Yes, 0.6 really is good correlation, but when compared to the 0.8795
correlation between brain size and GRE Quantitative, you have to wonder
what's missing from "IQ tests".

iow, since it IS possible to develop a test which measures the output of the
thought process which DOES positively correlate so well with brain size,
then there must be a serious flaw in "IQ tests" since they don't correlate
as well.

In fact, it's difficult to imagine how this could happen by accident, so I
look forward to seeing what data you have that shows an 0.86 correlation.

How could Wechsler possibly accidentally develop a test which is supposed to
measure "intelligence" which seems to be measuring something else?

The answer's in Peter's original thesis.
