Preliminary Information

Whichever IAT you do, we will ask you (optionally) to report your attitudes toward or beliefs about these topics, and provide some general information about yourself. These demonstrations should be more valuable if you have also tried to describe your self-understanding of the characteristic that the IAT is designed to measure. Also, we would like to compare possible differences among groups in their IAT performance and opinions, at least among those who decide to participate.

Data exchanged with this site are protected by SSL encryption, and no personally identifying information is collected. IP addresses are routinely recorded, but are completely confidential.

Important disclaimer: In reporting to you results of any IAT test that you take, we will mention possible interpretations that have a basis in research done (at the University of Washington, University of Virginia, Harvard University, and Yale University) with these tests. However, these Universities, as well as the individual researchers who have contributed to this site, make no claim for the validity of these suggested interpretations. If you are unprepared to encounter interpretations that you might find objectionable, please do not proceed further. You may prefer to examine general information about the IAT before deciding whether or not to proceed.

You can contact our research team ( or Harvard's Committee on the Use of Human Subjects ( for answers to pertinent questions about the research and your rights, as well as in the event of a research-related injury to yourself.

I am aware of the possibility of encountering interpretations of my IAT test performance with which I may not agree. Knowing this, I wish to proceed.
