Speaking as one who’s abilities lie in the of middle of the Bell Curve
I can forgive to some extent the lack of social graces and arrogance that some intellectual heavyweights display (even though they should know better) but only if they can deliver.
Many pseudo-intellectuals think that they are in the genius category
But “when push comes to shove” are unable to deliver the goods and us lesser mortals are left to pick up the pieces.
