IQ and social class/wealth

A recent BBC news article is claiming that the Working Class have lower IQ scores on average than the middle class of Britain.

The scientist claims that this is due to inherited difference, but does not even consider any of the environmental differences between the working and middle class that affect IQ. Working classes have a much lower usage of private schools and usually live in areas of worse state schools, so have lower quality education and mind training in the thought needed to do well in IQ tests. It failed to mention that wokring classes have a worse diet than middle classes often with more E numbers and artificial colours and more fat and less nutrients and vitamins. Working classes are more likely to have absent parents and increased nutrure has been shown to increase IQ. Middle classes are much more likely to have Academic parents who engage their children in more thought and convesation that develops IQ test skills. Fighting and head injuries are more common among working class boys and lads aswell which will further lower their average IQ.

Yet more evidence of a scientist trying to make a name for himself, or less likely a scientist with class prejudices.
