i guess i disagree w author of paper you quoted. "we have multiple faculties" != "statistical independence on tests"

e.g. in fitness example, "faculty physiology" is /true/ (muscles and heart are distinct etc) yet we see pos correlations

cpu speed and ram size are distinct "faculties," but i'm sure the two are correlated in "population" of existing computers

That's an argument regarding *why* they correlate. Different to what laymen or educated people expected/expect

I'm glad if in your bubble(non-pejoratively,as opposed to mine) it doesn't happen, but I've heard several times people...

expecting that if X person/kid it's bad at maths, then at least he should be good at reading, and/or viceversa

hey, if you predict IQ from other knowledge about kid and condition on prediction, that's a perfectly good inference :P

more seriously, i know people argued hard against positive manifold, but do we know they wouldn't do the same for fitness?
