@makeworld @viraptor @aimaz @bontchev if you get two identically educated and raised people to take the same test, then that might tell you that the one who did better on the test is smarter.
That doesn't mean that the test itself is a good one, nor does it preclude it from being racist and pseudoscientific.
@makeworld @viraptor @aimaz @bontchev BMI is another completely inaccurate, flawed and pseudoscientific metric. Yet it's still used near universally by the medical profession.
Why is that? Because it's good and robust? Or just because it's easy and convenient and everyone's used to it and the people harmed by it aren't usually the same people as the ones using it?
