Did you know it's illegal in the state of California to administer an IQ test to a black child? [1] This is a fantastic episode from radiolab about the history of IQ tests in the US and goes into how a test can be racist even without seeming so.
No I did not. Nor I believe that properly constructed test, with all explicit cultural references removed can be racist. Asians, straight from Korea or China, with some basic knowledge of English are able to reach normal or above normal results on IQ tests.
