…None of this means that we are doomed to discriminate by race. A 2001 study by Robert Kurzban of the University of Pennsylvania and colleagues in the Proceedings of the National Academy of Sciences found that race was much less prominent in how people categorized each other when individuals also shared some other prominent social characteristic, like membership on a team. If you set things up so that race conveys less important information than some other salient factor, then people pay less attention to race.
A second principle of psychology is the power of cooperation. When groups face a common threat or challenge, it tends to dissolve enmity and create a mind-set of “one for all, all for one.” Conversely, when groups are put into competition with each other, people readily shift into zero-sum thinking and hostility…
But as practiced in most of the top American universities, affirmative action also involves using different admissions standards for applicants of different races, which automatically creates differences in academic readiness and achievement. Although these gaps vary from college to college, studies have found that Asian students enter with combined math/verbal SAT scores on the order of 80 points higher than white students and 200 points higher than black students. A similar pattern occurs for high-school grades. These differences are large, and they matter: High-school grades and SAT scores predict later success as measured by college grades and graduation rates.
As a result of these disparate admissions standards, many students spend four years in a social environment where race conveys useful information about the academic capacity of their peers. People notice useful social cues, and one of the strongest causes of stereotypes is exposure to real group differences. If a school commits to doubling the number of black students, it will have to reach deeper into its pool of black applicants, admitting those with weaker qualifications, particularly if most other schools are doing the same thing. This is likely to make racial gaps larger, which would strengthen the negative stereotypes that students of color find when they arrive on campus.
And racial gaps in classroom performance create other problems. A 2013 study by the economist Peter Arcidiacono of Duke University found that students tend to befriend those who are similar to themselves in academic achievement. This is a big contributor to the patterns of racial and ethnic self-segregation visible on many campuses. If a school increases its affirmative-action efforts in ways that expand these gaps, it is likely to end up with more self-segregation and fewer cross-race friendships, and therefore with even stronger feelings of alienation among black students.
