IQ is a weak measure of anything remotely important. For one reason IQ tests are typically convergent in that they typically test a central way of doing things against a single most correct answer that often excludes creativity. A divergent test, however, examines creativity by looking for the quantity and diversity of answers to questions by a participant. Secondly, IQ is mostly not an earned quality. Intelligence is generally an inherited quality, but it can be modified by practicing a specific skill that is directly tested for in IQ tests. The ability to improve IQ by practicing a skill is a measure of behavior rather than intelligence. A far more important quality is the behavior by which skills are learned. Qualities like persistence, determination, focus, criticality, objectivity, and so forth do more to influence perceptions of intelligence than there mere speed of learning, which is what intelligence actually is. That said measurements of speed of learning or raw information processing are weak indicators of potential to excel where those qualities are important.
