These tests attempt to model your unconscious prejudices. They do it by asking you to sort words and pictures very rapidly. For instance I ran a test about Bush and Kerry. First it asked me to sort pictures of Kerry against good words (and bad words against Bush) and then vice versa (Kerry/bad against Bush/good). It picked up that I sorted slower when I was trying to match 'good' words' with pictures of Bush, and concluded that I had a strong visceral dislike of Bush. Which is correct of course.
I then did another couple of test which said that
- I moderately associated 'male' with science and 'female' with liberal arts
- I moderately associated 'homosexual' with 'good' concepts (that surprised me; I thought I would be neutral)
The demonstration section includes tests about race, age, and fat vs thin, which I haven't tried yet. In the main section there are apparently 60 tests in all (that's where I got the Bush Kerry one) but they are selected at random when you sign in, and your results are used in developing their research.
