If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Science of Survival.
This book really helped me with understanding my fellows and also knowing what people are capable of doing. There is a chart called the 'Hubbard Chart Of Human Evaluation' which is the result of research into human behavior and how to predict it. This is essential for anyone in close relationship to others.
