64 Jensen's evidence has been accompanied by a debate over his method
of correlated vectors for testing Spearman's hypothesis. P.H.
Sch?nemann has argued, most extensively in Sch?nemann (1997), that
Jensen's evidence was no more than a statistical artifact, a claim
refuted by Dolan and Lubke (2001). But other ways in which the method
of correlated vectors might yield Atenolol 12.5 Mg spurious results are still being
debated; e.g., Dolan (2000), Lubke, Dolan, and Kelderman (2001),
Dolan, Roorda, and Wicherts (2004), Ashton and Lee (in press). These
arguments are being carried on at an arcane methodological level. I
am Atenolol Tablets 50mg making a limited claim about what Purchase Atenolol Jensen has Generic Atenolol established beyond
dispute: when you take a battery of mental tests, subject them to a
factor analysis, and correlate the loadings on the first factor with
the size of the black-white difference, the correlation will average
about .6. The actual method of correlated vectors is more complicated
than this, and is described in Jensen (1998): 372-74.
65 Factor analysis can be conducted in many different ways, which has
led to Atenolol 50 Mg Tablet widespread popular acceptance of one of Stephen Jay Gould's
allegations in his best-selling book, The Mismeasure of Atenolol 5 Mg Man (1981),
namely, that g is a statistical artifact that appears only when
certain analytic choices are made. Atenolol 25 Mg Tablet Actually, the opposite is true. A
single factor, typically explaining about three times as much
variance as all the other factors combined, emerges under all of the
normal Atenolol Buy methods of conducting a factor analysis. The only exception
occurs if the factor-analysis program is explicitly instructed to
apportion the variance in such a way that a single factor does not
emerge. But Atenolol 40 Mg if you do that and then try to publish your results, the
reviewers will point out Atenolol 50mg Tablets that if you hadn't issued that instruction,
you would have gotten a dominant single Atenolol 25 Mg Tablets factor. As Richard Herrnstein
liked to say, "You can make g hide, but you can't make it go away."

70 Let it be clear: I am not asserting Atenolol 10 Mg that putting these two facts
together proves that the black-white difference is genetic. The logic
of the situation was memorably converted to an analogy Atenolol 25mg Tablets in Lewontin
(1970) Purchase Atenolol Online and adapted in Herrnstein & Murray (1994): 298. If you take
two handfuls of genetically identical seed corn and plant one in Iowa
and the other in the Mohave Desert, you will get a large group
difference in results despite the high heritability of the traits of
corn. William Dickens and James Flynn have operationalized the
analogy through a simulation model that produces a large black-white
difference from environmental factors even given high heritability
(Dickens and Flynn 2001). The validity Atenolol 15 Mg of that model was subsequently
disputed by Loehlin (2002) and Rowe and Rodgers (2002), with a reply
by Dickens and Flynn (2002). But that debate does not pertain here.
The implications I describe follow simply from Atenolol 20 Mg knowing that g is
highly heritable among blacks, as it is among all groups, and that
the black-white difference is largely a difference in g.
