No, it is an established fact blacks score lower on their SAT's because they can't afford to pay someone to write them for them, like many well to do people from Shaker Heights and Forest Hills apparently can.
It is absolutely uncanny how IQ scores increase dramatically amongst the very well to do and upwardly mobile, desperately in search of C's. Why I would estimate the IQ of scions of the rich is ensconced at a mean whose scores amongst that in the hoity toity averages 90th percentile. The bottom of society, not having been steeped in the culture of the dire necessity of paper on the wall for status, have not yet discovered the greatest test of intelligence of all. The art of socially organized widespread cheating and bribery. It has been estimated that the graduating class of Texas A&M had, in any one year, purloined exam secrets to the tune of 65% of the class. But for the Bell curve, the Soviets, apprised of these test scores of impending genii, would have gracefully conceded defeat in the cold war, knowing all too well the impossibility of competing with a race of superheros.
I used to save the exam questions on my father's 1934 final engineering exams from a small college in Ontario, Malvern. In addition I apprised myself of some of the basic questions of Faraday, Carnot, Archimedes, Pascal, and a few others. Things like the photo-electric effect, thermodynamics of a combustion engine (efficiency formula,) Gibbs paradox, basic theorem of integral calculus, etc. So I would sidle up to 4th year science and engineering students and ask innocently over french fries with the eager look of a freshman, "so what is a (magnetic) field anyway?" Or, how would you establish which substance glowing red was hotter, a piece of steel, or wood? So how does a magnet manage to pull a piece of iron when there is nothing attached to it, or no medium? How would you establish a critical mass of some U235? Or the piece de resistance, "which is more theoretically efficient, the steam engine or the diesel and why?" Well amongst the scientific leaders of tomorrow, you could collect blank looks to fill a high school yearbook of mugshots. And wrong answers. Dead wrong, I am afraid. Every time. At least the girls would say, "I don't know." You might be able to educate them. (BTW, that is the correct answer to many questions. You could add, and no one will ever know too.)
The smartest people I ever met, were a chick who put herself through U of T on scolarships in order to learn to write, a drug addict, a non graduate self taught computer programmer, an undergrad progamming student from Jamaica, and a relative who used to assist a nobel prize winner. Smarts seem to be evenly divided in my life between the sexes, and races incidentally. Fair number of mathematical pakis. So many that they should have a category for them. Arithmopakis. Abilities are also all over the map, and I don't credit linear symbol recognition ability as the best arbiter of worth. Abilities seem to vary with people. Some seem to see things in visual patterns, others are numbers people, some work well with their hands, others push clouds of ideas and are very theoretical. I cannot measure the ability of people to paint a picture, or make music, act, other than in the doing of it, which in the end is what counts.
Finally, the ability of people to cheat co-operatively may be an important social survival skill and I should not make value judgements about it.
