I think this is getting close to the idea of liquid intelligence and crystallized intelligence. The scary thing about valuing the liquid kind is that it’s the one that shrinks with age. Crystallized intelligence grows with age.

Working memory size, processing speed, fluid intelligence (novel problem solving / creativity), and crystallized intelligence (knowledge), are are all different components of intelligence that are pairwise not perfectly correlated.

Some person A can solve problem X in 1 minute and problem Y in 1 hour, while some person B can solve both in 10 minutes, even with the same crystalized intelligence.
