A good excuse to talk about conflicts of interest. You should not review, edit or referee a paper if one of the authors is
- a relative and/or someone you are romantically involved with, or
- a member at your institution.
The NSF has more stringent restrictions for reviewing proposals. If we used these restrictions for paper reviews, like no close collaborators or no former students/advisor, there might not be any one left to properly evaluate the paper. If the restrictions (1) and (2) don't apply to you, you should state any potential unknown conflicts but feel free to say whether the paper soars like an eagle or gobbles like a complete turkey.
Speaking of turkey–Have a great Thanksgiving everyone!
