 Scholars began referring to this theory as "mismatch." It's the idea that affirmative action can harm those it's supposed to help by placing them at schools in which they fall below the median level of ability and therefore have a tough time. As a consequence, the argument goes, these students suffer learningwise and, later, careerwise. To be clear, mismatch theory does not allege that minority students should not attend elite universities. Far from it. But it does say that students -- minority or otherwise -- do not automatically benefit from attending a school that they enter with academic qualifications well below the median level of their classmates.
