Use of first person in a PhD Thesis
My personal opinion also is that third person is very bad writing style, since it offloads responsibility for the presented results to some external entity. As if it wasn’t me who made the stupid decision to push that other guy from the cliff, but the guy was (somehow) pushed from the cliff. In my opinion, “we” solves that problem only a little bit, because now the writer admits a bit of responsibility for the act, but still dilutes it by taking into the game somebody else (either the reader, or the abstract research community). Saying “I did this and that and by doing it I personally found this and that” for me is fully taking responsibility for my results ..
