Inasmuch as all the discussions about IQ, and especially IQ of 90 preparing for the SAT, are interesting and perhaps entertaining, most of it seem grounded in generalities that are quite distant from the “discovery” of Murray.
If one can easily agree that various of intelligence or, if you prefer, pragmatic smarts that take the form of reasoning, end up playing an important role in the SAT scores, are we still in agreement that the correlation between SAT scores is with … the mother’s IQ? I assume that with the upcoming release on March 30 of the exact text, some might want to read the “research” to redefine their conclusions, and especially after looking into the data used to establish the correlation.
As far as the preparation versus brute IQ (or aptitude, my own conclusions based on a reasonable amount of data is that most people are UNDERSCORING their natural abilities. While an adequate preparation cannot extract blood from a turnip, it can help a student reach the highest level of his or her own abilities.
It is also good to remember that the preparation for the SAT differs greatly among participants. Some students can do extremely well after simply getting familiar with the format of the test, and especially if they have some history with testing (think AOPS or years of having to submit to the ERB ordeals) or are avid readers and puzzle solvers. Others benefit from the repetition brought by a heavy dose of practices.
The real question remains … what is there to be done if the SAT or its bastard cousins tests do really correlate to wealth, income, IQ from the mother, or the cost of pets in the household? Do we need to abolish the test that “confirm” or “underscore” the great inequalities in our education system? Do we really need more wasted inks to know that the rich, the smart, the intelligent, and the lucky attain higher level of education or SES than their poorer fellows?
Do we really need people like Murray, who has flip-flopped his positions depending on the conclusions he wants to reach at the time, to muddy the waters with findings that border on the inconvenient or obscene?
What we need is for people to develop solutions that have a chance to work. And, fwiw, since we can’t pick our mothers, and since it is seems that having a decent level of education throughout the US remains a pipe dream, the low hanging fruit is none other than … preparing for the tests and stop complaining about it.
