Continued ” So it is that we came to think of real intelligence in terms of logical analysis: believing that rationalist forms of thinking were superior to feeling and emotion, and that the ideas that really count can be conveyed in words or through mathematical expressions. In addition, we believed that we could quantify intelligence and rely on IQ tests and standardized tests like the SAT to identify who among us is truly intelligent and deserving of exalted treatment.
Ironically, Alfred Binet, one of the creators of the IQ test, intended the test to serve precisely the opposite function. In fact, he originally designed it (on commission from the French government) exclusively to identify children with special needs so they could get appropriate forms of schooling. He never intended it to identify degrees of intelligence or ‘mental worth.’ In fact, Binet noted that the scale he created ‘does not permit the measure of intelligence, because intellectual qualities are not superposable, and therefore cannot be measured as linear surfaces are measured.’
Nor did he ever intend it to suggest that a person could not become more intelligent over time. ‘Some recent thinkers,’ he said, ‘[have affirmed] that an individual’s intelligence is a fixed quantity, a quantity that cannot be increased. We must protest and react against this brutal pessimism; we must try to demonstrate that it is founded on nothing.’
Still, some educators and psychologists took – and continue to take – IQ numbers to absurd lengths. In 1916, Lewis Terman of Stanford University published a revision of Binet’s IQ test. Known as the Stanford-Binet test, now in its fifth version, it is the basis of the modern IQ test. It is interesting to note, though, that Terman had a sadly extreme view of human capacity. These are his words, from the textbook The Measurement of Intelligence: ‘Among laboring men and servant girls there are thousands like them feebleminded. They are the world’s “hewers of wood and drawers of water.” And yet, as far as intelligence is concerned, the tests have told the truth . . . No amount of school instruction will ever make them intelligent voters or capable voters in the true sense of the word.’
Terman was an active player in one of the darker stages of education and public policy, one there is a good chance you are unaware of because most historians choose to leave it unmentioned, the way they might a crazy aunt or an unfortunate drinking incident in college. The eugenics movement sought to weed out entire sectors of the population by arguing that such traits as criminality and pauperism were hereditary, and that it was possible to identify these traits through intelligence testing. Perhaps most appalling among the movement’s claims was the notion that entire ethnic groups, including southern Europeans, Jews, Africans, and Latinos fell into such categories. ‘The fact that one meets this type with such frequency among Indians, Mexicans, and Negroes suggests quite forcibly that the whole question of racial differences in mental traits will have to be taken up anew and by experimental methods,’ Terman wrote.
‘Children of this group should be segregated in special classes and be given instruction which is concrete and practical. They cannot master, but they can often be made efficient workers, able to look out for themselves. There is no possibility at present of convincing society that they should not be allowed to reproduce, although from a eugenic point of view they constitute a grave problem because of their unusually prolific breeding.’
The movement actually managed to succeed in lobbying for the passage of involuntary sterilization laws in thirty American states. This meant that the state could neuter people who fell below a particular IQ without their having any say in the matter. That each state eventually repealed the laws is a testament to common sense and compassion. That the laws existed in the first place is a frightening indication of how dangerously limited any standardized test is in calculating intelligence and the capacity to contribute to society.
IQ tests can even be a matter of life and death. A criminal who commits a capital offense is not subject to the death penalty if his IQ is below seventy. However, IQ scores regularly rise over the course of a generation (by as much as twenty-five points), causing the scale to be reset every fifteen to twenty years to maintain a mean score of one hundred. Therefore, someone who commits a capital offense may be more likely to be put to death at the beginning of a cycle than at the end. That’s giving a single test an awful lot of responsibility.
People can also improve their scores through study and practice. I read a case recently about a death row inmate who’d at that point spent ten years in jail on a life sentence (he wasn’t the trigger man, but he’d been involved in a robbery where someone died). During his incarceration, he took a series of courses. When re-tested, his IQ had risen more than ten points – suddenly making him eligible for execution.
Of course, most of us won’t ever be in a situation where we’re sterilized or given a lethal injection because of our IQ scores. But looking at these extremes allows us to ask some important questions, namely, What are these numbers? and, What do they truly say about our intelligence? The answer is that the numbers largely indicate a person’s ability to perform on a test of certain sorts of mathematical and verbal reasoning. In other words, they measure some types of intelligence, not the whole of intelligence. And, as noted above, the baseline keeps shifting to accommodate improvements in the population as a whole over time.
Our fascination with IQ is a corollary to our fascination with – and great dependence on – standardized testing in our schools. Teachers spend large chunks of every school year preparing their students for statewide tests that will determine everything from the child’s placement in classes the following year to the amount of funding the school will receive. These tests of course do nothing to take the child’s (or the school’s) special skills and needs into consideration, yet they have a tremendous say in the child’s scholastic fate. ”
