IQ is a relative measure, pretending to be the % of the normal level of a individual in a similar age, in resumen: Relative to what or whom?. Intelligence isn't medible directly, because it isn't a objective value, depending on the test, it isn't only the capability to solve problems, it's also the capability to interact with others, emphatic capability, kinetic capabilities. Eg. Newton maybe was a genios with an IQ of 190 in Science and Math, but in interactions with others stupid like a brick (Asperger syndrom)
