Peer review
Peer review of research articles prior to publishing has been common since the 18th century. Commonly reviewer comments are only revealed to the authors and reviewer identities kept anonymous. The rise of OA publishing has also given rise to experimentation in technologies and processes for peer review. Increasing transparency of peer review and quality control includes posting results to preprint servers, preregistration of studies, open publishing of peer reviews, open publishing of full datasets and analysis code, and other open science practices. It is proposed that increased transparency of academic quality control processes makes audit of the academic record easier. Additionally, the rise of OA megajournals has made it viable for their peer review to focus solely on methodology and results interpretation whilst ignoring novelty. Major criticisms of the influence of OA on peer review have included that if OA journals have incentives to publish as many articles as possible then peer review standards may fall (as aspect of predatory publishing), increased use of preprints may populate the academic corpus with un-reviewed junk and propaganda, and that reviewers may self-censor if their identity of open. Some advocates propose that readers will have increased skepticism of preprint studies - a traditional hallmark of scientific inquiry.
