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 what makes people behave the way they do, why you can trust some people and not others. It has given me the ability to know which people to trust and which to steer clear of, how to bring even these people to a state where you can trust them.
