Sex differences on a measure of conformity in automated teller machine lines

Sex differences in conformity were examined as participants approached two ATMs, one of which was occupied by three confederates and the other immediately available. The number of men and women in the line in front of one of the ATMs was manipulated (3 men or 3 women), and an unobtrusive observer recorded the sex of each participant. The results indicated that women were more likely than men to wait in line to use the ATM regardless of the makeup of the line. Thus, the present study provides evidence in favor of the idea that sex differences in conformity are evident on a common task performed in a natural setting.
