Generally it is considered to be "good practice" to write reports in the third person passive voice for a wide array of academic writing. It is even a requirement of publication in several journals.
However, I have been unable to find any sort of information for "why" this is the way it is. I can't find any studies on the effect of reports written in the passive vs active tenses nor the effect of 3rd vs 1st person.
Could anyone shed any light on why this is the way it is?
