Honestly, I feel like math is one thing I don't have to practice or drill as it's possible to deduce most things without actually having to drill/learn the concepts - at least on the basic level and if given enough time. This is why I loved math as a kid, because I was too lazy to study and it was one subject I could do well at by nature. So I think the article downplays the genetic influence of it. But of course it's better to think that you can have more effect on your intelligence rather than not psychologically, because otherwise you may end up doing nothing to improve yourself. But I still feel that genetics has very high influence on innate math, abstract logic capabilities. Some people are just addicted to solving abstract problems while others can't force themselves to think about these at all. For instance, if there's an abstract problem I could spend hours and hours without noticing time passing by, and I don't think I ever had any specific raising or environmental influences to be this addicted. There's other issues that I have absolutely zero patience to do, it's as if I have ADHD in some fields and I'm only deeply interested in certain fields. And to me it makes evolutionary sense. It's better in a community to have people specialised to different niches, so people's brains are wired differently to support different niches and specialisations. You can't have everyone thinking about abstract problems all the time - because there would be no one to do the real worldly things any more and abstract thinkers would simply die of hunger or eaten by predators.
