Journal editors and peer reviewers are significantly more likely to accept work from authors whose backgrounds match their own, according to a study that sheds new light on gender and minority biases within academic publishing.

Given the over-representation of men and academics from North America and Europe within these ¡°gatekeeper¡± roles, the finding ¨C based on analysis of peer review outcomes of 23,873 initial submissions and 7,192 full submissions to the biosciences journal?eLife?between 2012 and 2017 ¨C goes some way towards explaining the under-representation of women and researchers from the rest of the world in scientific periodicals.

For the new study, published as a working paper on the preprint repository?, researchers from universities in the US, Netherlands, UK and Canada sought to determine the gender balance and nationality of editors and peer reviewers and last-named authors.

Gatekeepers were found to be more favourable towards manuscripts from authors of the same gender and nationality as them.

The acceptance rate for manuscripts with male last authors was significantly higher than that?for female last authors ¨C an inequality?that was greatest when the team of reviewers was all-male, they found.

Manuscripts submitted to eLife were 1.8 per cent more likely to be published if they had male corresponding authors, and papers that had female lead authors were published at 88.3 per cent of the rate of those with male lead authors.

Similarly, manuscripts submitted by lead authors from China were accepted at only 22 per cent of the rate of manuscripts submitted by a lead author from the US.

Mixed-gender gatekeeper teams led to more equitable peer review outcomes, the authors note. All-female reviewer teams also displayed a higher acceptance rate for female authors,?although cases of all-female teams were rare, meaning that the sample was too small to draw meaningful conclusions.

¡°±õ²Ô³¦°ù±ð²¹²õ¾±²Ô²µ?eLife¡¯s representation of women and scientists from a more diverse set of nations among editors may lead to a more diverse reviewer pool and a more equitable peer review process,¡± the researchers conclude.

Common oversights that can lead to lack of diversity in publishing, they say, include a tendency for editors to invite peer reviewers from their own professional networks ¨C causing the editors, who are most often men from scientifically advanced countries, to inadvertently exclude certain groups.

While the study¡¯s authors highlight that double-blind peer review processes are ¡°generally viewed positively by the scientific community¡± as a way of reducing personal biases, the approach is not widely used in biosciences, and previous experiments found authors ¡°rarely opted in when offered¡±.

Earlier this year,?eLife?announced a new trial in which it committed to publishing all articles it accepted for peer review, on the condition that authors agreed to have all reviewer reports and decisions published transparently alongside the paper. The experiment was seen as a way of putting more power in the hands of authors by removing the gatekeeping role played by peer reviewers.
