In his book From Strength to Strength, Arthur Brooks cited research by Raymond Cattell, a British Psychologist, who identified two types of intelligence in his book entitled Abilities: Their Structure, Growth, and Action. The first is fluid intelligence, which Cattell defined as the ability to reason, think flexibly, and solve novel problems. It is what we commonly think of as raw smarts, and researchers find that it is associated with both reading and mathematical ability. Cattell, who specialized in intelligence testing, observed that it was highest relatively early in adulthood and diminished rapidly starting in one’s thirties and forties.
