Obviously Callista you say the true. But for any preliminary statistic you need to reduce the number of possible variables, also I think that basically at least 20-30% of people here have taken a general IQ test, while more specific tests are less taken.
I've a similar scatter to you: basically perfect 3d visualization (I full the scale in any test I take), good fine motor skill, poor gross motor skill. Far higher in the matrix/spatial/mathematical part than on verbal component. Below average EQ (empathic quotient) but very scattered (very low interpersonal, very high intrapersonal).
I find also very interesting the distintion between intrapersonal-interpersonal intelligence with an eye on autism, I think many of us will present that kind of scatter.
General IQ test still activate only 6% of our brain (with general I mean a test with: matrices, rotation, mathematical series, verbal analogies, etc.. all together).
I also agree that the infamous "g-factor" (general intelligence) is somewhat correlated between 0.6 and 0.9 with IQ tests (depends on the test) but the correlation is far lower for autistics. But we don't have other "1 score take it all" instruments at the moment, at least not enough widely used.
