One of the least enjoyable tasks of a journal editor is to nag referees to send reports.  Many things have been tried to induce timeliness and responsiveness.  We give deadlines.  We allow referees to specify their own deadlines.  We use automated nag-mails.  We even allow referees to opt-in to automated nag-mails (they do and then still ignore them.)

When time has dragged on and a referee is not responding it is typical to send a message saying something like “please let me know if you still plan to provide a report, otherwise i will try to do without it.”  These are usually ignored.

A few years ago I tried something new and every time since then it has gotten an almost immediate response, even from referees who have ignored multiple previous nudges.  I have suggested it to other editors I know and it works for them too. I have an intuition for why it works (and that’s why I tried it in the first place) but I can’t quite articulate it, perhaps you have ideas.  Here is the clinching message:

Dear X

I would like to respond soon to the authors but it would help me a lot if I could have your report.  I realize that you are very busy, so if you think you will be able to send me a report within the next week, then please let me know.  If you don’t think you will be able to send a report, then there is no need to respond to this message.
