I have been peer reviewing scholarly manuscripts for more than 10 years, and I am always concerned that the quality of my reviews might be impacted by the fact that my name is made public to authors or other people, instead of the typical scenario in which authors are blinded to the reviewers' identity. This is becoming more and more commonplace in the open access era.
For instance, some journals let authors but not readers know the name of the reviewers. One example is the British Medical Journal (BMJ). Specifically, the BMJ website clearly states:
"For research papers, The BMJ has fully open peer review. This means that every accepted research paper submitted from September 2014 onwards will have its prepublication history posted alongside it on thebmj.com. This prepublication history comprises all previous versions of the manuscript, the study protocol, the report from the manuscript committee meeting, the reviewers’ signed comments, and the authors’ responses to all the comments from reviewers and editors."
A similar approach, in which the peer reviewer's identity can be disclosed to authors on a voluntary basis, is followed by journals such as PLOS ONE ("Will authors know who is reviewing their manuscript? Reviewers’ identities are anonymous unless a reviewer indicates otherwise"). Other journals, instead let everybody, even readers, know their identity (e.g. World Journal of Meta-Analysis).
I favor the approach followed by the Baishideng Publishing Group (fully open model), but I am wondering what is the opinion and insight of the ACADEMIA community.
