<<<Many traits in many species have evolved through sexual selection specifically to function as fitness indicators that reveal good genes and good health. Sexually selected fitness indicators typically show (1) higher coefficients of phenotypic and genetic variation than survival traits, (2) at least moderate genetic heritabilities and (3) positive correlations with many aspects of an animal's general condition, including body size, body symmetry, parasite resistance, longevity and freedom from deleterious mutations. These diagnostic criteria also appear to describe human intelligence (the g factor).>>> (from abstract).

So then, is there some sort of mirror neuron circuitry in the brain that excites a cortical g spot?

Yes!

Intelligence is definitely an essential quality.

Glad FT and carrerinyes get it (hopefully frequently)!
While I'm at it, Elf Fury, I am still thinking about your question regarding metaphors and dreams, my circuits all atingle.

There ain't no cure for circuits all atingle

Sure it is. Dumb is fun but it gets boring real fast!
