AFQT scores (iq test by the military) correlates .36-.37 with income for whites/blacks. How significant is this correlation? I spoke to a few friends that know about psychometrics they said it doesn't have much predictive power since the minimum g loading for each sub test on a Pro test is .7 and the g loading of the entire test is .9 ish. Thoughts?
