Objective. This article demonstrates how intersection theory can be applied in empirical studies by testing whether an individual's race, class, and gender have interactive effects. Methods. Data on high school students' ratings of the importance of equality, money, career, and family from the Monitoring the Future study are used. A stepwise regression model is employed to determine first whether additive effects exist in the data, and then whether interactions exist among race, class, and gender characteristics. Results. Previous findings of additive effects were generally confirmed in the first stage of the regressions, with some exceptions. For the money and family values, significant interactions exist between some pairs of characteristics, but three-way interactions were not significant. For equality and career values, no significant interactions were found. Conclusions. Although there are times when additive models are sufficient to describe differences among groups, the omission of interaction terms can sometimes lead to misleading conclusions about the effects of race, class, and gender. Using intersection theory in empirical models will guard against this oversight and may lead to a broad theory of when significant race, class, and gender interactions should be expected.In a 1983 article on sex role attitude differences, Ransford and Miller noted that in most previous research on stratification, socioeconomic status, ethnicity/race and gender are somewhat separate hierarchies, each affecting the distribution of power, privilege and prestige. . . . More accurate predictions and a fuller theoretical understanding often result from a consideration of the intersections or joint effects of SES [socioeconomic status], race and sex. These intersections of status positions represent unique social spaces within which persons construct explanations of reality. (46) *Direct all correspondence to Seth Ovadia,
