Many choice observations found here. I'm very keen on clarity, a desire sparked in me years ago when @klenbl00@ pointed out the deficit between face-to-face communication and communication over Facebook messages. I've been striving to be a clearer communicator ever since.
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.
