Twin studies can't prove something is caused by "genetics"[0]; twins are not free of environmental factors and don't necessarily have the same genome. Genetics, like many scientific fields that can't do real experiments, is just people abusing statistics for fun.

[0] if it did, this wouldn't mean anything, because it can't be used to make predictions, because you don't know if any random person X you are trying to predict trait Y of has these "genetics".

I don't really have a horse in this race but you're basically denying the ability of science to have anything to say outside of the hard sciences, which I disagree strongly with.

"Can't be used to make predictions"... seriously? These factors can be used to make predictions. Now whether these things are just correlates with other more fundamental factors, or causal - I thought that was where the conflict was.

No, economics can make useful predictions because they understand proper study design. Most other fields can't though.
