A gender bias habit-breaking intervention led to increased hiring of female faculty in STEMM departments

Addressing the underrepresentation of women in science is a top priority for many institutions, but the majority of efforts to increase representation of women are neither evidence-based nor rigorously assessed. One exception is the gender bias habit-breaking intervention (Carnes et al., 2015), which, in a cluster-randomized trial involving all but two departmental clusters (N=92) in the 6 STEMM focused schools/colleges at the University of Wisconsin–Madison, led to increases in gender bias awareness and self-efficacy to promote gender equity in academic science departments and perceptions of a more positive departmental climate. Following this initial success, the present study compares, in a preregistered analysis, hiring rates of new female faculty pre- and post-manipulation. Whereas the proportion of women hired by control departments remained stable over time, the proportion of women hired by intervention departments increased by an estimated 18 percentage points (OR=2.23, dOR=0.34). Though the preregistered analysis did not achieve conventional levels of statistical significance (p
