Being good at a set of abstract formal rules is probably at least some kind of indicator that you'll be good at another set of abstract formal rules.

Having recently taken a battery of psychological tests that measure several different cognitive functions, I am one living example that that is not the case.

How can you be an example that what I said "is not the case"? Are you saying that because you are not similarly good in two different sets of abstract formal systems, that this isn't a good indicator in general?
