Gender and STEM

Despite having made significant inroads into many traditionally male-dominated fields such as law and medicine, women continue to be starkly underrepresented in fields such as computer science (Cheryan, Ziegler, Montoya, & Jiang, 2017). Many theories have been put forth to explain women’s underrepresentation, ranging from innate female inferiority in quantitative skills to an unwillingness by women to sacrifice time with family. Our research shifts the explanation for underrepresentation away from women’s deficiencies and instead examines whether it is the image of the field, fueled by inaccurate stereotypes, that interferes with women’s ability to see themselves in computer science.

We found that there were clear stereotypes of computer science students as people who, for example, “stay up late coding and drinking energy drinks” and have “no social life” (Cheryan, Plaut, Handron, & Hudson, 2013). In several behavioral experiments (Cheryan, Plaut, Davies, & Steele, 2009; Cheryan, Meltzoff, & Kim, 2011), we found that women who enter a computer science environment with objects stereotypically associated with the field (e.g., Star Trek posters, video games) are less likely to consider pursuing computer science than women who enter a computer science environment with non-stereotypical objects (e.g., art posters, water bottles). These results held even when the proportion of women in the environment was equal across the two types of environments. We then expanded to younger ages and found that computer science classrooms that do not fit current computer science stereotypes increase high school girls’ interest in computer science without deterring boys (Master, Cheryan, & Meltzoff, 2016).  In subsequent studies, we showed that encountering role models who exhibited the computer science stereotype in dress and preferences decreased women’s interest and anticipated success in computer science (Cheryan, Siy, Vichayapai, Drury, & Kim, 2011; Cheryan, Drury, & Vichayapai, 2013).

Why have some STEM fields (i.e., biology, chemistry, and math) been more successful in incorporating women and girls than other STEM fields (i.e., computer science, engineering, and physics)? We found that gender disparities exist when a field has two factors: a masculine culture and limited opportunities for pre-college experience. By first grade, girls and boys already believe that boys are better than girls at computer science (“programming”) and engineering (“robots”), and these stereotypes are stronger than their stereotypes about “math” and “science” (Master, Cheryan, & Meltzoff, 2017). However, allowing first-grade girls to play with a robot programming toy for 20 minutes increased their interest in learning computer science and engineering and had no similar effect on boys (Master, Cheryan, & Meltzoff, 2017).

Taken together, our work suggests that changing the masculine culture of computer science, engineering, and physics – for instance, using environments, media, and role models – may be fundamentally important to increasing women’s participation in them.
