"It is confidently known that brain size is correlated with IQ, IQ measured in childhood is correlated with income as an adult, and parental IQ is correlated with childrens IQ, Murray wrote in an e-mail. I would be astonished if childrens brain size were NOT correlated with parental income. How could it be otherwise?" That there is what one calls irresponsible science commentary."
Poor Charles Murray, he had to learn the hard way that science has no business getting in the way of political correctness.
The Bell Curve is one of the most astonishingly prescient books ever written. Its basic point was simply that our society is moving towards one in which there is little economic or social demand for low-IQ people.
Every single trend it described 2 years ago has continued and accelerated. And absolutely nobody wants to talk about them, because they don’t fit into neat categories of today’s political thought.
Sadly, the authors were intellectually honest enough to include a chapter on racial differences in IQ. Not at all the focus of their book, but it of course became the focus of 99%+ of the discussion about the book.
Which is of course why it’s now “discredited.”
That quote says no such thing.
It says if A is correlated with B, and B is correlated with C, then C can be expected to be correlated with A.
It says nothing at all about why A is correlated with C.
It is also fascinating that the author blows the "irresponsible scientific commentary" whistle but feels no need whatsoever to explain why what Murray said is either unscientific or irresponsible.
The truth will set you free...or get you labeled a racist hater if the truth “offends” someone.
