I'll just copy and paste what I said on another post about this:
IQ is genetic. We're importing low IQ retards from third world shitholes, hence the collective IQ drops. Pretty simple. The headline is basically pro-immigration of retards.
some part of IQ is genetic, another part can be trained if started at young age
Which is why the US educational system is the way it is, that is not promoting IQ growth in the students
as a result, many Americans think IQ is entirely genetic, when in fact it's the public educational system is so shit (by choice or accident, take your pick), that its actively detrimental to the intelligence growth of all of their students.
Studies on black children adopted at birth and raised by white families have shown that IQ tracks pretty closely with white children during primary education, then begins to deviate during middle school, eventually reaching about a halfway point between adopted white children (to control for the impact of adoption itself on IQ) and black children raised by their own parents. Thus, it seems to be about half and half.
Sorry, but I'm not committed enough to this to go find the link.
Picture checks out.

If it's not ENTIRELY genetic, it has to be like 90% of the formula, imo.
genetics does play a part in the IQ formula, but we can't say for sure how large that part is
this is the best offer I can give you
