Proofreading documents for orthography is a pain. I consider that I am decent at writing in my native language (on the grammar and orthography side), but proofreading for typos and whatnots is a time-consuming pain. I’d much prefer to have someone else do it for me, but it's a pain to bother other people with it. Also, when I read students’ work, in some cases it requires two iterations (because it's hard to focus on the science when the spelling is… suboptimal).
So, given that a professional proofreader would be much more efficient at this job than me, leaving me more time to review the scientific content or otherwise actually do research, the logical conclusion is that I should hire one. This would work either for my own writing or for
I know some people actually do that (and also buy more extensive services) for grant writing. However, I wonder: is it ethical to hire a proofreader for theses and academic articles?
