Reviewing a journal article for free is common practice in academic publishing and is generally considered part of the responsibility of researchers within a given field. Peer review helps ensure the quality and integrity of scholarly work, and reviewers provide valuable feedback that improves the article.However, whether it's "fair" can depend on perspective. From the journal's side, they typically rely on volunteers because many academic journals, especially those that are open access, may have limited funding to compensate reviewers. From the reviewer's perspective, it may feel like unpaid labor, especially if the review process is time-consuming. In some fields, there are initiatives that offer recognition or small incentives (like discounts on future article submission fees), but compensation for reviews is not yet widespread. Some researchers argue that compensating peer reviewers might improve the quality of the review process by motivating reviewers to dedicate more time and effort.If you're doing this for the first time, it's important to weigh the value of contributing to your field, learning from the review process, and whether the effort is something you're comfortable with without direct compensation.
