You know, test a subject to determine where their skills end, then measure what it takes to add to those skills?


All mental/cognitive tests measure something called the g factor. It is the general factor of such tests. It has proved impossible to make a such test that does not correlate positively with all other tests, altho sometimes only slightly.

What you are referring to is what is often called fluid intelligence, or gfluid. It is as opposed to crystallized intelligence. This distinction is important wrt. aging and cognitive ability because the fluid-type ability declines faster. Basically, as you age, you decrease in the ability to take part in abstract, analytic thought. However, you generally retain the information you have already and even increase it despite some loss due to faulty memory. The increase is faster than the loss up to a certain point, usually around age 60 (on average).

Perhaps read some introductory material. Here's a collection I made: http://emilkirkegaard.dk/en/?p=3034
