Double-blind peer review is an evaluation process used by most professional journals to ensure research meets basic field standards before entering the published literature. In this system, researchers submit a manuscript to an editor, who forwards it to expert reviewers; the process is 'double-blind' because the identities of both the researchers and the reviewers are kept strictly concealed from one another. Reviewers provide critical feedback and publication recommendations, which the editor uses to accept, reject, or request revisions for the manuscript.
