A new study in Acta Psychologica reveals that schooling largely explains IQ differences in identical twins raised apart. When their educations are very dissimilar, their IQ scores can be as different as those between complete strangers.
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.
Being reproducible does not mean the test is correct. I can reproducible do wrong math too.
And does that mean we should be skeptical of math tests too?
