These findings in Lynn's latest book have profound geopolitical significance. They imply it may simply not be possible to transmit Western-style democratic and economic systems to the populations of Latin America and Moslem North Africa and the Middle East, let alone sub-Saharan Africa. They mean that the world's long-term problems will stem from its populations' capabilities-much deeper and more intractable than any "Clash of Civilizations"-style competition between different political concepts.
The implications for immigration are obvious: it can have fundamental, and permanent, consequences.
Lynn's book reviews more than 500 published IQ studies worldwide from the beginning of the twentieth century up to the present, devoting a chapter to each of the ten "genetic clusters", or population groups, as identified by Luigi Cavalli-Sforza and his colleagues in their mammoth 1994 book, The History and Geography of Human Genes.
Lynn regards these genetic clusters as "races". He concludes that the East Asians-Chinese, Japanese and Koreans-have the highest mean IQ at 105. Europeans follow with an IQ of 100. Some ways below these are the Inuit or Eskimos (IQ 91), South East Asians (IQ 87), Native American Indians (IQ 87), Pacific Islanders (IQ 85), South Asians and North Africans (IQ 84).Read more ›
Chapter 1 defines `intelligence' and motivates why IQ is a measure of it. Chapter 2 justifies the concept of `race' - depressing that this is thought to be necessary - and makes the argument of the first paragraph above.
Chapters 3 - 12 then itemise in great detail the results of numerous intelligence tests given to nine racially-distinguished populations: Europeans; Sub-Saharan Africans; Bushmen (South Africa) and Pygmies; South Asians (Middle-East, India, Pakistan) and North Africans; Australian Aborigines; Pacific Islanders; East Asians (China, Japan); Arctic People and Native Americans.
Base-lining Europeans at IQ = 100, Sub-Saharan Africans come out at around 67. Corrected for poor environmental conditions, Lynn estimates the genotypic IQ (the mean IQ Africans would have if raised in the same environment as Europeans) as around 80. Conversely, East Asians seem to have IQs centred around 105 (p. 130) while some populations of Ashkenazim Jews have mean IQs between 107-115 (p. 94).
Chapters 13-17 summarise racial differences, and propose an explanation based on the geographic radiation of homo sapiens out of Africa, the resulting geographical isolation of sub-populations, and the impact of two ice-ages (the first from 70,000 to 50,000 years ago, and then the more severe Wurm glaciation, 28,000 to 10,000 years ago).Read more ›
This book is perhaps of ultimate importance in its discussions of the importance of micronutrients--a factor that is possible to improve. Highly recommended!
Besides the tables, it has a worthwhile discussion of "race denial" among certain (mostly) American academics, and the usage of unhelpful euphemisms for race, such as "geographic groups" and "clusters" used by such as Cavalli-Sforza. I had to agree with him.
However, I am not sure that his explanations of the data (ice-age challenging environment) are anything more than plausible. They are certainly incomplete. His discussion of nutritional effects, so often proposed to explain the data, was clear and devastating, I thought. But, on the other hand, I wish he had included some discussion of the other moments of the distributions among different races. Surely there is some data on this. Averages are very important, but so is the variance, and skewness too.
This is an important book. It brings the data into sharp relief, and should be read by all race deniers. Some might even be cured.
