Dianetics
From Encyclopedia Of Stupid
Dianetics is stupid.
Dianetics basically consists of probing things people are uncomfortable with, while they are hooked to a meter, which measures their skin resistance.
This process is called "auditing," and you pay lots of money for it, and when it has gotten rid of all your Thetan-related hangups, you are a free agent, called a "clear."
