Background
Innovation in STEM (science, technology, engineering, and math) fields in the U.S. is threatened by a lack of diversity. Social identity threat research finds messages in the academic environment devalue women and underrepresented groups in STEM, creating a chilly and hostile environment. Research has focused on the mechanisms that contribute to STEM engagement and interest at the K-12 and undergraduate level, but the mechanisms that predict sustained engagement at the graduate level have not been studied.
Results
In a longitudinal study of doctoral students in STEM disciplines, we demonstrate that students’ beliefs that their STEM colleagues believe intelligence is a fixed (vs. malleable) trait undermine women’s engagement in STEM. Specifically, perceiving a fixed ability environment predicts greater perceptions of sexism, which erode women’s self-efficacy and sense of belongingness and lead women to consider dropping out of their STEM career.
Conclusion
These findings identify one potential pathway by which women leave their STEM fields, perpetuating gender disparities in STEM.
