Science: Around 350 000 people in 66 countries participated in a study of explicit and implicit associations between gender and science. Each participant was asked how strongly they associated being a scientist with being either male or female. Then each participant was asked to categorize displayed words. For some questions, the participants pressed one key to signal “male” or “science” and another key to signal “female” or “liberal arts.” For other questions, the keys signaled “male” or “liberal arts” and “female” or “science.” The differences in response times are used to determine when the key’s gender doesn’t align with the participant’s implicit bias. Both the explicit and implicit tests showed a global association between being male and being a scientist. The results correlated with the percentage of women in each country earning an undergraduate degree in science.
