For years, companies, universities and nonprofits have researched the reasons why women are less likely to enter STEM fields — and why, once they enter, they face challenges that frequently push them out. In prior research, we at the Center for Talent Innovation (CTI) found that women leave STEM fields in droves: 52% of highly qualified women working for science, technology, or engineering companies leave their jobs. We, and others, have found that the cultures surrounding women in STEM have been shown, time and again, to be particularly challenging.
