That’s not the point. Math is well defined and can be checked outside of tests if it is wrong or false. We can’t do that with IQ tests. But that is a separate issue. We have no way of knowing if the IQ tests are sufficient, because it includes more than “math”. And are not well defined either.
Edit: The point is, something being reproducable does not mean its correct.
And does that mean we should be skeptical of math tests too?
