Humans love to classify and compare. Most of us compete to demonstrate we are better and the intelligence is not different. Having a way to measure this human parameter precisely is a normal consequence. Plus, from a more useful perspective, we need to have some way of measure a parameter if we want to study it. If we were trying to compare the results of two different strategies to improve the intelligence, we would need a precise method to measure the intelligence of every individual.
