Caption Electropsychometer Model E-AR-40
Additional Information: Security officials used this device, the electropsychometer (or E-meter), in the 1950s and 1960s to help ascertain people’s sexual orientation, assuming that homosexuality made individuals more susceptible to blackmail by enemy agents. Data from the so-called “fruit machine” cost more than 100 civil servants their jobs. The Church of Scientology still uses such machines to assess the mental state of its parishioners.
