Wait! You Didn’t Use the Proper Lingo

Once introduced, a prescriptive rule about terminology in a particular profession or field of study is hard to eradicate, no matter how ridiculous. Steven Pinker writes in The Language Instinct:

The rules survive by the same dynamic that perpetuates ritual genital mutilations and college fraternity hazing: I had to go through it and am none the worse, so why should you have it any easier? Anyone daring to overturn a rule by example must always worry that readers will think he or she is ignorant of the rule, rather than challenging it. Since perspective rules are so psychologically unnatural that only those with access to the right schooling can abide by them, they serve as shibboleths, differentiating the elite from the rabble.
