Keep the low IQ migrants out and the IQ stays up.
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.
Hopefully this study was done with integrity and didn't hide 'inconvenient' facts.
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.
This makes sense, as well as the fact that we all carry computers around us in our pocket. Problems or questions that we used to figure out on our own, are now solved with a quick search.
Looks like people aren't born intelligent and schools are lowering standards.
Carrying computers doesn't make people less intelligent, just having less knowledge remembered. Actual problem solving skills are still needed.
Maybe in some cases.
I'd say it takes problem solving to read and map and plot a course for instance. How many people even own paper road maps anymore?
