What Does the SAT Test? (2004)

(The formula seems suspicious, though -- 800 math, 800 verbal converts to an IQ of 129, and 500 math, 500 verbal, which is supposed to be the average college-bound student, converts to 99. The average college-bound student should have an IQ higher than the average person.)
It tests the smaller of two things: your test-taking ability and your "knowledge." "Knowledge" in this case is what you have learned and retained through high school. I am being gracious by throwing test-taking ability in there, because I'm not entirely convinced there really is such a thing. I only took the ACT once, as a senior, and scored a 32 (out of 36), so I certainly hadn't specifically prepared for the type of test. I just took the test, and the questions I knew the answers to, I got right, the others I got wrong. But since almost everyone else seems to agree that being bad at test-taking can make you "choke" and score lower than what you should, I will concede that your ACT test score represents the lower of those two attributes.
We are developing SAT prep apps for iPhone, desktop and web and I believe that people can score higher if they practice a lot which is not true for an IQ test IMO.
If you had the same access to the item content of IQ tests that you have to the item content of the SAT, you could definitely develop an IQ test-prep application of similar effectiveness.
One paragraph in the submitted article caught my eye, because it reports an opinion I had previously found in another set of sources: IQ tests correlate strongly with the SAT because both primarily tap scholastic ability (as contrasted with "general intelligence"). Who says this? Lewis Terman said something much like this when discussing the second major version of his Stanford-Binet IQ test:
" There are, however, certain characteristics of age scores with which the reader should be familiar. For one thing, it is necessary to bear in mind that the true mental age as we have used it refers to the mental age on a particular intelligence test. A subject's mental age in this sense may not coincide with the age score he would make in tests of musical ability, mechanical ability, social adjustment, etc. A subject has, strictly speaking, a number of mental ages; we are here concerned only with that which depends on the abilities tested by the new Stanford-Binet scales." (Terman & Merrill 1937, p. 25)
Julian Stanley, the founder of the Center for Talented Youth at Johns Hopkins University,

and probably personally acquainted with more young high scorers on the SAT than any other researcher until very recently, long ago noticed that IQ tests tap mostly scholastic aptitude.
"The Binet scales and their descendants are perhaps the most publicized accomplishments of modern psychology. The term IQ, though often misunderstood, is a household word. The practical success of the 'IQ test,' in its ability to place individuals along a spectrum of scholastic aptitude from dull to bright and in its relationship to school and occupational success, has overshadowed doubt about what the tests were measuring in an exact, psychological sense." (Hopkins & Stanley 1981, p. 348).
"Most authorities feel that current intelligence tests are more aptly described as 'scholastic aptitude' tests because they are so highly related to academic performance, although current use suggests that the term intelligence test is going to be with us for some time. This reservation is based not on the opinion that intelligence tests do not reflect intelligence but on the belief that there are other kinds of intelligence that are not reflected in current tests; the term intelligence is too inclusive." (Hopkins & Stanley 1981, p. 364).

You certainly are far from alone in that opinion. What would you suggest that colleges look at rather than SAT scores when choosing from a larger number of applicants than the colleges can offer admission to?
i'd really like a college to sit down and do a study on what really does predict success in their student body, looking at and perhaps requiring different things like IQ, SAT, ACT, high school data, etc.. test all incoming freshmen on the things they haven't already taken. etc.
Edit: My point being, even if IQ and SAT are correlated, I suspect there are a large number of intelligent people for which test does not correlate. i.e. p < 1
You also imply that there is a single 'motivation' scale. There isn't. I am highly motivated at my startup and many other things. I'm highly unmotivated at answering the same math problem for the third time with different numbers.
Just consider how differently teenagers mature and how that might affect their learning. Lots of them do sports instead of reading. A friend of mine never studied in school because she had an unknown eye problem; new glasses at 30 and she could read effortlessly. Some are depressed or suffer unknowingly from a disease. Etc.
Edit: As noted, I should have written "any researcher in the subject" instead of "anyone" in the first sentence. :-)
Certainly no professional psychologist would claim that IQ tests have no error of estimation.
