Bs Math Quotes

You can tell if a discipline is BS if the degree depends severely on the prestige of the school granting it. I remember when I applied to MBA programs being told that anything outside the top ten or twenty would be a waste of time. On the other hand a degree in mathematics is much less dependent on the school (conditional on being above a certain level, so the heuristic would apply to the difference between top ten and top two thousand schools). The same applies to research papers. In math and physics, a result posted on the repository site arXiv (with a minimum hurdle) is fine. In low-quality fields like academic finance (where papers are usually some form of complicated storytelling), the “prestige” of the journal is the sole criterion.

A group of researchers asked ninety-nine college freshmen and sophomores to think back a few years and recall the grades they had received for high school classes in math, science, history, foreign language study, and English.44 The students had no incentive to lie because they were told that their recollections would be checked against their high school registrars’ records, and indeed all signed forms giving their permission. Altogether, the researchers checked on the students’ memories of 3,220 grades. A funny thing happened. You’d think that the handful of years that had passed would have had a big effect on the students’ grade recall, but they didn’t. The intervening years didn’t seem to affect the students’ memories very much at all—they remembered their grades from their freshman, sophomore, junior, and senior years all with the same accuracy, about 70 percent. And yet there were memory holes. What made the students forget? It was not the haze of years but the haze of poor performance: their accuracy of recall declined steadily from 89 percent for A’s to 64 percent for B’s, 51 percent for C’s, and 29 percent for D’s. So if you are ever depressed over being given a bad evaluation, cheer up. Chances are, if you just wait long enough, it’ll improve.
