“…More generally, papers with only male authors were more abundant than would be expected if collaborations were assembled without consideration of gender, though this pattern was much stronger in the larger published papers dataset (Figure 4) than in the smaller submitted papers dataset ( Figure A3). These results are consistent with similar patterns observed in other fields-that women coauthor papers with other women, and men with other men, more often than would be expected if collaborations were assembled without regard for gender (Bonham & Stefan, 2017;Fishman et al, 2017;González-Alvarez, 2017;Long, Leszczynski, Thompson, Wasan, & Calderwood, 2015;McCann, Ebert, Timmins, & Thompson, 2017;Shah, Huang, Ying, Pietrobon, & O'Brien, 2013). Similar associative gender sorting has been reported for academic mentor-mentee relationships (e.g., Davis, Jacobsen, & Ryan, 2015).…”
