publications - Soliciting pre-submission manuscript comments from people who could later be peer reviewers

Before submitting a manuscript to a journal, it is fairly common at least in my field (psychology) to circulate the manuscript in a limited way to a small number of people who are experts in the area and/or who would be willing and able to provide useful comments, for the purpose of soliciting their feedback and suggestions for improving the manuscript before submitting it for formal peer review.

However it seems that this could lead to a tricky situation if the editor of the journal ends up asking some of those same people who provided feedback to serve as reviewers for the paper, since they will have already read the paper and in a sense "reviewed" it one time already.

So I have two questions about this:

1. From the perspective of a person who has been asked by the authors to provide comments, and then later asked by a journal editor to review that same paper for publication: what is your policy, or your perception of the common policy, for what do to here? Do you decline to review the paper because you've already seen it? Do you agree to review the paper, but perhaps provide many of the same comments verbatim as before (at least for the parts of the paper that were not changed), and perhaps let the editor know that you've read it before? Or do you see your prior reading of the paper as totally irrelevant and just approach the review fresh and as normal?


2. From the strategic perspective of the authors of the paper, is it better to ask for comments from people who you know are likely to be asked later to review the paper? Or is it better to avoid sending the paper to these people, and instead send it to people who are not as likely to be asked to review the paper but could still provide useful feedback?

Answer

There are two aspects to this question: what should happen and what actually happens. Soliciting comments on a manuscript is of course perfectly fine and a useful endeavour. As you state problems may arise if persons commenting on the manuscript is asked to review it. Such a person should simply decline to review the paper when requested. It is thus possible that such a person reviews the paper anyway but then the problem is between the reviewer and the editor, that is beyond your reach. What you can do to simplify for an editor is to list persons who have commented on the manuscript. It will then be up to the editor to decide what becomes a breach of objectivity.

If your topic is narrow enough that the number of possible reviewers are limited, you need to consider if you "use up" potential reviewers in the process. Again, I think being open about who has commented on the paper in your correspondence should allow the editor to find good reviewers. Just because you avoid soliciting someone's opinion does not mean the editor will ask that person for a review so assessing such effects is difficult and generalized answers of little use. Knowing the field and potential problems is the only way to assess pros and cons.
