What is the role of external reviewers in the peer-review process?

The role of external reviewers in the peer-review process is primarily to evaluate manuscripts for possible publication. They serve as experts in the field related to the manuscript's topic, providing an independent assessment of the quality, originality, and significance of the research presented. Their evaluations help ensure that the work meets the necessary standards of academic rigor and contributes meaningfully to the existing body of knowledge.

External reviewers critically analyze various aspects of the manuscript, including the methodology, results, discussion, and overall clarity of the writing. Their feedback aids editors in making informed decisions about whether to accept, revise, or reject a submission, ultimately enhancing the quality of published research.

In contrast, external reviewers do not typically provide editing services, conduct the research themselves, or write comments in the way that directly influences the article’s content without evaluation. Their primary function is to provide an objective critique, which is vital in maintaining the integrity of the scientific publishing process.
