Comment on Expectations of brilliance underlie gender distributions across academic disciplines

Leslie et al. (Reports, 16 January 2015, p. 262) concluded that expectations of brilliance explained the gender makeup of academic disciplines. We reestimated their models after adding measures of disaggregated Graduate Record Examination scores by field. Our results indicated that female representation among Ph.D. recipients is associated with the field's mathematical content and that faculty beliefs about innate ability were irrelevant.
