Intelligence is Inherited

In practice, IQs measure only one skill: how well you do on IQ tests.
(Incidentally, this isn't sour grapes -- I don't know what my IQ is exactly, but I'm told it's within a fraction of the top 1 percentile. And I don't consider myself particularly intelligent either.)
There is no good quantifiable measurement for intelligence.
You mean there is no generally accepted definition of intelligence.
Once you reach a conclusion as to what skills represent intelligence, it is quite clear that a test evaluating those skills is a very short step.
