Abstract: The present study investigated the social determinants required to stimulate consistency in minority members’ attitudes and behavior. The experiment was designed to examine the consistency of individuals in the context of an intergroup belief cross wherein the majority belief (or minority) in a categorical in-group shifted to the minority (or majority) in the out-group. The results indicated that the members of a majority within an in-group consistently preserved their behavioral intentions and beliefs even though they were positioned as a minority within an out-group. That is, the minority members in the whole intergroup context maintained consistency diachronically as a result of support from the majority of their in-group. The theoretical implications on the consistency of minority members, such as whistle-blowers in companies, are discussed.
