Use the first person when writing about your own perspective. Do not use the royal we. The APA Manual states:
To avoid ambiguity in attribution, use the first person rather than the third person when describing the work you did as part of your research and when expressing your own views. If you are writing a paper by yourself, use the pronoun “I”; do not use the pronoun “we” to refer to yourself if you do not have coauthors. If you are writing a paper with coauthors, use the pronoun “we.” Do not refer to yourself or your coauthors in the third person as “the author(s)” or “the researcher(s).” (APA, 2020, p. 120)
