I never heard of the institution that distributes opportunities based on the result of IQ test. I only heard about IQ test for police and for military. I'm not sure if that's what you mean by "one sided", but while you can find high IQ people in all walks of life it's very easy to find them in high achievers. And it goes way beyond lack of low IQ people. Even average IQ people are rare there.
