Sometimes three is just an inherent smarty-pants style to writing academic papers. I lose track of how many times I instinctively try to write something like "utilize" or "make use of" when a simple "use" will work.
But, at least in scientific writing, you use complicated language in order to be absolutely precise about your method and findings (as opposed in particular to scientific journalism...). As an example, I work in the field of direct experimental searches for evidence of interactions between particle dark matter and nuclei. That's a huge mouthful, but every single word in that phrase carries distinct meaning, and if you take any of them out, it is not a correct description of what I do, and may refer to another field entirely.
Now take that kind of precision and discuss an experimental result. "We find that, at 90% confidence level, there is no statistically significant evidence for X". Again, it sounds like buzzwords and jargon, but there is simply no way to turn that statement into "common" English.
