactics
used by cults and cult leaders.  The model is based upon the
following six stages:  
 
1. 
Isolation
2. 
Creation of a
Siege Mentality
3. 
Dependency
4. 
Powerlessness
5. 
Fear and Vulnerability
6. 
Victim is Kept Unaware 
 
The
specific tactics are: 
 
1. 
Keep the person unaware of
what is going on and the changes taking place. 
2. 
Control the person’s time
and, if possible, physical environment. 
3. 
Create a sense of
powerlessness, covert fear, and dependency. 
4. 
Suppress much of the
person’s old behavior and attitudes. 
5. 
Instill new behavior and
attitudes. 
6. 
Put forth a closed system of
logic; allow no real input or criticism.
