"Were found." Passive voice. Following the link, we discover that the "finder" is Judge Robert Peckham in 1979:

No offense, but who the fsck is Bob Peckham? And why should anyone in 2012 care what he thought in 1979? BTW, he was in a position to "find" because LBJ made him a judge in 1966. Hear LBJ's enlightened racial perspectives here:

I also like how IQ tests are racist against dumb black kids, but not smart black kids. That's some awful specialized racism you got goin' on there.
If you think something has changed since 1979 then the burden of proof is on you to show what that is, you don't get to just assert that everything is magically different now.
I think his argument was that a judicial determination in 1979 isn't really good evidence that it was true in 1979 either, because the courts aren't the most reliable judges of scientific facts.
[I haven't read enough of the voluminous literature on the IQ-test controversy to have an opinion myself, so I don't necessarily endorse that viewpoint.]
The issue is that IQ tests were found to be culturally biased against black students and therefore responsibly for placing those students on special-ed tracks that were not appropriate. See: http://www.rcselpa.org/docs/policies/Section%20III%20Evaluat...
This abstract indicates that black students seeking placement into gifted classes are exempted from the ban: http://pediatrics.aappublications.org/content/93/1/31.abstra...
