I've been asked to review a paper for a physics journal, and this is my first experience with being a reviewer.
Does anyone have any advice on being a good reviewer? Types of things to focus on, etc.?
Should I focus my critiques around the science alone, or is it ok to point out that the paper is poorly written (to the point that it obscures the science and impedes understanding.)
Some good comments here already. Reviewing a manuscript does not require you be to a subject expert, but it does require you to make an effort to understand what the authors are trying to say. I like to briefly summarize the goal(s) of the paper before making a few crucial comments:
1) What is new, and provide references if the results are already known.
2) Are the authors' claims validated by the results? Do the results agree with the discussion, or there other interpretations of the data that could lead to alternative outcomes?
3) Fact checks- is the data presented correctly, are there errors in derivations, do the figure captions match the data, was the experimental method faulty, etc.
4) Besides the authors, who else cares about this manuscript? Can the presented results be applied to other projects, or is it likely that nobody else cares?
5) Do the authors communicate clearly- are the graphs readable, the 'story' a clear logical progression, do they provide all needed background information, etc.? Note- some reviewers get hung up on this point and provide detailed lists of grammatical errors. Don't do that- you are not a copyeditor. A simple comment like "this manuscript would benefit from grammar and style editing" is sufficient.
Sometimes reviewers like to 'add on' extra things- suggesting additional experiments, for example. This is a gray area, and I would suggest refraining unless there is a compelling reason: unsubstantiated claims, lack of experimental controls, etc.
A reviewer has two goals. First, to ensure the science is accurately presented and discussed. Second, to help the authors make the paper better- pointing out strengths and weaknesses.
Other than that, try to be prompt with your review.
