The cracked Bell Curve.

A controversial book called "The Bell Curve " claimed to prove a link between race and IQ but it failed to address the relationship between education, family background and IQ. For every year of education beyond the eighth grade the IQ can increase 2 to 4 percent (23 ).

IQ can change and don't seem to be tied to genetics. Adopted children can have the same IQ as their biological parents. But the average IQ of adopted children is higher than that of their natural parents (24 ).

IQ can change, experts tracked children who came from abusive homes, impersonal institutions, multiple foster care placements and etc. nine years after they were adopted all their test scores improved. The most improvement was with children who were adopted by affluent Families ( 25 ).

IQ averages for races can change. In 1920 Chinese ranked lower than blacks are today. Now the average Chinese IQ is higher than blacks (26 ).

A study of white and black children's IQ said "IQ differences between black and white children are almost completely eliminated by adjusting for differences in neighborhood, economic conditions, family poverty, maternal education and learning experiences," (27 ).

Also the worldwide IQ has risen 15-20 points since 1950 (28 ).

IQ success and intelligence


A common trait of successful business people and people in politics is mediocre school and test performance. Workers with lower IQ tended to score lower when tested on Job knowledge. But the difference disappeared with job performance (29 ).

Research by National Longitudinal Survey of Youth found no relationship between a High IQ and wealth. "People don't become rich just because they are smart. Your IQ has really no relationship to your wealth. And being very smart does not protect you from getting into financial difficulty," said lead author Jay Zagorsky (30 ).

A final word on intelligence, intelligence is a word used by psychologist and others to define behaviors in certain context. A task force for American Psychological Association, "Because there are many ways to be intelligent, there are also many conceptualizations of intelligence's"(31 ).

Race and health

Is one race genetically more healthy than the others? Though some diseases tend to concentrate on certain races, no race is free of diseases. the "Celtic gene" makes Scots more likely to get Multiple Sclerosis (32 ).

Sickle cell anaemia effects mostly people of African and Asian decent (33 ).

Cystic fibrosis affects mostly Caucasians of west and central European ancestry (34 ).
