The present study in attempting to measure the relationship between racial attitudes and overt behavior askedSsto pose for a photograph with a Negro of the opposite sex. Discrepancies between verbal attitudes and subsequent overt behavior involving those attitudes was found in 59 percent of the cases. The relationship between attitude (prejudice) and behavior (discrimination) is seen to be a function of the level of social involvement with the attitude object as well as the amount of prior experience with it. One implication of the study is that statements or predictions of racial behavior based on attitude measurements have little reliability unless first validated empirically.
