I totally agree, @theloniusmonk. I didn’t mean to imply that only HYP have extraordinary kids in terms of intellect. Percentages are no doubt even higher than 5% at MIT and CalTech, for instance, but all T50 schools reliably have their shares. Especially state flagships, because financial considerations really limit the ability of privates to attract all the best and brightest (say, the >+3sd kids - maybe 4,000-6,000 kids total in the entire domestic applicant pool?). Anyway, no school would want to get too lopsided with “top brains” for obvious reasons.
