The conjecture was formulated that people who talk openly in group sessions revealing their secrets are also prone to display their bodies ("no cover-up"). Half the group consisted of patients, the other half were college students. The group leaders evaluated revealing and the group members answered questionnaires concerning background, social behavior, body display, lying, and conformity.
The conjecture was confirmed for the men, but not for the women. In women a correlation of disclosure and body display was found only in reference to the socially acceptable nudity during sexual intercourse. The following findings of the Kinsey reports were corroborated in spite of using a different technique and population: more exhibitionistic tendencies were found in men than in women, in those with higher education than with less education, and in those under 40 compared to older people.
