I have not followed this thread with perfect attention, so forgive me if I misunderstand any of the points you're making. > Are you sure they are ahead?

Certainly a 20 month old being able to line up 20 toys and count them does not imply the child has Fermat's facility for number theory, as it certainly is largely memorization, but IIRC I was learning to count on my fingers when I was in kindergarden (OK, so I'm not Gauss :-), although I did figure out division on my own a few years later), so I still think the achievement level of younger people says something worth noting. Is it "intelligence"? If it isn't, it is at least a building block that is needed for the quantitative reasoning portion of intelligence. > As for "full blown > calculus", knowing all the methods of computing derivatives > and antiderivatives in closed form provides NO understanding > of what any of it means.

No doubt your concerns have some validity, but there are levels of understanding, especially in math, and I'm not willing to say that only the highest level of understanding is the one that exclusively counts in the IQ or education debate. If a high school students can recognize the calculus to apply to a problem and apply it correctly, that still allows them to solve problems I couldn't in the same grade, even if my understanding of fundamental mathematical concepts was better (which it may or may not have been). A person can make intelligent use of, say, calculus without being able to derive the properties of the real number system from first principles, formally or informally. If a person can do this at the level I attained as, say, a freshman in college when he/she is a junior in high school, then IMO that person is, for practical purposes, two years smarter than I was. Again, if this isn't germane to the argument your making, feel free to ignore my ramblings.
