Some critics of Scientology, such as Bent Corydon, assert that the use of loaded language is a manipulation tool, for example Hubbard's rule that criticizing Scientology means you have hidden crimes against Scientology. Psychiatrist Robert Jay Lifton defines "loaded language" as a technique used in brainwashing. The structured language places more requirements on the student to learn concepts and words, shifting responsibility away from the top administration and the creator of Scientology as well as inhibiting the student's own personal power of choice in thinking since he cannot make his own personal interpretations of the meaning. Only Hubbard's meaning is valid. Period! So the indoctrination boils down to: "Do what Ron says!"
