Diversity Makes You Brighter; New York Times, 12/9/15

Sheen S. Levine and David Stark, New York Times; Diversity Makes You Brighter:

"Our findings suggest that racial and ethnic diversity matter for learning, the core purpose of a university. Increasing diversity is not only a way to let the historically disadvantaged into college, but also to promote sharper thinking for everyone.

When it comes to diversity in the lecture halls themselves, universities can do much better. A commendable internal study by the University of Texas at Austin showed zero or just one African-American student in 90 percent of its typical undergraduate classrooms. Imagine how much students might be getting wrong, how much they are conforming to comfortable ideas and ultimately how much they could be underperforming because of this.

Ethnic diversity is like fresh air: It benefits everybody who experiences it. By disrupting conformity it produces a public good. To step back from the goal of diverse classrooms would deprive all students, regardless of their racial or ethnic background, of the opportunity to benefit from the improved cognitive performance that diversity promotes."
