“The men were taught to shoot but also given a special type of ‘Clockwork Orange’ training to quell any qualms they may have about killing. Men are shown a series of gruesome films, which get progressively more horrific. The trainee is forced to watch by having his head bolted in a clamp so he cannot turn away, and a special device keeps his eyelids open.” In psychological terms, this step-by-step reduction of a resistance is a form of classical (Pavlovian) conditioning called systematic desensitization.
