A diverse faculty and campus can be a laudable goal. But the point is to build academic communities that actually contain a wide variety of experiences and perspectives, not to wax self-congratulatory because you’ve met a set of ethnic quotas. The story of Elizabeth Warren, “woman of color,” represents a reductio ad absurdum of the latter tendency, which has been all too prevalent in elite universities — giving us affirmative-action programs that benefit West Indian immigrants more than the descendants of slaves, and faculties that include a wider range of skin tones than of political and religious views.

The irony is that Warren herself probably did make Harvard more diverse, since she grew up the daughter of a janitor in Oklahoma — not a typical background, to put it mildly, for Ivy League students and faculty today. But under the academy’s cramped definitions, it was her grandfather’s Cherokee cheekbones, not her blue-collar roots, that led to her citation as a supposed trailblazer.

That isn’t a serious approach to academic diversity, and in an emerging majority-minority America (already visible in the latest Census birth statistics) where almost everyone will be 1/8 something-or-other, it will be an increasingly untenable one as well.
