IQ differences between black and white populations in the UK and elsewhere are virtually non-existent. In fact, Blacks of African descents in the UK, on average, earn more money and obtain higher levels of education than the native white populations (Bhattacharyya, Ilson, Blair, 2000). According to the London daily times (January, 23, 1994, as reported in Stringer and McKie 1997:190; Re-reported by Smedley in Lieberman 2001:p87) “Black Africans have emerged as the most highly educated members of British society, surpassing even the Chinese as the most academically successful ethnic minority.”
In the U.S. Black immigrants from Africa average the highest educational attainment of any population group in the country, including whites and Asians (See Logan & Dean, 2003).
- Brains -
Tobias (1970) listed a number of difficulties involved in measuring and making meaningful comparisons of brain weight. These included equating subjects on age, sex, body size, temperature etc. In addition, brain development is plastic, and brain size may be affected by early environmental factors. Because of all these difficulties, Tobias (1970) concluded that no adequate racial comparative studies had actually been conducted.
Interestingly enough, the brain size of American blacks reported in Tobias’s summary were larger than any white group, (which include American, English and French whites) except those from the Swedish sub sample (who had the largest brains of any of the 77 national groups measured), and American blacks were estimated to have some 200 million more neurons than American whites (See Tobias 1970; Weizmann et. 1990).
Ironically, many of the racial researchers of today who make claims about racial differences in brain size cite Tobias (1970) as one of their main sources while ignoring the findings reported in his work; I.E. Blacks on average had larger brains than virtually all other population groups!
The main correlation with brain size is height/size; because of this the average black/white brain is certainly larger than the average Asian brain (not proportionally, but in Absolute terms). Witelson’s, Kigar’s and Thomas’ (1999) examination of Albert Einstein’s brain illustrates that something more complicated than a brain’s size relates to it’s owner’s intelligence. They compared Einstein’s brain with an average specimen from a sample 35 intact, control brains. Einstein’s brain has about the same dimensions and the same weight as the comparison brain. However, in areas specific to Einstein’s unique skills, his brain was quite different. This leads one to conclude that it is overall brain structure and not brain size that determines one’s intellectual strengths.
If you are interested in learning about the nature and nurture of brain development I suggest researching the work of Joan Stiles (Developmental Cognitive Neuroscientist, UCSD).

- IQ -
There is also research that shows people with higher IQ scores to be lacking in skills relating to Practical Intelligence (See Sternberg 2001, and 2004). That is, IQ and Practical intelligence skills correlate negatively. Further, Sternberg demonstrates that tests of Practical intelligence are better at predicting job performance and real world success.
Leon J. Kamin (Bell Curve Wars, 1995 p.92): “Extensive practice at reading and calculating does affect, very directly, one's IQ score.”
Race, Genetics and IQ:
- A study conducted by Tizard and colleagues involving Caribbean children showed that there was no genetic basis for IQ differences between black & whites. The IQ of the children at the Orphanage was: Blacks 108, Mixed 106, and White 103 (James R. Flynn, 1980. Richard E. Nisbett, 1994. Also see, The Bell Curve wars, 1995).
- IQ differences in the U.S. are not as drastic as some would have you believe. Many researchers put the difference between 7-10 points (Richard Nisbett, 2005; Vincent, 1991; Thorndike et al, 1986; Leon J. Kamin, 1995; Dickenson & Flynn, 2002). As well, this conclusion is only reached after lumping the entire black population together as a single body. The truth is blacks from different regions in the U.S. differ markedly in culture and achievement.
- In more than a dozen studies from the 1960s and 1970s analyzed by Flynn (1991, 2002), the mean IQs of Japanese- and Chinese American children were always around 97 or 98; none was over 100. These studies did not include other Asian groups such as the Vietnamese, Cambodians, or Filipinos; who tended to under perform academically and on conventional psychometric tests in contrast to the former groups mentioned (See Flynn, 1991).
- Adjustments for socioeconomic conditions almost completely eliminate differences in IQ scores between black and white children. Co-investigators include Jeanne Brooks-Gunn and Pamela Klebanov of Columbia's Teachers College, and Greg Duncan of the Center for Urban Affairs and Policy Research at Northwestern University.
- Osbonre and Suddick (1971, as reported in Loehlin, 1975) attempted to use 16 blood-groups genes known to have come from European ancestors. Testing two samples the authors found that the correlation
