Something interesting is that in a study people could actually differentiate between intelligent people and average based on their behavior, I don't remember in which test were based on, I think the iq is just a part of an individual that doesn't describe the success or others parts of the person as a whole, anyway I have an IQ of 113, slightly better than average, but it depends of the culture, education and income , it might explain why on average Latin American and black people score whorse that white people in U.S., it depends of country, but is just specialization on certain task, adaptability is something important to measure in a given culture
