> "Intelligence isn't very hard to measure. The methods to test it are quite mature." Intelligence is a measure of aptitude, but aptitude applies to a broad range of activity, and not all aptitude is numerically quantifiable (in any meaningful sense, at least). For example, two broad categories of intelligence are academic intelligence and emotional intelligence. Excellence in one field does not necessarily transfer to all fields, otherwise socially gifted people would always make the best academic students, and from personal observation I can see this doesn't tie up with reality.
