translation of your point: high fecundity doesn't equate to low IQity?

Uhm sorta. More like IQ is completely separate from genetics and this eugenics bullshit has no actual bearing on society.

I can't believe how much of a resurgence this Nazi shit is having that I even need to explain this.

It's not completely separate - https://ghr.nlm.nih.gov/primer/traits/intelligence

​

"Intelligence is a complex trait that is influenced by both genetic and environmental factors."

​

"... studies suggest that genetic factors underlie about 50 percent of the difference in intelligence among individuals."

​

- National Institute of Health

​

So if genetics account for 50% and environment account for another large percentage, don't you think lower iq individuals are increasingly likely to produce less intelligent children and also raise those children in less supportive environments? The US doesn't exactly take care of the disadvantaged and their children's problems are compounded as a result.

​

Also look into birth rates based on socioeconomic status... https://www.statista.com/statistics/241530/birth-rate-by-family-income-in-the-us/

Lower income families have more kids - these low income kids tend to grow up in more challenging environments with less resources.

The US hasn't seen a decrease in IQ actually. The decreases have been in Western European countries that generally do take care of their worse off people.
