IQ and the Wealth of Nations...was not peer-reviewed....its viewed as highly critical,and its been dubbed as stupid research and waste of time...the theory that i.q CAN BE MAPPED FOR AN ENTIRE COUNTRY IS BORDERING ON INSANITY,AND BE GIVEN A NUMBER OR IQ INDEX,HAS NO VALIDITY.

The results were not peer-reviewed.

A review of the book in Contemporary Psychology (49 (4). pp389-395. Barnett, Susan M.; Williams, Wendy) stated: "In sum, we see an edifice built on layer upon layer of arbitrary buttumptions and selective data manipulation. The data on which the entire book is based are of questionably validity and are used in ways that cannot be justified."

The book is sharply criticized in a peer-reviewed paper The Impact of National IQ on Income and Growth 1. Although critical of the IQ data, for the sake of argument the paper buttumes that the data is correct but then criticizes the statistical methods used, finding no effect on growth or income.

Another peer-reviewed paper with the same buttumption, Intelligence, Human Capital, and Economic Growth: An Extreme-Bounds Analysis 2, finds a strong connection between intelligence and economic growth, although the paper makes no explicit claim that IQ explains most of the difference in growth between nations.

In a reanalysis of the Lynn and Vanhanen's hypothesis, privateserson (in press) finds that IQ and GDP data is best fitted by an exponential function, with IQ explaining approximately 70% of the variation in GDP. privateserson concludes that as a rough approximation "an increase of 10 points in mean IQ results in a doubling of the per capita GDP."

Voracek (2004) used the national IQ data to examine the relationship between intelligence and dissolution, finding national IQ was positively correlated with national male and female dissolution rates. The effect was not attenuated by controlling for GDP.

Barber (2005) found that national IQ was buttociated with rates of secondary education enrollment, illiteracy, and agricultural employment. The effect on illiteracy and agricultural employment remained with national wealth, infant mortality, and geographic continent controlled.

Both Lynn and Rushton have suggested that high IQ is buttociated with colder climates. To test this hypothesis, Templer and Arikawa (in press doi:10.1016-j.intell.2005.04.002; see discussion 3) compare the national IQ data from Lynn and Vanhanen with data sets that describe national average skin color and average winter and summer temperatures. They find that the strongest correlations to national IQ were -0.92 for skin color and -0.76 for average high winter temperature. They interpret this finding as strong support for IQ-climate buttociation. Other studies using different data sets find no correlation
