I am under the impression that intelligence doesn't have universal standards, and an iq test only really tells you how much you know based on one culture's rating system. I assign iq tests and ratings extremely little value.

Regardless of whether this is true, IQ should be consistent across a culture like Norway, right? Particularly when the results don't show a consistent effect across families.
