Academic writing is all about audience. The primary publication is something akin to a proof, and precise language is important there. I'll be damned in most naming conventions aren't terrible, but if I say "white blood cell", that means one thing to the layman, but to the academic, that means one of several things. More often it's a page-limit that removes explanatory sentences and crunches phrases down into polysyllables. At a certain point, you have to pick what to define and what not to. I would assume a scientific audience knows molecular orbital theory but maybe not Raman scattering. But then again, I'm not going to re-list the rules of quantum mechanics if I'm writing to physicists and I consider that to be common knowledge among them. Still a good read and shared, the "Curse of Knowledge" is definitely one I encounter a lot.People often tell me that academics have no choice but to write badly because the gatekeepers of journals and university presses insist on ponderous language as proof of one’s seriousness,
