The Philosophy Student Writer’s Manual (2nd Edition) is just one of the many sources asserting, in as many words:
Philosophy majors score significantly higher than all other humanities and social science majors on standardized tests for admission to graduate and professional study. This includes tests for business, medical, and law school. Majoring in philosophy is one of the wisest investments you can make in your education.
But isn’t that a rank fallacy? Perhaps the test scores of those who survive a philosophy degree are higher because philosophy is a much harder major than underwater basket weaving. Lewis & Clark University’s repetition of the same claim seems to inadvertently support this explanation: “the only fields that score higher mean scores on the combined Verbal, Quantitative, and Analytical sections of the GRE are (in rank order) Physics and Astronomy, Mathematical Sciences, Materials Engineering, and Chemical Engineering.” Those are some of the few majors more difficult (in my opinion) than philosophy.
