Scott Jaschik's article, "New Look at the Impact of Diversity," invites the reader to explore the dynamics of racial diversity on the college environment, discussing the findings of a longitudinal study conducted at UCLA (University of California, Los Angeles) that provides empirical evidence that documents student's racial attitudes. In a longitudinal study at UCLA, Sidanius and associates found that exposure to other races and ethnicities has a positive impact on the racial attitudes of students (Sidanius, Levin, Van Laar, & Sears, 2008). Their research expands a growing body of literature (AASCU& NASULGC, 2005; Harper & Hurtado, 2007; Milem, Chang, & Antonio, 2005) concerned with identifying educational benefits associated with a diverse college campus. On the other hand, findings of this study also revealed that membership in groups that are defined largely by race and ethnicity (e.g., Black student union, Latino student association, etc.), and in fraternities and sororities whose membership is dominated by one racial group, has a negative impact on intergroup racial attitudes. This commentary explores the implications of these two findings. A list of references and suggested readings is provided.
