The extremely young science of the microbiome is going from microbiome/disease 'associations' to establishing causation. Weird how this hasn't occurred for IQ in the past 100 years...https://twitter.com/EricTopol/status/938475406507720704 …

IQ tests are pretty good at determining whether one person is smarter than another.
Because of how items are selected for the test. It's based on prior assumption.
Do IQ tests generally tell you who's smarter or not?
Because of how they're made. You can make tests that show other groups as smarter based on item selection. This is a fact.
And if you object to the concept of "smarter" or of intelligence generally, I think you should know better
They are 'smarter' due to how the tests are constructed. Does anyone know how IQ tests are constructed and why that calls into question the assumptions and conclusions drawn from it?
This is incohereht
No it's not. Test creators keep 50 percent of items people get right and the smaller proportion of items people get right and wrong. This forces the curve and shows the presuppositions. You can make other groups more 'intelligent' with the right item selection. Do you deny that?
The idea that you can make other groups score higher with different item selection is basically false.
It definitely is not false. How are IQ tests created?
I don't care
So it doesn't matter how IQ tests are created? Item selection doesn't matter?
