The academic establishment is known to use very long official terms. It is also known to claim things on the lines of "dogma X has not been disproven, it has only been modified" and to say that "this theory is not the same theory as it was", forcing people to use even longer explanations of what they mean. This serves the purpose of forcing critics to choose between a technically correct mastodont-longeur that puts readers/listeners off/makes them lose track of the actual information content, and a concise explanation that the academic establishment can call "ignorant" or "crackpot".
