Is Intelligence related to your ethnicity or race?

Now this is sure to put the tiger amongst the chickens. Here is a report in the Independent. I quote from this Nobel Prize Winner's extraordinary statements as reported:

One of the world's most eminent scientists was embroiled in an extraordinary row last night after he claimed that black people were less intelligent than white people and the idea that "equal powers of reason" were shared across racial groups was a delusion.

There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so."

Curious, no? Before people climb up on the universality of human rights and all that and berate me, yes, I agree on that. But ability is different and you cannot mandate it. That is why I am a piss poor sportsman and Michael Jordan is a superstar. But earnings wise, I am in the top quartile of earners and presuming that link between earnings and ability, there is a reason for the difference.

Now nutrition has been shown as a direct contributor to intelligence. We also have direct links and studies for Ashkenazi Jewish Intelligence. (see abstract at the bottom for one research paper) We also have direct links and studies which show that a child of an educated person is more likely to be educated than otherwise.

Given this, the presumption that every human being is equally intelligent or able is not correct. But is this up to the melamine content in your skin? This professor thinks so!

This multifactorial study investigates the interrelationships between head circumference (HC) and intellectual quotient (IQ), learning, nutritional status and brain development in Chilean school-age children graduating from high school, of both sexes and with high and low IQ and socio-economic strata (SES). The sample consisted of 96 right-handed healthy students (mean age 18.0 +/- 0.9 years) born at term. HC was measured both in the children and their parents and was expressed as Z-score (Z-HC). In children, IQ was determined by means of the Wechsler Intelligence Scale for Adults-Revised (WAIS-R), scholastic achievement (SA) through the standard Spanish language and mathematics tests and the academic aptitude test (AAT) score, nutritional status was assessed through anthropometric indicators, brain development was determined by magnetic resonance imaging (MRI) and SES applying the Graffar modified method. Results showed that microcephalic children (Z-HC < or = 2 S.D.) had significantly lower values mainly for brain volume (BV), parental Z-HC, IQ, SA, AAT, birth length (BL) and a significantly higher incidence of undernutrition in the first year of life compared with their macrocephalic peers (Z-HC > 2S.D.). Multiple regression analysis revealed that BV, parental Z-HC and BL were the independent variables with the greatest explanatory power for child's Z-HC variance (r(2) = 0.727). These findings confirm the hypothesis formulated in this study: (1) independently of age, sex and SES, brain parameters, parental HC and prenatal nutritional indicators are the most important independent variables that determine HC and (2) microcephalic children present multiple disorders not only related to BV but also to IQ, SA and nutritional background.

Richard Lynn and David Longley, On the high intelligence and cognitive achievements of Jews in Britain, Intelligence, Volume 34, Issue 6, November-December 2006, Pages 541-547. Abstract: A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16 year olds in which Jews had mean IQs of 108.5 and 107.7. Taking all five studies into account, it is proposed that the best reading of the IQ of Jews in Britain is 110. It is proposed that the best reading of the IQ of Jews in the United States is 109.5. Data are presented for the numbers of Jewish Fellows of the Royal Society in relation to their proportion in the population. It is found that Jews were over-represented by a factor of 3.7 in the years 1901 through 1940 and by a factor of 7.6 in the years 1950 through 2003. Data are also presented for the numbers Jewish Nobel prize-winners in Britain and the United States for 1901 through 2003. It is shown that Jews are over-represented among Nobel prize-winners by a factor of 8.0 in Britain and 12.3 in the United States. It is proposed that the over-representation of Jews among Nobel prize-winners can be partly explained by the higher average Jewish IQ.
