Scientists knows that IQ is not a perfect measurement device for "intelligence". No test will ever be able to put accurate numbers on anything resembling the ill defined quantity "intelligence". So IQ test scores will never be anything more than just something which correlates with intelligence, but correlation is good enough for most statistical needs.chiro said:When the scientists have a less broad and less naive version of intelligence, only then will I start to pay attention to what IQ scores represent but quite frankly I don't see that coming about any time soon.
But it is the same as with everything else, your high school grades don't tell you how well you will do in college, it do however correlate with success in college which is why it is used as a way to differentiate between applicants. I am sure that there are plenty of cases of person A and B where person A with score 3.0 would perform better academically than person B who has 4.0, but we got nothing else to go on so the guy with 4.0 gets the spot.
It isn't scientists who overemphazise IQ btw, it is the laymen who thinks that IQ is intelligence and things like someone with 200 IQ would be able to factorize 6 digit numbers in seconds. And physics majors etc don't see themselves as geniuses, they do however see those who studies something else as people taking the easy way out since the material is easier and they often have better job prospects. Thinking that studying physics makes you a better person is a psychological defense mechanism to ward off psychological attacks of the form "Why don't you study business? It would be less work and more pay!".
