History repeats itself, Marx famously warned, first as tragedy and then as farce. In the case of U.S. torture psychologists, the ” tragedy” occurred half a century ago when CIA-funded psychological research on electroshock treatment, sensory deprivation and the like found its way into the Agency’s counterintelligence interrogation manual. The 1963 KUBARK Manual and its later iterations were used widely by U.S. intelligence and disseminated to other governments in Latin America and Southeast Asia. The “farce” was played post-9/11, as psychologists became involved once again in aiding counterintelligence interrogators.
