David C. Geary and Gijsbert Stoet examine the STEM fields’ renowned gender disparities:
Many academics in the modern world seem obsessed with the sex difference in engagement with science, technology, mathematics, and engineering (STEM) fields. Or rather they are obsessed with the fact that there are more men than women in some of these fields. There is particular concern about the lack of women in prestigious STEM fields, such as Ph.D.-level faculty positions, but surprisingly there is no concern about the under-representation of women in lower-level technical jobs, such as car mechanics or plumbing.
The concerned academics have been especially effective in convincing others, or at least intimidating them, into accepting their preferred interpretations regarding the source of these sex differences (as illustrated in the Google memo debate). These interpretations are not surprising and they include sexism, stereotype threat, and more recently implicit bias and microaggression. Each of these ideas has gained traction in the mainstream media and in many academic circles but their scientific foundations are shaky. In this essay, we’ll provide some background on the STEM controversy and consider multiple factors that might contribute to these sex differences.

We’ve recently found that countries renowned for gender equality show some of the largest sex differences in interest in and pursuit of STEM degrees, which is not only inconsistent with an oppression narrative, it is positive evidence against it. Consider that Finland excels in gender equality, its adolescent girls outperform boys in science, and it ranks near the top in European educational performance. With these high levels of educational performance and overall gender equality, Finland is poised to close the sex differences gap in STEM. Yet, Finland has one of the world’s largest sex differences in college degrees in STEM fields. Norway and Sweden, also leading in gender equality rankings, are not far behind. This is only the tip of the iceberg, as this general pattern of increasing sex differences with national increases in gender equality is found throughout the world.
The recent uptick in interest in concepts such as stereotype threat, implicit bias, and microaggression may be a reaction to the low female STEM participation in highly developed nations. At one time, there were substantive social and educational impediments to women’s participation in these (and other) fields, but as explicit sexism and restricted educational opportunities faded into history, the sex differences (e.g., fewer women than men physicists) attributed to them should have faded as well. Some of them have even reversed, such that more women than men attend and graduate from college and women may now have structural advantages (e.g., hiring practices) in STEM fields. Even with these changes, many other sex differences remain or have become larger over time. The latter are serious problems for anyone with strong beliefs about purely or largely social influences on sex differences; if the obvious social causes have been addressed, then there must be other, more subtle oppressive factors afoot. This is where stereotype threat, implicit bias, microaggression and related concepts enter the oppression narrative.
We believe that with economic development and advances in human rights, including gender equality, people are better able to pursue their individual interests and in doing so more basic sex differences are more fully expressed. The differences in STEM are related in part to student’s personal and occupational interests and relative academic strengths. Sex differences in occupational interests are large, well-documented, and reflect a more basic sex difference in interest in things versus people. Men prefer occupations that involve working with things (e.g., engineering, mechanics) and abstract ideas (e.g., scientific theory) and women prefer working with and directly contributing to the wellbeing of others (e.g., physician, teacher). The sex difference in interest in people extends to a more general interest in living things, which would explain why women who are interested in science are much more likely to pursue a career in biology or veterinary medicine than computer science.
Programs designed to steer women into inorganic STEM fields would in effect steer these same women away from the life sciences. Such programs would, in our opinion, only be justifiable if women are not provided a fair opportunity to pursue inorganic STEM fields (for which there is no good evidence). The main argument from gender activists is that inorganic STEM fields are a better choice for women either because these jobs lead to higher incomes or that there is a labor market demand for them. Both arguments are fundamentally capitalist and dehumanizing in the sense that considerations of personal interest are overridden by considerations of societal demand. This is ironic, given that the agenda arguing for more women in STEM seems most popular among left-leaning people.
