One theory of this phenomenon added the "existential" and "naturalistic" components of it in the second edition of Frames of Mind. The componential, experimental, and practical types of it appear in Sternberg's "triarchic" theory, which resists the unified "g-factor" measure of it. Howard Gardner supports the theory that this thing is "multiple".  Measures of this have steadily increased in accordance with the Flynn effect. The Stanford-Binet metric assesses this phenomenon, which is often measured as 100 times a ratio between a person's real age and mental age. For 10 points, name this generalized concept of human mental ability, measured by a namesake "quotient."
