In a Washington Post article written by New York University’s Jonathan Zimmerman, students can understand diversity better if they have a roommate of a different race.  The research supporting this is mixed, with one recent study “published in the Harvard Business Review, point[ing] out that efforts to increase racial harmony “can backfire,” leading to “increased hostility rather than less.”” Despite this there is evidence to support Zimmerman, for example, a “recent research by Dartmouth College economist Bruce Sacerdote showed that interracial freshmen roommate pairs were more likely to interact with members of different races than were freshmen who roomed with someone of the same race.”
