I am so happy that I have brought myself to tell my supervisors that I DON’T want them to proofread my writings. I want them to focus on my contents instead of spending time on correcting grammar, wordings, or paragraph structures. I told them I would get some native speaker to proofread my work when it would be reviewed externally (e.g. in annual reviews) , but I wouldn’t be able to do that every time I sent things to my supervisors. They all agreed to this.
I asked this because during my master’s study I got two kinds of markers: one solely focus on my contents; the other suggesting alternative wordings for every phrases they deemed inappropriate. I didn’t felt supported by the latter ones. I mean, I do know that poor writing leads to poor thinking, and I will relentlessly work on improve my own writing. It’s just that some works are better done by proofreaders or AIs, and some by academic experts in the field.
