I think we should start by saying what we think the true definition of intelligence is.
According to me intelligence is the ability to use your cumulative knowledge in the moment that it is most appropriate in order to obtain certain objective. If lots of people have the same knowledge but only 1 reaches the objective, then he is smarter than the others.
I say this because most IQ examinations, ask for things that require previous knowledge that you may not know, or that have been never taught to you in school nor college. And because of that you don't know the answer, but that does not mean at all you are stupid.
