<p>I’m sorry, perhaps I was unclear. Statistical correlation was 0.483, SAT scores with Raven’s Advanced Progressive Matrices (see Figure 1). They had to correct that to 0.72 due to restricted range, but the correction was calculated, not obtained. The data points you refer to are correlations between the ASVAB and SAT (again, see Figure 1). Note that the ASVAB is NOT an intelligence test but rather a test of acquired knowledge. The ASVAB is more similar to the SAT than to any administered IQ test. In fact, Mensa, the high IQ society, will not even accept the ASVAB as a qualifying standardized test! I find it perplexing and ultimately untenable that Frey and Detterman chose to correlate ASVAB and SAT as a measure of intelligence. </p>
<p>Again, the SAT does not test anything that is innate. It tests on material that is taught. Hence, the tailored secondary school curriculum and prep books. If it tested on something that was innate (i.e. intelligence), you wouldn’t be able to prep for it because you cannot change something that is innate. Differences in scores in students who have not prepped for it is a reflection of differences in their school curricula and socioeconomic background. Practicing a Weschler test also would not get you far. That test tests on something that is not taught and cannot be taught. It’s like athleticism. You can’t teach speed.</p>
