Nice book summary from Gladwell suggesting that IQ is not innate: “I.Q. measures not just the quality of a person’s mind but the quality of the world that person lives in”. Given that IQ scores are rising over time (requiring ever harder tests) and that many comparators turn out to be mistaken (e.g. Asian over American), you can’t really support the use of IQ for very much at all, other than mental gymnastics.
