This was marked as a “Cool Site” by the Special Library Associations e-mail newsletter. And it is just that. You can do demo tests related to this research being done by Harvard.
The tests measure response time when sorting words into good and bad and sorting images and words related to some other variable. I was really surprised to find out that I slightly to moderately preferred that which was most similar to me on every test I took. I was even more surprised when I slightly preferred non-Arabic names to Arabic names because my very own last name was one of the examples of an Arabic name that was used. The tests don’t say much about what one really thinks, but just split second subconscious reactions. I found the political one rather amusing. On that, I learned that I like Nixon slightly more than George W. Bush. Poor Nixon, I barely know anything about the guy and I apparently dislike him quote a bit.
