Even the driest type of academic writing (in my opinion, a publication) has tone, that is, subtle cues that give hints about the author. In all of your writing (even email), beware of your tone. Strive for a tone that is authoritative (but not over-stating or boastful), ethical (without being preachy), and concerned (without being emotional). Be respectful of all persons (your reader, those you cite, the people in your study). Be honest and acknowledge what you do not know (such as the full explanation for strange results).
Beware vague or colloquial phrases which lack clarity and might make you sound “junior”:
• Just to name a few
• In the here and now
• Have come to discover
• Speaks volumes
• Heavy lifting
Limit overly emotional or loaded terms unless you have good reason for use:
Aim for clarity. Have a point of view. Give your reader every reason to respect you and attend to your writing.
