[9]Russell Fazio, an Ohio State psychology professor who has studied interracial roommates there and at Indiana University, discovered an intriguing academic effect. In a study analyzing data on thousands of Ohio State freshmen who lived in dorms, [10]he found that black freshmen who came to college with high standardized test scores earned better grades if they had a white roommate—even if the roommate’s test scores were low. The roommate’s race had no effect on the grades of white students or low-scoring black students. Perhaps, the study speculated, having a white roommate helps academically prepared black students adjust to a predominantly white university.
    [11]That same study found that randomly assigned interracial roommates at Ohio State broke up before the end of the quarter about twice as often as same-race roommates.
    Because interracial roommate relationships are often problematic, Dr. Fazio said, many students would like to move out, but university housing policies may make it hard to leave.
    "At Indiana University, where housing was not so tight, more interracial roommates split up," he said. "Here at Ohio State, where housing was tight, they were told to work it out. [12]The most interesting thing we found was that if the relationship managed to continue for just 10 weeks, we could see an improvement in racial attitudes."
    Dr. Fazio’s Indiana study found that three times as many randomly assigned interracial roommates were no longer living together at the end of the semester, compared with white roommates. The interracial roommates spent less time together, and had fewer joint activities than the white pairs.
