Placard describing psychological harassment techniques of the Ministry of State Security in the German Democratic Republic, on display at the Stasi Museum in Berlin. Text: “Psychological harassment measures entailed having the MfS secretly intervene in an individual’s personal life. Psychological methods were applied to unnerve the “target subject”, instilling feat or causing disrepute. Interference in an individual’s personal life was intended to stress and cripple him. Often the “subject target” had no idea why he was experiencing personal and professional setbacks or why friends were distancing themselves from him. People in West Germany were subjected to these measures as well.”
