Article: Group Dianetics in the Foundation
Socio-Political Subversion
Hubbard discusses the black side of Dianetics when it is used to achieve authoritarian power. Hubbard asserts he has the only remedy for Black Dianetics and uses that fact to justify his demand that Dianetics remain safe. 
The only real threat to Dianetics is that its organization will be used for authoritarian power in the world. There is a black side to Dianetics which is seldom stressed but which is most uncomfortably real. Under its past method of management Dianetics was peculiarly susceptible to being taken over by power pushes and has survived two very serious ones only by the swiftest kind of management actions. Thus it must be designed for defense in depth against any type of push, and defense in depth with non rigid lines is the design of the present proposed government.

Unless someone is empty-headed enough to want to rule the world, Dianetics will survive, spread and prosper. These proposals are designed as an effort to make it impossible for Dianetics to be misled by anyone. It has to be made safe from the foibles of man, and man had better be made thoroughly safe from any organization applying Black Dianetics.
