The goals of the current study were to apply the construct of stereotype accuracy to the domain of college women’s perceptions of the effects of full-time maternal employment on children. Both accuracy/inaccuracy and positive/negative direction were examined. Participants were 1,259 college women who provided stereotyped projections about the effects of full-time employment on children’s IQ scores, formal achievement tests, school grades, and internalizing and externalizing behavior problems. Their stereotype effect sizes were compared to meta-analytic effect sizes used to estimate the "actual" effects of maternal employment on children. Individual differences in these stereotypes were also examined. Results indicate that, on average, college women overestimated the negative effects of full-time maternal employment on child outcomes, especially behavior problems. Significant variability in the direction and accuracy of the stereotypes was explained by individual characteristics such as gender ideology, extrinsic work values, and beliefs about the costs of maternal employment. Concerns are that college-educated young women may retreat from the labor force due to stereotypes about the effects of their future employment on children. Efforts by researchers, practitioners, and policy makers should be directed toward disseminating accurate information and dispelling myths about the likely impact of maternal employment on children’s development.
