An issue that came up in the previous thread, one which I’ve discussed several times with others, is whether the editor should share the report from referee 1 with referee 2. (There are other issues related to sharing reports with the author, but I’ll save those for another thread.)
I myself have never directly seen the report from the second referee when I referee a paper. But occasionally the author quotes from that report extensively in the reply to referees that I receive in a revise and resubmit. (Sherri Irvin reports in the previous thread that the Journal of Aesthetics and Art Criticism informs referees of the editor’s decision and includes both referee reports in that email.)
Beside simple curiosity, it seems the main benefit of sharing referee 1’s report with referee 2 is to help referee 2: it serves as a sort of calibration for referee 2 on her report. At any rate, that’s the benefit I’ve heard discussed. (There may also be the potential complication that, after reading a report from referee 2, referee 1 might change her mind, raising all sorts of issues about what an editor ought to do if that happens.)
It seems to me referees have a reasonable expectation that their reports are not being shared outside the editorial team and the author. But that’s simple to change: either inform them otherwise before they agree to referee, or ask their permission and share the report with the other referee only if permission is granted.
So what issues do we see with sharing referee reports with other referees for the same paper?
