This paper reports a study of conformity reactions of white and black children to the unanimous and incorrect judgment of children from either their own or other ethnic groups. Experimental groups comprised four subjects of the same sex and grade level. Groups representing all Negro were used; all variables were completely crossed. The subjects were 48 male and 48 female seventh and eighth graders from an urban junior high school in Florida. Each sex group was half white and half black in number. The procedure gave the subject fifteen opportunities to conform to the unanimous and incorrect judgment by what appeared to be the other three members of his group. The test related to the area of three different geometric figures drawn on each of 25 different cards. The group appeared to label the smallest figure as having the largest area. Preliminary analyses provided some evidence that in this population conformity is negatively related to intelligence. Additionally, the ethnic group by source of pressure interaction was the only significant source of variance. Whites conformed more to white peers than to black peers, and the whites conformed more to whites than did Negroes to Negroes.
