I like this idea.
I suppose it’s a tradeoff from optimum functioning to directed specialization.
The genetically well-endowed (good structure) needn’t apply it to anything special. That’s the special in specialization, and as much as I abhor the modern over-reliance on it, there it is right within the word, bold yet demure.
And it is the latter character where the Great Geniuses are to be found, as in their case, there is likely something to overcome (average or below-average structural bequeath). Is this why we respect them more than the high IQ with great, yet unfulfilled potential?
