Concerns are that opting for double-blind review might be seen as hiding a disadvantaged position. A survey conducted by Nature Publishing Group revealed that only 25% of submitting authors have opted for anonymity. Even though both reviewers and authors are blinded, the editors are not. In journals like Nature, editors conduct first screening of the papers and can reject them prior to peer review. Anecdotal evidence suggests that editors might feel inclined to recommend authors they met in the past, are familiar with, or who come from a well known institution.
