Study finds that women’s names filled just 23% of author slots in 900 retracted articles published in medical journals (2008 - 2017). One possible explanation: women are more detail oriented & know they will be subject to scrutiny; thus are more careful.

Women seem to retract fewer papers than men — but why?
In an analysis of nearly 900 retracted medical research studies, the number of female authors is disproportionately low.
