Here's the site to take and learn about the Implicit Association Test (IAT)
https://implicit.harvard.edu/implicit/
Here you will have the opportunity to assess your conscious and unconscious preferences for over 90 different topics ranging from pets to political issues, ethnic groups to sports teams, and entertainers to styles of music. At the same time, you will be assisting psychological research on thoughts and feelings.
I have always found the IAT interesting. I remember last semester I showed my Introduction to Psychology class a video on this (it was a Scientific American Frontiers clip), and many of my students were very interested in it and wanted to learn more about it. Some of my students told me that they took the test outside of class and were very interested in the results. It seemed to make them more aware of the difference between conscious and unconscious thoughts, so I am glad that this test is available for use on the internet.
