Scientology is the idea of a very creative mind. Just like all religions. There is a South Park episode all about it that outlines the main ideas. From what I've heard they stop you in the street and invite you to do a test. They then hit you with some bull about you having a low IQ and other failings. In order for you to correct this you pay them a small (for small think large) fee. If you want someone to pick your beliefs for you then I can think of quite a few other religions to choose before Scientology.
