In “Sensitivity International: Network for World /Control”, 1970, Ed Dieckmann covers the history of the sensitivity training movement, delving into its Illuminati origins, its use in various forms by Hitler and the communists, and ultimately its wholesale application to American education through the training of teachers in its most subtle and not too subtle techniques. Sensitivity Training is also “coercive persuasion in he form of thought reform or brainwashing,” according to Issues in Training, p. 47, a manual for group leaders published in 1962 by the National Training Laboratories of the NEA.
