From 2004 to present, the Race IAT was available on the Project Implicit UK website (https://implicit.harvard.edu/implicit/uk/selectatest.jsp Click on “Race” 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.
From 2004 to the end of 2016, there are 306,496 session IDs created for the Race IAT, and the overall completion rate is around 35%. There are 134,162 respondents who completed the standard IAT part of the task, which is 43.8% of the total respondents.
