I would ask people not to take the test immediately, but rather first spend time on the authors' distinction about implicit racial attitudes. Racial bias in this sense is entirely different than overt racism, but still as important. Admitting that you've unintentionally learned the statistical biases present in our culture is not admitting you're a racist. When you're ok with that statement (which can be difficult given the charged USian history of race!), take the test.
