The Christians may have been the first to successfully formulate brainwashing, but we have to look to Pavlov, the Russian scientist, for a technical explanation. In the early 1900s, his work with animals opened the door to further investigations with humans. After the revolution in Russia, Lenin was quick to see the potential of applying Pavlov’s research to his own ends.
Three distinct and progressive states of transmarginal inhibition were identified by Pavlov.
The first is the EQUIVALENT phase, in which the brain gives the same response to both strong and weak stimuli. The second is the PARADOXICAL phase, in which the brain responds more actively to weak stimuli than to strong. And the third is the ULTRA-PARADOXICAL phase, in which conditioned responses and behavior patterns turn from positive to negative or from negative to positive.
