in every test using the SAT alone does better in aggregate.
This is emphatically wrong. From the most pro-SAT source I can think of, SAT's + High School GPA are the most accurate predictor of first-year grades available. I admit the possibility that if you use a different measure of college success, my point is not valid.
It may be comforting to overstate the value of standardized testing, but that does not make it true, or excuse unfounded generalizations. One should be particularly careful to avoid such generalizations in a blue-green issue like the value of intelligence testing.
I think billswift's point was that the SAT is a better predictor as opposed to using human judgement as in reading the application letter, etc... It seems plausible that adding another "objective" measure like the HSGPA will further increase accuracy. But the big point is that using human judgement will DECREASE accuracy. The really interesting paper is the following as suggested by Alicorn:
Michael Bishop, "In Praise of Epistemic Irresponsibility: How Lazy And Ignorant Can You Be?"
I stumbled upon an article called The New Nostradamus, reporting of a game-theoretic model which predicts political outcomes with startling effectiveness. The results are very impressive. However, the site hosting the article is unfamiliar to me, so I'm not certain of the article's verity, but a quick Google seems to support the claims, at least on a superficial skimming. Here's his TED talk. The model seems almost too good to be true, though. Anybody know more?
Some choice bits from the article:

Gets good money for it:
The method should be of special interest to the OB/LW audience, as it brings to mind discussions about self-deception and evolutionary vs. acknowledged goals and behavior:
