degsme:"predictively unbiased" Sorry don't buy that this has been fully demonstrated at all.
Essentially this is just racial mythology repackaged as "science"
Evidence showing that tests are valid for Whites, but not for Blacks does not occur any more than would be expected solely by chance. Here are a handful of studies to support this statement.

Furthermore, lower test scores among minorities are accompanied by subsequent lower job performance, the same as for Whites. Likewise, higher scores predict higher job performance. This holds for supervisory ratings and objective measures of performance. That is, they are not predictively biased. There is ample evidence to support this claim.
