Also, those most outraged are currently importing massive amounts of third worlders into developed countries.
Mean IQ of a population decreases when millions of lower-IQ people enter that population.

> One potential explanation was quasi-eugenic. As in the movie “Idiocracy,” it was suggested that average intelligence is being pulled down because lower-IQ families are having more children ("dysgenic fertility" is the technical term). Alternatively, widening immigration might be bringing less-intelligent newcomers to societies with otherwise higher IQs.
> However, a 2018 study of Norway has punctured these theories by showing that IQs are dropping not just across societies but within families. In other words, the issue is not that educated Norwegians are increasingly outnumbered by lower-IQ immigrants or the children of less-educated citizens. Even children born to high-IQ parents are slipping down the IQ ladder.
> Some environmental factor — or collection of factors — is causing a drop in the IQ scores of parents and their own children, and older kids and their younger siblings. One leading explanation is that the rise of lower-skill service jobs has made work less intellectually demanding, leaving IQs to atrophy as people flex their brains less.
