We All Share The Intelligence Gene
The least smart among humans are actually really smart. Really smart in many ways.
Conversely, the smartest among humans are actually really ignorant. Really ignorant in many ways.

This assessment does not include those at either end of the intelligence spectrum/continuum who are considered challenged by handicap.
However even at the most extreme ends of said spectrums, those thusly challenged display enormous feats of comprehension when not standardized into test formats.
