An experiment was conducted to determine the importance of stigma in the experience of deviance. Male college students participated in an opinion exchange on important political and social issues. Each subject was made to feel that he was, on most issues, in the minority but in agreement with one other group member. Two variables were manipulated during the exchange: stigma (the minority was either derogated by the majority, or there was no reaction to the opinion differences) and public versus secret minority status of subject (either the subject announced his opinions to the group or merely listened to the opinions of others.) The variables were manipulated orthogonally. After the opinion exchange, the subject rated the attractiveness of the others in the group and then took part in a disguised test of social influence. Results suggest that only when minority members are stigmatized do they feel and act like social deviants. This was reflected in more frequent reports of a desire to change during the exchange, actual changes of opinion during the exchange, ambivalence toward fellow minority members, and greater susceptibility to social influence from a fellow minority member in the public-stigma condition. The reactions of subjects in the absence of stigma suggest that minority status alone is not sufficient to produce feelings of deviance or the behavior usually attributed to social deviants. Deviance, as a social category, includes diverse types of individuals and groups. A contemporary listing (Goffman, 1963) includes "prostitutes, drug addicts, delinquents, criminals, jazz musicians, bohemians, gypsies, carnival workers, hobos, winos, show people, full-time gamblers, beach dwellers, homosexuals, and the urban unrepentant poor [pp. 143-144]." More general lists (e.g., Clinard, 1963) have included the mentally ill and members of racial and ethnic minorities. Although it is agreed that there are special consequences for those included in this category, the necessary and sufficient conditions for placement are subject to debate.
