IQ is compute speed, not storage. It has nothing to do with knowledge. IBM used to give one out as part of their hiring process, years ago, and even I took it the entire test was a timed multiple choice exam where every question was looking at an object made out of cubes and choosing the correct orientation of the object from the choices, after the object was arbitrarily rotated according to instructions in the question.
Then, IQ can be derived by determining how quickly all participants can answer the questionnaire correctly, and ranking their speeds, and then normalizing the values so 100 is in the middle.
Turns out, scores will fall along a bell curve if you do that. You can call that phenomenon whatever, but most people call it IQ and hopefully I've explained well why that has nothing at all to do with static knowledge in this comment.
