What guarantees the credibility of peer-reviewed articles?

The credibility of peer-reviewed articles is primarily guaranteed by the fact that they are evaluated by professors and experts in the respective field before publication. This rigorous process involves a thorough assessment of the research methodology, findings, and overall contribution to the field, ensuring that the article meets high academic standards. The peer review process acts as a quality control mechanism, filtering out studies that do not adhere to the necessary level of accuracy, reliability, and scholarly rigor.

Options like being widely cited or having high accessibility online can contribute to the visibility or recognition of an article but do not inherently ensure its credibility. The frequency of publication, while important in academic discourse, does not relate directly to the validation of the research presented. It is the expert evaluation that is critical in establishing whether an article can be trusted in the academic community.
