Review of “The Global Bell Curve” by Richard Lynn

This is the first book by Richard Lynn that I have read. This book is designed, by Lynn, to supplement The Bell Curve. The Bell Curve spends some time discussing the gap between black and white IQ in the US. It spends a very limited amount of time discussing the IQs of other racial groups (Hispanics, Asians and Jews) in the US. The book then goes on to discuss various implications of differences in IQ and sorting by IQ. The Global Bell Curve expands on racial differences in IQ – it does not expand on the other secondary topics discussed in The Bell Curve.

The point of The Global Bell Curve is to show that IQ differences by race are consistent in all countries with sizable communities of different races. Lynn covers Africa, Britain, the Netherlands, Southeast Asia, Australia, New Zealand, Brazil, Latin American, the Caribbean and the US.

Across all these countries IQ gaps across races exist. In fact, the gaps are – for all intents and purposes – the same between the same races. The evidence is fairly overwhelming, so much so, that the book actually becomes pretty boring. The studies are numerous and the findings are basically the same. Once you’ve read one chapter you’ve basically read them all. IQ is covered first, followed by differences in earnings, socioeconomic status, education, crime, fertility rates, and infant mortality (topics are covered where data is available). These other areas follow IQ, such that groups with higher IQs have higher earnings, have higher socioeconomic status, have more education, commit less crime, have fewer children and have higher rates of infant mortality. If Jews are in the country, they have the highest IQ, followed by some east Asians (Japanese and Chinese), followed by whites, followed by Indians, Southeast Asians, Pacific Islanders, Native Americans, Blacks and finally, Australian Aborigines.

Honestly, your mind is pretty dull to the findings after a while – they are so well-documented and so predictable. The thing that rescues you from your boredom is the conclusion sections of each chapter, in which Lynn reviews the work of other sociologists in the particular country analyzing why incomes (for example) differ across the country’s racial groups. Invariably, these sociologists never mention IQ.

(For some reason, the policies to remedy racial "disparities" proposed by these sociologists seem to keep failing.)

The analysis bolsters the evidence for a black-white IQ gap presented in The Bell Curve. It’s impossible to argue that the black-white IQ gap in the US caused by biased tests, when the IQ results for blacks in other countries are virtually identical to IQ results for blacks in the US. One would have to argue that insidious racists control all IQ tests everywhere and to such an extent that they make the results nearly identical. Isn’t the simpler answer that IQ is heritable and varies by race and that IQ further is highly correlated with income, education, crime and fertility (among other things)?

It was particularly shocking to see how much evidence there is for racial IQ gaps while Climate Gate was still in the news. "Consensus," of course, tells us that there is no biological cause for racial IQ gaps and it also tells us that man-made global warming is real and fully documented. In reality, the evidence overwhelmingly suggests that there are biological causes for gaps in IQ across races. By comparison, in light of Climate Gate, the evidence to support man-made global warming, with glaciers melting next year and drowning half the people in the world, looks like unicorns and moonbeams. But remember, all good people know that IQ is pseudo-science. Global warmism is the real science. Surely, there will be some evidence for these positions at some point in the future, for know, we’re just supposed to believe.
