 In a study by Reitan and Shaw, it was found that men and women conformed more when there were participants of both sexes involved versus participants of the same sex.Subjects in the groups with both sexes were more apprehensive when there was a discrepancy amongst group members, and thus the subjects reported that they doubted their own judgments.Sistrunk and McDavid made the argument that women conformed more because of a methodological bias.
