This is another good example of double-think from 1984. The Harvard admins believe in two mutually exclusive things: (1) that the minority students are obviously as capable as everyone else, and (2) that blind-exams where backgrounds of students aren't known would reveal undesired (i.e. "racist" in the newspeak) results. The art of double-think is watching your own mind and stopping it whenever it tries to connect the two opposites with logic.
