Sex differences in self-confidence: The influence of comparison to others' ability level

Previous investigators have suggested that women display lower self-confidence than men in almost all achievement settings. The validity of this suggestion is assessed in an experiment testing the impact of comparison to others upon sex differences. Male and female undergraduates, who expected to cooperate in the future with a same-sex partner of high, average, or low ability, selected a difficulty level for an achievement test, completed the test, evaluated their own performance, and estimated their future partner's probable performance. As predicted, only when subjects' future partner was highly competent did women select an easier test than men, perform less well, and compare themselves less favorably to their partner. Also, women's, but not men's, self-evaluations depended upon their partner's ability level. It is concluded that sex differences are moderated by social comparison variables. Cognitive processes that may underlie such differences are discussed.The authors wish to express their appreciation to Phoebe Ellsworth for her critical comments on this research, and to Pamela Joy, Tama Jacobson, and Thomas Hallet for serving as experimenters. Portions of this study were reported at the Eastern Psychological Association Convention, 1978.
