Passive vs. Active Voice

[AbbieBristol 0]

Hi folks,

I'm working on writing a grant and I'm curious if people typically write in passive voice ("This species was known to be present since...") or if active voice is preferred ("We knew this species was present since...")

I know scientific papers have historically been passive voice, but are shifting to be more active, and I was curious if grant writing is in the same boat.

Thanks!
