Well Mathew, I see your logic but what I see the Op is also pointing out and that your logic doesn’t address. It's that there are many forms of intelligence that form a holistic human where as our modern society doesn’t value them with an appropriate balance and focuses it’s attentions and valuation on a few. This out of touch valuation has many of them undiscovered by many of us. In other words, we tend to disbelieve in them as intelligences and therefor we don't understand ourselves because we are not looking with the correct eyes to see...

I found this little test about a year ago and found what it suggests very interesting.
The accuracy of the test is not the point of taking it. But the suggestion of there being more than, and or more relevant than previously thought aspects of our intelligence than our modern outlook affords us on average.
