The only way I’ve heard the term “peer review” used is to make scientific study reports, and often the data and methodology used in the study, available to other researchers in the relevant fields, so that they can apply rigorous scientific principles and methods proven to minimize bias to an examination of the work. The purpose of this is to determine where the research is weak, where it is strong, and suggest ways to improve the objectivity of the research and/or the reporting of the research. Peer review is about eliminating bias and improving the objective accuracy of research and reporting on that research.
Peer review is therefore the opposite of bullying people to force them to have your beliefs, or to produce particular results desired by the reviewers, which seems to be the subject of the article linked above.
