When to use "I" in a master's thesis A similar question exists here however I don't feel that answers my specific question. Other questions on this topic seem to explain why "we" is primarily used in academic writing, which I understand.

However, one part of my thesis is reviewing work I studied during the first half of my master's year, not the research I did. In this context I feel I should use "I did this..." or "I read..." etc. Not we, like I use in the research part.

So should I be using "I" when reviewing the subjects/topics I studied? As opposed to introducing the research I did in which case I use "We"
The answer is to ask your supervisor. Theirs is the only opinion that matters. It is unlikely that anyone except your supervisor and maybe your committee members will read your thesis.

I prefer "I" but that's irrelevant. I'm not your adviser.
