“…In preparing the material for this session, I realized that I was encoding into routine a series of practices that I look for in the reviews we receive at Earth Surface Processes and Landforms (ESPL). In looking across reviewing practices more widely, across a range of science journals, I detected a common theme: a tendency to see that reviewing is something that we typically learn by osmosis; and a number of journals have flagged the need to make sure that reviewers (as well as authors) receive proper training (Isaacs, ; Shugan, ; Moizer, ). Given the importance of publication to authors, the time that authors invest in preparing their manuscripts, and the critical role that reviewers play in defining the corpus of knowledge that constitutes our discipline, drifting into reviewing practice by osmosis carries risks: that our submitted manuscripts, and their authors, might not get the attention that they deserve; and, most seriously, that reviewing practices acquired through experience are not subject to the proper scrutiny and formation that they require.…”
