What Does “Peer-Reviewed” Mean?

Peer-review is a type of quality control.  It means that an article has been reviewed by other scholars or experts in the field (peers) before being published.  Other terms for peer-reviewed are “refereed,” “scholarly, or “academic.”

These peers have reviewed the article for methodological errors, flaws in judgment, potential bias, originality, etc. Only after an article has gone through this rigorous review is it published in a journal with other peer-reviewed articles. In other words, a peer-reviewed article should be of high-quality.

If a journal is peer-reviewed, the articles in it are too.  However, editorials, commentary, letters to the editor and book reviews are not peer-reviewed, even if you find them in a peer-reviewed journal.  Newspaper or magazine articles can be useful for finding background information during the research process, but they are not peer-reviewed. Society or organization newsletters and blogposts are not peer-reviewed.
