A recent hot search on the WWW is the Racist Test. This test is a demo presented by Harvard University. There are actually 12 tests here and we don't see that they indicate racism as much as "preference" and your ability to pick out symbols and indicators of race, religion, etc. Maybe these are more tests of prejudice, not racism. Is there a difference?
Anyway, the folks at Harvard are the scientists, not us.
Take the tests HERE.
