Many of the most draconian measures implemented in the first couple weeks of the new Trump Administration have been justified as emergency actions to root out D.E.I.—diversity, equity, and inclusion—including the freeze (currently rescinded) of trillions of dollars in federal grants. The tragic plane crash in Washington, the President baselessly suggested, might also be the result of D.E.I. Typically, D.E.I. describes policies at large companies or institutions to encourage more diverse workplaces. In the Administration’s rhetoric, D.E.I. is discrimination pure and simple, and the root of much of what ails the nation. “D.E.I. is the boogeyman for anything,” Jelani Cobb tells David Remnick. Cobb is a longtime staff writer, and the dean of Columbia University’s Graduate School of Journalism. “If there’s a terrible tragedy . . . if there is something going wrong in any part of your life, if there are fires happening in California, then you can bet that, somehow, another D.E.I. is there.” Although affirmative-action policies in university admissions were found unconstitutional by the Supreme Court, D.E.I. describes a broad array of actions without a specific definition. “It’s that malleability,” Cobb reflects, that makes D.E.I. a useful target, “one source that you can use to blame every single failing or shortcoming or difficulty in life on.”
