From 2008 to present, the Sexuality IAT was available on the Project Implicit Brazil website (https://implicit.harvard.edu/implicit/brazil/selectatest.jsp Click on “Sexualidade” to try it yourself). The Sexuality IAT includes one standard IAT (Gay/Lesbian vs. Straight; Good vs. Bad), sets of explicit measures on topics related to sexuality (such as frequency of contacting gay/lesbian people, opinion on gay marriage, parenting preference, etc.), set of demographic questions (age, gender, race, sexuality, political identity, etc.), and debriefing questions about how respondents thought about their IAT score after the task. The study is in Portuguese. From 2008 to the end of 2017, there are 25,588 session IDs created for Sexuality IAT, and the overall completion rate is around 28.3%. There are 10,033 respondents who completed the standard IAT part of the task, which is 39.2% of the total respondents.
