I followed a link on one of the LJ communities and it was quite interesting about how one can measure known and unknown biases... It is an Implicit Associated Test, and I don't really know how I feel about it, but there is a test on people's attitudes towards disable vs abled people, arabs vs non-arabs, jews vs other religions, conserv vs liberal (JJ? up your alley?)
From Website:
"It is well known that people don't always 'speak their minds', and it is suspected that people don't always 'know their minds'. Understanding such divergences is important to scientific psychology."
You can try it out... it's interactive and a psychological tool of evaluation.
here's a link to some tests:
