Scientific papers aren't written for you, the layman. They are written specifically for scientists in that particular field. I'm a PhD student, and never have I read a paper with wording that I would describe as "convoluted."

What field are you in, because I wonder if this makes a difference? I'm in a highly interdisciplinary field, so perhaps that's part of the problem.
