Why is it that IQ doesn’t correlate perfectly (or even correlate strongly, for that matter) with success in life? This is the question Sternberg explores in Successful Intelligence. Sternberg is a professor at Yale and is one of the world’s leading authorities on intelligence as well as wisdom and love (and the most-quoted psychologist alive or dead). He defines successful intelligence as “the kind of intelligence used to achieve important goals”—the kind of intelligence that is actually helpful in predicting future success. (The only kind we’re really interested in, right?) The individuals who demonstrate this successful intelligence have something in common: “They know their strengths; they know their weaknesses. They capitalize on their strengths; they compensate for or correct their weaknesses. That’s it.” Sounds pretty simple, eh? Sternberg walks you through his scientific exploration and validation of his conclusion and offers specific steps to develop your successful intelligence “quotient.”
