What about studies equating race with intelligence?
Scientific work abetting the idea that race is real, typological, and hierarchically arranged is actually rather an old occupation, you know. In the mid-1840s we see Samuel Morton measuring crania to get at cranial capacity and then to try to rank the races on the amount of cranial capacity they have, and to equate that with racial differences and intelligence.
And really about every 20 years somebody else comes along, almost with a best-seller, perhaps with a new method for measuring intelligence, ultimately to show that there is a ranking in intelligence, usually with whites up top.
The most recent effort was The Bell Curve, which came out in 1994 and literally reached number two on the best-seller list in 1994, behind a book, by the way, written by Pope John Paul. The Bell Curve threw a couple spins into this. One is that it actually promoted Asians as being closer to the top, also broke down whites a little bit more. But fundamentally it was the same type of book as was written by Morton in 1850; you use the same basic methods and the same basic logic.
Their argument went something like this: there is something called intelligence that we can put our fingers on, that we can measure; intelligence is some sort of univariable; it’s one-dimensional. That intelligence then is measurable by something called an intelligence test that actually measures intelligence. And then that intelligence is highly heritable; it’s something we really do get in our chromosomes, in our genes; it comes to us that way, it is highly heritable. Then one has to say that there is such a thing as white, black, and Asian, or whatever groups you’re comparing, that they are real, that they are measurable, that they are reproducible.
But then let’s to back and look at the assumptions again. Is there a white group, a black group, an Asian group? Are these reproducible? Are they trained equally? Can we really measure a variable called intelligence? Is it really something that’s not affected by environment, about how we’re trained, how we grow up, what stimulation we have by children?
I’ll give you an example. One test has shown that just a little bit of lead in the blood can affect intelligence - a little bit of lead in the blood, prenatal, can affect intelligence by easily eight points on an intelligence score. Are we to believe that those factors were unimportant in looking at the differences in IQ scores? Of course not.
The assumptions that go into believing that there are racial differences in intelligence are absurd ones. They’re ones that we shouldn’t even be coming close to as scientists. The chief one is that here’s such a thing as race, that there are races, and that a score on a test, an average group score, has any meaning for an individual.
