subject is from the truth, the more snobbish he or she is likely to be. In this amusing scheme, mathematicians and physicists care least about clothes, wine, food, and other such potentially snobbish refinements, while people in English, history, and modern language departments, whose subjects put them so much further from the solid ground of unarguable truths, care a great deal, since their reputation for being cultivated is really all they have going for them. Quite nuts, or so it might seem, if lots of evidence didn’t support it.
