This question is a reformulation of a previous one that I deleted. I'll try to be more specific.
I'm a student in the field of International Relations, a sub branch of the Political Sciences. Reading works in the Social Sciences, I'm becoming progressively aware that convoluted language and pedantry are a significant problem in academic writing.
Sometimes the text is as hard as philosophy, whilst expressing common, everyday knowledge of the field.
Other times, language is okay, but the author is pedant.
Now, I wanted to know:
How often - if at all - professional academic reviewers face this issue?
If they do, will a thesis or paper ever face problems due to language usage?
Writers have personal tendencies. One may write in excess detail, repeat themselves, lose focus, etc.
That's not what I'm talking about.
I'm talking about affected, convoluted, artificial, forced and conceited use of language, as well as pedantry in its most evident forms.
As it turns out, I think I didn't make a good use of the "mannered" word. I edited the question to say "convoluted" instead.
I'm not a native speaker, so I think I failed to capture my intent here, anyways, a question was linked to this one that ultimately answers to much of my doubts.
