Post-Scientology Behavioral Patterns

Given that the Scientology world view is very rigidl defined, in both cases, the departure is traumatic to the individual. The degree of trauma varies according to the intensity of the circumstances surrounding the departure, how long the person was in, and how deeply involved they were, and the personality of the individual. As with any trauma, the individual experiences depression, dislocation with the world they suddenly find themselves in, rage, anger, sometimes a desire for revenge. This paper is not intended to be an "exit counselling", since there are experts who specialise in this, and the literature listed at the conclusion adequately identifies these aspects, and suggests strategies for dealing with them.

Rather, what is being highlighted here is the often undetected behavioral patterns, learned while in Scientology, that manifest in an individual long after they have left, even when they feel that they have fully recovered from Scientology. These behavioral patterns can be traced back to specific aspects of Scientology teaching, and what will be outlined is intended as a starting point, and guide, which can be modified, or added to, depending on the reader's own experience and perception.
1. POLARISED THINKING:

By polarised thinking, I am referring to extremist thought patterns, which could even be compared to totalitarian rigidity. Things are either ALL good, or ALL bad, a person is either TOTALLY evil, or TOTALLY good. The individual can unconsciously re-act to life, people and information with this rigid and uncompromising approach. They either love a person, or hate them. A piece of information is either perfectly true, or all lies.
