Trends in Scientific Collaboration Between Men and Women Following the #MeToo Movement

The #MeToo movement raised global awareness about harassment in the workplace. Concerns were raised, however, that the movement may have unintendedly harmed women in academia by decreasing collaboration invitations from men in senior positions, who might be more reluctant to collaborate.

To analyze whether collaborations between first author women and last author men decreased after the #MeToo movement.

Retrospective observational study.

Names of first and last authors of 122,450 US review articles from the PubMed database published between 2014 and 2020.

Change in the proportion of review articles with a first author woman and a last author man following the peak of the #MeToo movement in October 2017. Additionally, among review articles with a last author man, trends of women first authorship in the USA and Europe (control group) were compared.

We analyzed 122,450 review articles with first and last authors from US institutions. Of 85,015 articles by a man last author, 37.5% (31,902) had a woman first author. In contrast, when the last author was a woman, the first author was also a woman in 53.6% of articles (20,078) (p<0.001 for difference). Among review articles with a last author man, there was no change in the proportion of articles with a woman first author before versus after the peak of the #MeToo movement (e.g., p=0.13 for difference between the 12 months following October 2017 compared to the pre-#Me-too period). Among European institutions, of 72,036 articles by a man last author, 43.4% (31,294) had a woman first author, higher than the proportion observed in the USA. Trends in collaboration between first author women and last author men were similar in the USA and Europe after the peak of the #MeToo movement (p=0.65).

The #MeToo movement was not associated with a reduction in the rate of scientific review article authorship collaborations between first author women and last author men in the life sciences. These findings, if generalizable, suggest it is possible to promote accountability for harassment in the workplace without limiting decreases in collaboration.
