I don't have a link handy, but hopefully someone else does. There is some thought that there are bubbles at both end of the normal bell curve. There certainly seem to be more children out at the right end of the curve than we'd expect statistically.

At any rate, we probably should not talk in terms of those old IQ numbers because it is confusing as there are no accurate current tests that use that scale and no real way to differentiate that through IQ testing.
