A place for all? Feminine gender expression and communal opportunities in STEM bolster STEM belonging and motivation for sexual and gender minorities

Abstract Despite the importance of a strong science, technology, engineering, and mathematics (STEM) workforce, the culture of STEM deters many groups, including sexual and gender minorities (SGM) from entering STEM fields (i.e., women, Latino/a, Native American, first‐generation students). Because SGM individuals’ STEM belonging and motivation are believed to follow similar psychological processes to other underrepresented groups in STEM, we examined how expectations for success in STEM, personal endorsement of masculinity/femininity and agency/communion, and the masculine (unfeminine) and agentic (uncommunal) nature of STEM are associated with STEM motivation and belonging depending on participants’ sexual and gender identities. Men expressed greater STEM belonging and motivation than women, and STEM fields were perceived as more masculine and agentic than feminine and communal. Participants’ expectations for success in STEM were positively associated with STEM belonging and motivation. Perceiving agentic and communal opportunities in STEM also positively predicted STEM belonging and motivation. For SGM individuals, perceiving feminine gender expression in STEM was associated with increased STEM belonging and motivation (particularly for SGM women). Implications for addressing the underrepresentation of SGM individuals in STEM are discussed.
