From 2003 to present, the Gender-Science IAT was available on the Project Implicit demonstration website (https://implicit.harvard.edu/implicit/selectatest.html Click on “Gender-Science IAT” to try it yourself). The Gender- Science IAT includes one standard IAT (Male vs. Female; Science vs. Liberal Arts), sets of explicit measures on gender roles (such as association of science/liberal arts with females or males, personal attitude toward science/liberal arts), set of demographic questions (age, gender, education level, etc.), and debriefing questions about how respondents thought about their IAT score after the task. From 2003 to the end of 2017, there are more than 1,469,285 session IDs created for Gender-Science IAT, and the overall completion rate is around 48.3%. There were 876,088 respondents who completed the standard IAT part of the task, which is 59.6% of the total respondents. Under this OSF project, you may download 1) Gender-Science IAT data sets with IAT score computed, self-report data labeled, and demographic information by year or for all years; 2) codebooks associated with each data set; 3) experiment materials and description of procedure; 4) Skeleton syntax for SPSS to start your own data analysis. The public data sets don't have participants' zip code/postcode to protect privacy. The data sets, however, have state, county, Metropolitan Statistical Area information for respondents who reported US zip codes.
