Journal editors are constantly on the lookout for good peer reviewers (also referred to as ‘referees’). The qualities of a good peer reviewer include the right qualifications and expertise to effectively review a manuscript, the ability to meet deadlines, and a lack of potential conflicts of interest with the manuscript’s authors and their research. Another key factor in the selection is to meet the mandate of diversity, equity and inclusion (DEI). Accordingly, reviewer selection also needs to be diverse enough in terms of gender, geographical location and career stage.
