James Watson says some controversial things
He says that he is “inherently gloomy about the prospect of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours - whereas all the testing says not really” …
This quote does not seem entirely representative, but it's what everyone else is quoting, so I'm inclined to share my opinion.
Watson does goes on to say some (to my mind) obviously racist things, but I don't think that the extract above is necessarily wrong. IQ tests are inherently biased to a certain form of thinking; they favour such a narrow niche that being white, male and middle-aged gives one a pretty solid advantage, statistically speaking. The important thing here is that there are different types or forms of intelligence, and IQ measures only one such shape.
I think (as alluded to before) that half of Africa's problems stem from this expectation that they can act like civilised white men if we just give them a chance. I don't see this happening – not because they are inferior in any way, but because we are not all the same. The world would be a far better place if we stopped pretending that ours was the one superior form of ‘civilisation.'
