In the traditional peer review process, what is true about single-blind review?

In the traditional peer review process, a single-blind review is characterized by the reviewer knowing the identity of the author, while the author does not know the identity of the reviewer. This means that the reviewer can see who authored the submission they are evaluating, which can influence the review process in various ways. It allows reviewers to consider the qualifications and background of the author, potentially leading to more informed critiques based on the author’s previous work and reputation.

The other choices describe different aspects of peer review processes. For instance, revealing the identity of the reviewer to the author does not apply in a single-blind system; that is more characteristic of an open review process. Concealing both identities is known as a double-blind review, where neither the author nor the reviewer knows each other's identities, aiming to eliminate bias based on known identities. Hence, the definition of single-blind review aligns with the correct choice, which reflects the key aspect of the process.
