The implicit Association Test (IAT) measures the strength of association between concepts and evaluations or stereotypes to reveal an individual's hidden or subconcious biases. The test was first published in 1998 by Project Implicit, and has since been continuously  updated and enhanced.

The IAT measures attitudes and beliefs that people may be unwilling or unable to report The IAT may be especially interesting if it shows that you have an implicit attitude that you did not know about. As I checked ther Project Implicit site, I found the following list of IAT:

• Race IAT
• Gender-Science IAT
• Gender-Career IAT
• Native IAT
• Age IAT
• Skin-tone IAT
• Transgender IAT
