Three studies were conducted to investigate stereotypes of men of various hair colors by middle-class Anglo college students. Study 1 found an increase of perceived blondness with status, while lack of status was associated with red hair. Study 2, using semantic differentials (after Osgood), found blonde males to be significantly more beautiful, active, strong, pleasant, clean, sharp, powerful, rich and successful than red-headed males. The redheaded male concept clustered together with concepts of sick, scum and fool, and was closer to the concept of janitor and further from the concept of doctor than the blond on the dimensions of potency and likeability. Study 3 rated blond, dark haired Anglos, redheaded, Negro, Chicano, and American Indian males. Rated as most beautiful to least beautiful in order were blond, dark, Negro, Chicano, Indian and then redhead. Indian, Negro and Chicano males were not rated as successful as redheads who were rated as less successful than blonds and dark haired Anglo males. The findings indicate a stereotyping, at least with Anglos, of a strong, successful, intelligent, good-looking blond male. Redheaded males are seen as less attractive, less intelligent, masculine, and successful. The findings can be summed up by the title that the redheaded findings have begun to be called by the researchers; the 'Bozo Effect' after a favorite clown. (Author)
