From: Gender demographics of departmental seminar speakers reflect gender disparities of faculty hosts

Female and nonbinary faculty invited higher fractions of female and nonbinary speakers. A Aggregated data of seminars conducted in 2015–2019, categorized by whether the host faculty member was identified as male or female/nonbinary (Female/NB). Female and nonbinary faculty invited higher fractions of female and nonbinary speakers across nearly all departments. *p < 0.05 using a Paired t-test. N = 7 departments. B Data from A disaggregated by department. In all departments but department G, female/nonbinary faculty invited a greater fraction of female/nonbinary speakers than male faculty in the same department. N = 7 departments. C Fraction of Female/NB invited speakers in a given academic year, disaggregated by host gender. A simple linear regression was performed using the mean across departments for each year. Both male hosts and female/NB hosts show an apparent increase in fraction of female/NB invited speakers over time, with female faculty consistently inviting a higher percentage than male faculty. Plotted points represent the mean of all departments, and data for a given year were only included if n ≥ 6. Linear regression fit for male faculty hosts R2 = 0.4311 and for female faculty hosts R2 = 0.1924. The difference in the intercepts was significant, p = 0.0016. Error bars represent the standard error of the mean. N = 6 departments
