a couple of points, neither of which seems very relevant to me. (1)If you have consistent correlations among
measurements, factor analysis can extract a largest principal component and (2)One factor does not completely
describe performance on mental tests. The first is a tautology and the second has been known almost forever
(again, from factor analysis.)
Neither point does anything to cast doubt on the usefulness of IQ as a concept or as a technique for judging
potential capabilities. Yet another pointless screed on IQ.
