Hitchhiking women's hair color.

To test the effect of women's hair color on the frequency of offering help, male (n = 1,508) and female (n = 892) French motorists were tested in a hitchhiking situation. Five 20- to 22- yr.-old female confederates wore a wig with blonde, brown, or black hair. Each confederate was instructed to stand by the side of a road frequented by hitchhikers and hold out her thumb to catch a ride. Blonde hair, compared with brown hair or black hair, was associated with a small but significantly larger number of male drivers who stopped to offer a ride (18 vs 14%). No difference was found for those with brown and black hair (14 and 13%, respectively). No effect of hair color was found for female drivers who stopped. The greater attractiveness associated with blonde hair for women appears to explain these data.
