How to Guess Better on an SAT

A nice analytic giblet from a Times profile of new Nobel economists Thomas Sargent and Christopher Sims:

Because of his father’s College Board connections, Mr. Sims got hold of an old SAT exam, which he and Mr. Willoughby used to conduct a statistical analysis. They found that on multiple-choice questions in English and social studies, the “longer answers tended to be correct.” In math, they determined that the number that was “closest to all of the other numerical choices” was probably the right one.

I do wonder if those patterns still hold true in standardized tests. Of course, you can always pay someone else to take the test for you.
