Average IQ of CountriesThe average IQ in the United States is usually set at 100. Groups within the US score different average IQ's, such as 115 for college grads or 85 for African-Americans. Similarly, average IQ varies from country to country, shown in the 2002 book IQ and the Wealth of Nations (sets Britain at 100):

Given that most of the lower ones are African nations I wonder if poor nutrition through drought after drought would affect IQ overall. I guess that would come under your "been poor for generations mean that their IQ average is low" theory.
Research shows that IQ accounts for only 1/3 or less of a person's income - within a country. Other big factors in income are a person's social skills and ambition, together sometimes called Emotional Intelligence.
While social skills have a major impact on a person's income within a country, they have little effect on national income. The reason? Research indicates that average social skills (SQ) scores show almost no differences among racial groups. Ambition may have a similar worldwide pattern. As a result. IQ becomes the main cause for national wealth differences. Click for more information on how IQ, social skills and ambition relate to national wealth.

Graphs of IQ and Economic Success
The relationship between IQ and individual achievement is well known. No where is it better documented than in Herrnstein and Murray's The Bell Curve (Free Press, 1994). Lynn and Vanhanen have scaled this connection up to a national level. They expose a relationship between national wealth and IQ. You can see the relationship best in a graph (Figure 1).
Figure 1. Per capita GDP vs. national average IQ. The regression line is shown in red.. Notice how GDP is positively correlated to average IQ. The correlation coefficient is 0.733, IQ explaining 54 percent of the GDP variance. Values this large are rare in social science. In the social sciences, correlations of 0.2 are said to be "low," 0.4 are "moderate," and 0.6 are "high." So 0.73 is most impressive.

South Africa is the world's largest producer of platinum, gold, chromium and diamonds. None of this has much to do with human resources. Barbados and Qatar have also been favored with wealth-producing assets. Barbadian economy is based mostly on tourism. Exceptional year-round climate combined with proximity to the US strengthens its economic base irrespective of IQ. Similarly, oil revenue accounts for Qatar's extraordinary GDP. Finally, with a market economy being necessary for prosperity, we find Communist China, with a mean IQ of 100, producing more like a country with a mean of 83. When the four outliers are removed, the correlation grows from 0.73 to 0.79. In this case, 62 percent of the remaining GDP variance is now explained by IQ.
Racial/ Ethnic Differences graphed:
In Figure 2 below, the data is divided into contributions from four groups: blacks, (European) whites, East Asians and "others," The "others" include Asian Indians, Latin Americans, Pacific Islanders, Middle Easterners, other Asians, etc. Many of these countries have racially or ethnically heterogeneous populations. The outliers (South Africa, Barbados, Qatar and China) are not included in the graph:
Figure 2. Per capita GDP by racial group. "White" here means European white; "East Asian" means the racially homogenous polities: Taiwan, South Korea, Hong Kong, and Japan. IQs cluster by race.
East Asian points are off the graph's trend line
Taiwan, Japan, South Korea and Hong Kong, all with homogeneous populations, have the highest IQs reported here. We might therefore expect them to be among the wealthiest of nations. Their numbers, especially those of Taiwan and South Korea, however, tell another story. With average IQs of 104 and 106, respectively, per capita GDPs of about $13,000 seem much too low for Taiwan and South Korea.
Country average IQ and per person GDP ($13.000 for Taiwan)
Taiwan 104 13,000
South Korea 106 13,478
Hong Kong 107 20,763
Japan 105 23,257
The observations raise questions about East Asian achievement. IQ alone does not determine wealth. Perhaps East Asians are wanting in other attributes. Or, maybe there are aspects of Eastern culture that undercut creativity. These questions need to be investigated.
