Was his development of Scientology’s technology based on valid science? Is the Personality Test valid science? Is the E-meter? Is auditing?
The stated goals are:
"A civilization without insanity, without criminals and without war, where the able can prosper and honest beings can have rights, and where man is free to rise to greater heights, are the aims of Scientology."
Was his development of Scientology’s technology based on valid science?
As valid a scientific basis as Freudian analysis. (IWO, no not really. Calling anything "valid science" with regards to psychology and spirituality is at best a strain.)
Is the Personality Test valid science?
It was swiped from a "scientifically valid" test: "Originally called "American Personality Analysis", but probably changed to "Oxford Capacity Analysis" (OCA) because "Oxford" carries more weight. The original test was created by psychologist Julia Lewis and was later adopted and edited by CoS."
Is the E-meter?
It's a valid as a lie detector. It came directly from galvanic skin response meters popularly used by psychologists in the era when scientology adopted it.
Is auditing?
Is psychiatric 'talk therapy'?
