Most of Derbyshire’s statistics came from Charles Murray's book “The Bell Curve.”
That book has been favorably reviewed or referenced dozens of times by Rich Lowry’s magazine, National Review.
There have been several hundred comments and papers published about “The Bell Curve” in scientific and social science journals.
Many, of course, were critical.
But a majority support Murray's methods and conclusions.
One test might interest you.
Great Britain has given IQ tests to young children for more than a half a century, most of them white, until recent years.
There is an irrefutable correlation between high IQ and high income, good health, and long life.
Not exactly. Little reasonable fault was found with his methods. But a great many dispute his conclusions. Generally for not much more reason than they don't like them.
I recently ran across the book at a garage sale for $1. Why not?
I'd never read the book, but remembered the fire storm over its racism.
Imagine my surprise that race wasn't even the main focus of the book, although the authors were too honest to dodge the racial issue.
The main focus was how we should deal with a society evolving that has less and less economic use for less-intelligent people. IOW, what are we going to do with these people?
As automation continues and accelerates, the lack of demand will move farther and farther to the right on the IQ scale. For instance, it is likely that within less than 10 or 15 years the task of vehicle driving will largely be done by computers. Fine, you might say, but what are all those presently driving going to do to make a living? I've seen people point out the growing market for development of apps. Does anybody seriously believe large numbers of laid-off truck drivers can be retrained to develop apps for a living?
Murray and his co-authors attempted to address this issue, which is at the core of the "inequality" issue behind Dem propaganda and the OWS people. AFAIK, nobody else has. This is the biggest issue of our time, by far, and absolutely nobody is paying any attention to it.
BTW, it has a tie-in with Derb's screed. If black intelligence is indeed so much lower than that of whites, they will become "obsolete" sooner than whites, on average.
What do we do when larger and larger numbers of our people are obsolete?
