In truth, the entire weird and crufty vocabulary is simply a common set of placeholders that makes it easier to grasp research, because the in-group learns to understand them as such.
It is also true that science literature contains a lot of jargon that encodes important information. But that doesn't excuse the fact that a lot of scientific writing could be improved substantially, even if the only audience were experts in the same field.
As an educated lay person who dips into scientific papers occasionally I completely agree with this. And now I have a nice phrase I can remember next time I read a scientific paper and think "why does science hate me?".
But first you need something good to write about, and a lot of papers fall short at that point. It doesn't matter how well it is written at that point (getting the "this is well written, but not interesting" rejection is painful but usually obvious).
"don't write like you have a pole up your ass."
It contained formatting rules. The text must be double spaced size 11 font, The table of contents must be laid out in this specific way, tables and figures have to be included and referenced in this particular fashion and so on.
It also imposed rigid restrictions on language usage and writing style it basically emphasized writing short sentences. No adverbs. Avoid passive voice, Write everything in first person tense and so on.
I asked my housemate who studied creative writing to proof read my thesis. He commented on how sterile and cold the whole things felt compared to the more florid prose he was used to.
So the way scientific papers read is very much by design.
