A third expert used the TAT and MAPS protocols to evaluate the psychological adjustment of the men. When asked to identify which Rorschach protocols were obtained from homosexuals, the experts could not distinguish respondents' sexual orientation at a level better than chance. They classified two-thirds of the heterosexuals and two-thirds of the homosexuals in the three highest categories of adjustment. Unaware of each subject's sexual orientation, two independent Rorschach experts evaluated the men's overall adjustment using a 5-point scale. Hooker administered three projective tests, which measure people's patterns of thoughts, attitudes, and emotions-the Rorschach, in which people describe what they see in abstract ink blots, the Thematic Apperception Test and the Make-A-Picture-Story Test), in which people tell stories about different pictures. None of the men were in therapy at the time of the study.
The two groups were matched for age, IQ, and education. Evelyn Hooker studied 30 homosexual males and 30 heterosexual males recruited through community organizations.
