What researchers at the University of Bern, Switzerland, call 'crystallized intelligence', is really specialized, encoded brilliance. [Yes, the hermit is aware that the term, along with the term 'fluid intelligence', have been around for much longer than this current research.]
Why?
The learned, honed versifier may be wholly inadequate in novel situations in the three dimensional world, but he is not inadequate in novel situations in the realms of poesy. He crafts complex brilliance to be sung for centuries. Maybe not G, maybe not IQ, but far greater.
The hermit's subjectively derived impression is that the development of scholarship comes at the expense of I.Q., but that it is well worth the trade, lest he falls asleep and wakes up in Waterworld, or anywhere where raw thinking skills are more in demand than artistic specialization.
There is a certain slow pace that sets in once scholarship is pursued. It is as if the pulsations of the brain are gently coaxed into a softer sine wave, and that new knowledge is acquired as the being snakes by the wave nadir, and dreadfully bold advances are made as the radar blip meanders through the peak.
