bpesta22; said:We must be reading different literatures. Even the APA conceded that IQ and educational achievement are strongly related (.5 for gpa; .55 for years education) and conceded that no environmental intervention has been capable of raising IQ in the long run.
If it interests you and doesn't seem like a derail, please cite some studies showing that education increases one's IQ (I'd argue the cause goes the other way).
I'd have to dig it up, but I remember reading a study where IQ predicted grades after controlling for ses, but ses no longer predicted grades after controlling for IQ.
The key controversy surrounding intelligence testing, Quiñones says, is whether the tests measure innate ability or acquired knowledge. If they test innate ability as some claim, does that mean intelligence is unchangeable?
The notion that mental ability is largely genetic and can’t be improved has come under serious attack.
In fact, scholar James Flynn has shown that IQ scores in the Western world have increased by 15 points in one generation. The political science professor from New Zealand’s University of Otago also has concluded that Americans of the 1970s were 22 points smarter than Americans of the 1890s.
Another criticism of IQ tests is the self-fulfilling prophecy issue. Claude Steele, a psychologist at Stanford University, has shown that people who are expected to score low generally will do so. Black students in particular, he says, suffer from what he calls “stereotype vulnerability.” But Steele asserts that stereotype vulnerability is not limited to blacks. He once gave a group of white students a math test and told them that Asians tended to do better on it than whites. The result proved his point. “That may be enough of a reason to say that labeling someone early is not an appropriate thing to do,” Quiñones suggests.
A third issue is whether intelligence tests measure an innate core of mental ability known as general intelligence. Some studies have shown that people who score well on a mathematics test will probably do well on vocabulary. “Some people have taken that as evidence that there is a general level of intelligence that underlies all mental abilities,” says Quiñones. Opponents of this view say that there are many dimensions to intelligence and that IQ tests are not broad enough to measure abilities such as musical and mechanical talents. “The multiple intelligence view appeals to people’s sense of fairness,” notes Quiñones. “They can say, ‘Oh, Johnny may not be so smart in math, but he’s one heck of a violinist.’”

There's all sorts of problems with IQ tests. You can accurately measure the SES status of a preschooler, but measuring the preschooler's IQ is much harder., if it even has any validity at all. Children in head start programs test better on evalutations such as the Naglieri Nonverbal Ability test, but that doesn't mean the child is smarter.
