>>this article makes it sound like testing at all is discriminatory.
The reality is that any g-oriented test is going to favor, pretty much in order, Ashkenazi Jews, people of Han Chinese background, and Whites, and not favor Hispanics and Blacks.
You can argue about why that is so, but arguing that is isn’t so is denial of reality. It has nothing to do with any cultural biases in the tests, as the politically correct would have you believe.
While such tests probably shouldn’t be the only criterion for promotion for most jobs, there are plenty of jobs for which it should be an important element. The fact that the politically correct demand this not be so is just further proof that Liberalism is a mental disease. You don’t throw away a key indicator of future success just because you don’t like the results.
It wouldn't have anything to do with IQ because of genetics would it?
