Earlier quoted context omitted.
It seems like having all those arbitrary requirements is good for nothing but gatekeeping higher education. Why not have those requirements publicly known and not unnecessarily complicated so that everyone can submit info?
They are publicly known. But I would say most paper requirements are "necessarily complicated", simply because science is hard. Writing a scientific paper requires both solid science (both good results and good scientific practices) and solid writing skills to convey an important idea in a clear and precise way. Mastering both aspects requires time and effort. An academic author is a person who made a job out of it.…
The only person who would read a journal paper and say that the the author has good writing skills is another academic.
No one outside of the research community would look at a typical journal paper and claim that the writing skills demonstrated are "solid".
Asimov once wrote about his own dilemma when he was ready to write up his PhD thesis: He had spent over a decade up to that point honing his writing skills, that he truly did not know if he had it in him to write as poorly as is needed for academia.
From my experience in academia:
1. Far too many people still prefer the passive voice over the active voice.
2. Far too many prefer to refer to themselves in the 3rd person.
3. Trying to explain how I arrived at an expression that took me weeks to derive was discounted and I was told to remove it by my advisor: As long as I wrote the starting point "any competent researcher should be able to derive it" (hint, probably half cannot).
4. Writing any background so that someone who is not already an expert can understand was strictly forbidden - always guaranteed to get a complaint by some reviewer or another. If it appears in a textbook or in another paper, do not think about including it in your paper. As a result, the only people who can understand your paper fully are those who have happened to read the same textbooks and papers you have. A poor new graduate student may need to look through several papers and a book or two to get the background needed for one section of your paper, even though you could have explained it all in a page or two. But nope - they may have to go scan over a hundred pages of material to have an idea.
Just a few I remember off the top of my head. Results may vary with discipline.
