Regarding the gender imbalance, I think it would be interesting to compare with the gender numbers from the authors or researchers in general. Are 25% female reviewers an over- or underrepresentation of the research community in the given field?
Hi Andrea! We did think about this - it's in part why we haven't set a target of boosting the participation of, for example, female reviewers. In some fields, this could result in disproportionate distribution of workload where a small number of female researchers receive many review requests. I'll see what kind of data we can collect over the next twelve months and maybe have something that looks at these questions in more detail next year!
