How appropriate or common is it to recommend referees for your paper? I sometimes receive review requests that says the authors have recommended me, and I know them in person but I have no COI, so I do my best to objectively evaluate their paper. Also, I do suspect some labs might be recommending me as I always end up reviewing their papers (or maybe the editor thinks I am a good fit, I don't know).
When I submit however, I feel this is not very appropriate. I don't mind reviewing for others who recommended me but I don't recommend anyone because I don't think it is ethical, but I have been having problems with the reviewers simply not having adequate expertise on the field, though they are quite arrogant so in the end I receive reviews that are low-quality (and I mean this, they are not just mean reviews or anything, I mean reviews that are technically dead wrong that they don't get the scope, methodology not even what problem is being solved) How common is it to recommend referees for your paper? Am I missing something?
It's fairly common for journals to ask for reviewer recommendations. This is to help them get reviewers. Suggested reviewers make the editor's job easier, since they no longer need to work that hard to find people who can review the paper.
The downside isn't that it's unethical - I don't see why it would be - but rather that the authors are going to suggest their friends or even commit peer review fraud by nominating themselves. But that's something for the editor to worry about, not you.
Finally it's worth noting that not all reviewers you recommend will be invited to review your article - it's fairly common for journals to have a &quot;one recommended, one self-invited&quot; policy for example. In fact, it's possible none of the reviewers you recommend are invited.
