Jaana Juvonen, a professor of psychology at UCLA and the lead author of the study, noted that “when ethnic groups are of relatively equal size, there may be more of a balance of power. One or more large ethnic groups will be less likely to exert their influence over one or more small ethnic groups.”
The study also found that when students attended classes that were significantly less diverse than their school overall, the benefits of diversity disappeared.
The full study, “When and How Do Students Benefit From Ethnic Diversity in Middle School?” was published on the website of the journal Child Development. It may be accessed here.
