Scenario J

Men are recruited to participate in an experiment on sexual attitudes, although they are not told that it is actually a study of attitudes toward homosexuality. Participants are led to believe that a "psychogalvanometer" used in the experiment is capable of detecting sexual arousal. They are also told that if the galvanometer registers arousal when an individual looks at slides of nude males, the individual is probably a latent homosexual. The galvanometer is rigged so that all participants are led to believe they are latent homosexuals. Following the experiment, the researcher informs the participants that the galvanometer was rigged, and he gives detailed information about the study and its true purpose.
