American IQ scores have rapidly dropped, proving the 'Reverse Flynn effect'

I read somewhere a couple of years ago, some scientists showed that as CO2 levels rise, IQ scores drop.

But, me, I fully believe it is due to the war on public education by the US GOP. I wish these articles broke down these scores by school type the children go/went to.

Kids sent to high end private schools by their ultra rich parents probably have seen no such decline. It is like the US is trying to move into a caste society, ruling class and serf class.

edit: spelling

There's not even close to enough CO2 in the atmosphere to have that profound of an effect on our IQ. If it was then our own breath would give us all brain damage and our species would have gone extinct millions of years ago. Pollution and poor air circulation indoors is one thing, but the ambient CO2 in the atmosphere outdoors is another.
