Another thing to consider: Hogg is highly visible and, if he doesn't reconsider and does indeed go to Harvard, he will be very clearly stamped as the weakest white student on campus, and this by a wide margin. If I were him, I'd not want to walk that path. He may be too full of himself to think this through clearly. No one will laugh at him publicly. That would be un-PC. But they will all laugh at him behind his back.
Addendum: we should also not dump on young Hogg unduly. The average SAT score this year was 1068. Hogg is in the 85th percentile among all U.S. college bound seniors. He would be a fine candidate at a typical, reasonably good flagship state university or non-elite private school. I hope his parents have the sense to steer him in a direction that allows him to flourish, as opposed to setting him up for frustration and failure. If they’re really smart, they’ll steer him to a school where he might actually be exposed to differing perspectives and get a real education.
