In the past few years I have received several revisions of articles that I have sent for publication in scientific journals. Some review documents contribute substantially to improving the manuscript even if it is not accepted for publication in that journal. However, I have observed that some reviewers are making assessments as "the owners of the truth". I think that criticism is important and constructive for the evolution of science. However, "scientific arrogance" seems to be spreading across the research community. Given this scenario, I would like to know your opinion on this matter. Are reviewers prepared to make evaluations in order to contribute to the authors? or Are the reviewers focusing on writing arrogant and destructive criticisms? Is the practice of academic kindness scarce? Is believing that there is only one way to find solutions something that consolidates the literature or limits the work of researchers? Let's talk about this.
