NYT article on measuring racial bias 

 In today's paper, the NYT reports on an interesting debate between two groups of researchers regarding studies on unconscious racial bias (`` In Bias Test, Shades of Gray '').  The discussion centers around the usefulness of an online test, the Implicit Association Test, which measures how quickly respondents associate ``good'' or ``bad'' words with blacks or whites.  How useful are such tests?  It does seem crude as metric for racial bias (try it yourself  here ).  But I suspect that they have raised awareness and deserve credit for involving a wide audience.  Yet despite its timid recommendations and disclaimers when the results are displayed the test could also be misleading: what if you're characterized as racially bias (but are not)?  What if you're characterized as unbiased (but are and should be told)?
