Peering into peer review: Good quality reviews of research articles require neither writing too much...

<jats:p>Abstract The value of scientific knowledge is highly dependent on the quality of the process used to produce it, namely, the quality of the peer-review process. This process is a pivotal part of science as it works both to legitimize and improve the work of the scientific community. In this context, the present study investigated the relationship between review time, length, and feedback quality of review reports in the peer-review process of research articles. For this purpose, the review time of 313 referee reports from three Chilean international journals were recorded. Feedback quality was determined estimating the rate of direct requests by the total number of comments in each report. Number of words was used to describe the average length in the sample. Results showed that average time and length have little variation across review reports, irrespective of their quality. Low quality reports tended to take longer to reach the editor, so neither time nor length were related to feedback quality. This suggests that referees mostly describe, criticize, or praise the content of the article instead of making useful and direct comments to help authors improve their manuscripts.</jats:p>
