When writing scientific research proposals I have been advised to try and stick to active voice because passive tends to sound indirect and to imply doubt. However, when writing in active voice, I find it difficult to not use personal pronouns. Does anyone have any tips for maintaining active voice without using personal pronouns?
Well, if you're that bothered about avoiding personal pronouns, you can always say "The author", "The researcher" etc. It's really a matter of preference; not all scientists think there's anything terribly wrong with good old-fashioned words like "I" and "we"...
You may also want to see if you can actually find a scientific study attesting to the perceived indirectness or doubt of the passive.
