I think a chronic problem is people and studies starting with a false premise without even realizing it. "Affluence is strongly correlated with higher IQ, therefore IQ is a socioeconomic problem" You have the classic example of the smart person saying "I grew up in a house with a lot of books" And then everyone reflexively takes away "Having lots of books around when you are young leads to more success!" But virtually no one goes to "Smart people tend to have lots of books in their home, and they also tend to give birth to smart children, who are unsurprisingly drawn to reading books" You see this everywhere.
