The truth is that structural linguists like Gove and Fries are not scientists at all; they’re pollsters who misconstrue the importance of the “facts” they are recording. It isn’t scientific phenomena they’re observing and tabulating, but rather a set of human behaviors, and a lot of human behaviors are—to be blunt—moronic. Try, for instance, to imagine an “authoritative” ethics textbook whose principles were based on what most people actually do.
