Think of a scientist – not anyone in particular, just a random individual working in the field. Got one? Did you picture a man or a woman? If it’s the former, you’re probably not alone. There have been a few times when I’ve only ever known a scientist through their surname on a citation and automatically assumed that they were a man, only to learn, to my chagrin, that they’re actually a woman. It’s always a galling reminder of how pervasive the stereotype of science as a male endeavour can be, even at an unconscious level.
Now, Brian Nosek from the University of Virgina, together with scientists from over 14 countries, has charted the extent of these implicit associations across the globe, and shown that they predict the size of the gender gap in school-level scientific achievement.
Nosek suggests that these biases and gender gaps feed off each other in a vicious cycle. The sex differences already present in the sciences, especially at the top echelons, are hard to miss and they can make stereotypes feel very real. In one study, women who saw a conference video where three in four attendees were men (a very real situation for many female scientists) felt less belonging and less desire to participate.
Stereotypes can also create themselves. Women who buy into stereotypes are less likely to take up a maths or science degree. Even if they refuse to be pigeonholed, they can be so stressed about conforming to a stereotype that they actually increase the odds of doing by taking a hit to their performance. This phenomenon is called “social identity threat” and it’s evident in research that shows women do more poorly in tests if they have previously been reminded of the supposed male superiority or even, simply, if their gender is highlighted.
Nosek’s group relied on a powerful tool that provides a standardised measure of the strength of stereotypes across different countries – the Implicit Association Test (IAT). The computer-based tests ask people to group words into pairs categories using assigned keys. One key might represent male words (he, boy) as well as science words (physics, chemistry), while the second key might represent female words or arts-related ones.
