Before we get our pitchforks out here, let's remember that Yale's percentage of Black students is 7.4%[1]. That's not exactly a gigantic portion. In fact Yale is on the lower end compared to Harvard's 14.3%[2] and MIT's 12% [3]. If Yale is truly discriminating in favor of Black and Hispanic students, well, they're not doing an excellent job of it.
