Apparently Scientology is quite opposed to both psychiatry/pyschology.

As much as I have recently grown to distrust pharmaceutical treatments I would not place any merit on claims originating from Scientology. I may still watch the video though as I tend to find the amount of crazy beliefs held by what most people seem to consider 'normal' to be quite amusing from time to time. Don't misunderstand, I'm not saying people think Scientologists are normal, just that the basis of their beliefs are predominantly just as irrational, if not more so.
