Dear Stephen and all,
Very interesting. Do Bouchard et al. also report
absolute values on those MMPI (and IQ) scales?
The reason I ask is because correlations are
(unit free) measures of association but not
of discrepancy. In fact, we know that linear
transformation do not affect them. Thus, if
for example the scores of twins rared with their
parents are 10 points higher than their co-twins
the correlations would not change much. Just curious.
