Proof niggers are dumb (IQ, brain size etc)

Oriental populations in East Asia and North America typically have mean IQs falling between 101 to 111. White populations in Europe, South Africa, Australasia, and North America have mean IQs of from 85 to 115, with an overall mean of 100. Black populations living south of the Sahara, in the Caribbean, in Britain, and in North America, average IQs of from 70 to 90.

Especially contentious was Lynn's calculation of a mean IQ of only 70 for Black Africans living south of the Sahara. Many reviewers have expressed skepticism about such a low IQ, holding it impossible that, by European standards, 50 percent of Black Africa is 'mentally retarded'. But a mean African IQ of 70 has been confirmed in three studies since Lynn's review, each of which used Raven's Progressive Matrices, a test regarded as an excellent measure of the non-verbal component of general intelligence and one not bound by culturally specific information.

You guys are completely full of shit.

First off, IQ doesn't directly relate to future job prospects.  Education helps, but not as much as having the skillset your boss actually wants.  Even then, many people do get on very well without multiple degrees or any higher education at all (especially the skilled trades like HVAC (the guy who fixes your air conditioner), electricians, carpenters, etc.  If fact it's somewhat common and even cliche to find a person with degrees (up to pHD in some cases -- and you can't get a pHD with an IQ of 70-) how work essentially dead end jobs. 

Secondly, the IQ test is based on an outdated model of intelligence.  The test measures your ability to do basic mathematical skills and skill with analogies.  That isn't the definition of intelligence.  Intelligence is the ability to adapt to a new situation, to come up to a problem that you've never seen before and figure out the solution.  The test measures specific skills, and moreover, the more you practice those specific skills, the better you get.  Just like any other set of skills. 

This is one of the big problems that AI runs across.  You can "teach" a computer AI specific skills, but even if a computer can learrn from mistakes, it can't adapt to a completely new situation.  Big Blue can learn how to play a great chess game.  It wouldn't have a clue about even a simple game of monopoly unless the machine was reprogrammed.  It would fail at Halo for the same reason -- you're asking it to adapt to a new situation without first telling it exactly what to expect.  So even if I could program a computer to ace any IQ test I throw at it, that doesn't mean that it's intelligent, just that it has that particular skill.
