Thanks. That was good. I found it interesting that black IQ tests have names like BITCH or S.O.B...but not as interesting as this: footnote: *** In a 1973 university study of intelligence test outcomes, J. Mercer (UCBerkley) found that 300% more Mexican Americans and 50% more Blacks were labeled as mentally retarded than would be statistically possible. Labeling the Mentally Retarded, University of California Press.

The links were mostly of little interest, but this interesting table was there. <But does it? Similar to Fallows, Crouse and Trusheim more recently noted the continuing differences in SAT scores along class lines The clear correlation between SAT scores and social class did not escape Ralph Nader and Allan Nairn, who said, "If ETS scores really measure an important aspect of a person's 'merit' or, as ETS specifically calls it, 'scholastic aptitude', then merit in the United States is distributed according to parental income" (Nairn et al., 1980, p. 204). SAT range Mean family income upper 1600...........$14,400 1500...........$16,300 1400...........$15,300 1300...........$15,200 1200...........$14,700 1100...........$14,200 1000...........$13,700 900.............$13,200 800.............$12,700 700..............$9,500 600..............$9,300 500..............$5,000 > I rounded the dollars. From that we can see the value of brains. We can reasonably assume that SAT results are much the same as the parental SAT results. So those in the bottom quarter, earned something like $10,000 while those in the op quarter earned something like $15,000. It's worth 50% more income each year to have a turbo-charged brain. Not even turbo-charged really, just better than average rather than worse than average. With that 50% saved and invested each year, after 20 years or working, saving and investing, you can imagine, even without doing the compounding thing, that the smart ones will have enormously more value than the duller. Brains really are extremely valuable. Heavy taxation on the productive conceals just how valuable intelligence is. It compares reasonably well with my calculation of the value of IQ 20 years ago when I was involved with lead in petrol and the consequences of pollution [during my time with BP Oil]. The destruction of brains by lead was about a quarter IQ point in heavily motorized countries and the benefits were small [if any] compared with the cost of the damage. Lead in petrol was one of the great blunders of the 20th century. I'm surprised there hasn't been a class action suit against the lead polluters. The asbestos damage was small by comparison, though very bad for the individuals concerned. In lead poisoning, everyone suffered a small amount of damage, compared with asbestos poisoning which caused fatal damage for a few individuals. Mqurice
