From 2006 to present, the Race IAT was available on the Project Implicit Netherlands website (https://implicit.harvard.edu/implicit/netherlands/selectatest.jsp Click on “Ras” to try it yourself). The Race IAT includes one standard IAT (Good vs. Bad; White People vs. Black People), sets of explicit measures on attitudes related to race (such as preference for black people and white people etc.), set of demographic questions (age, gender, race, major, political identity, etc.), and debriefing questions about how respondents thought about their IAT score after the task. The study is in Dutch.
From 2006 to the end of 2017, there are 65,080 session IDs created for the Race IAT, and the overall completion rate is around 36.9%. There are 30,032 respondents who completed the standard IAT part of the task, which is 46.1% of the total respondents.
