Is science a future path for girls? According to UNESCO's Institute for Statistics, only 28% of the world’s researchers are women. Despite progress over time, women remain underrepresented — especially in STEM fields (Science, Technology, Engineering, and Mathematics) and in leadership positions in research. It’s not that women are absent from science — but as career levels rise, female representation declines.
Research shows that one cause of this disparity is the persistence of gender-related stereotypes, even within science itself. A Swedish study with 1,327 students, published in Sex Roles (2017), found that “social belonging” strongly influenced career choices: more boys opted for STEM, while girls chose health care, early childhood education, or domestic sciences — even in a country with high gender equality.
But what is “social belonging”? According to the study, teenagers tend to feel more comfortable in environments where their own gender is better represented. In a vicious cycle, many girls end up believing they’re not as capable in STEM, despite often outperforming boys in school subjects.
This perception can begin long before university. Another study, published in Science (2017) by U.S. researchers, showed that five-year-old girls are just as likely as boys to say "girls can be really, really smart." But from age six, girls start to believe that brilliance is more likely a male trait. At the same age, girls show more interest in games for children who “work hard” rather than those “who are very smart” — even when they perform better academically than boys.
