Those who criticize academics for their writing style might want to compare academic writing with that of the "average person". The truth is most people don't write all that well, whether they are academics or not.
Furthermore, that's fairly typical of nearly ever field. Most people don't sing or play music all that well, most people don't do auto mechanics all that well, etc, etc, etc. Academia merely tries to squeeze a whole lot of bad and mediocre writers into a more or less traditional and uniform style.
All of that is to say nothing about the fact that most people do not read at the university level any way, and have difficulty comprehending even clearly explained, simple ideas, if those ideas are unfamiliar to them.
Exactly. I think it also depends on the field. It seems as no surprise that the softer fields are gong to be the one with unnecessary jargon. . . Literature, philosophy, art criticism, etc. I can see why academics in those fields would have something to prove or obfuscate.
If there is "jargon" is harder sciences, it is often going to be more necessary to demonstrate methodology, results, and the discussion sections.
My wife has published some 30+ papers in academic journals in the fields of women's health and cancer. I often read and provide feedback.
Ten years ago, I would have been lost . . . But now it's easy to understand papers in her field, and many other fields as long as the mathematics aren't too challenging. There's a surpising consistency in the the academic language in her field. Just because you aren't educated in that, or any, particular field does not automatically mean the jargon is excessive or unnecessary. You just don't understand it.
P.S. I'm going to venture that 62% of RF users don't have the academic vocabulary to understand the writing of scientific publications, and 17% are probably eating potato chips right now.
Apparently, it's okay now to just completely make up numbers to prove a point.
