Because of the new study which uses genetic analysis to estimate that at least “40% of the variation in crystallized-type intelligence and 51% of the variation in fluid-type intelligence between individuals is accounted for by [genetics]” Charles Murray writes “Shelves of books and articles denying or minimizing the heritability of IQ have suddenly become obsolete. Those who continue to claim that IQ tests don’t measure anything real inside the brain also have their work cut out for them.”


It will be interesting to observe how professors who have ridiculed the importance of IQ will deal with genetic studies that undermine their previously held beliefs.


Note:  nothing in the new study provides evidence for Murray’s “Bell Curve” theories.
