You've got a massive and unsupported gap in logic there. Correlation does not equal causation.
Plenty of other things happened in that time span. Lead gasoline, for example, became massively more common and has a direct impact on IQ. Similarly, our education system has been crumbling as boomers took control.
But don't let things like skepticism get in the way of your racism. That would be inconvenient.
Results for subgroups make it pretty obvious. Did only migrants huff gasoline? Well, actually, if they were abbos, but that makes up enough Americans to fill a high school gymnasium. Koreans and Japanese breath air from the same atmosphere, they went up 7.7 points per decade while the west went up about 3, from 1970 to 1990, then the west started to stagnate. Americans grow up today with the benefit of rigorous FDA, EPA, OSHA, CPSC and NHTSA regulations. They limit exposures to anything with too many letters in the name. Our forefathers played with toys painted with lead, breathed in those asbestos fibers and sprayed themselves with agent orange even outside the war. Leaded gasoline was phased out in the 70s and 80s and catalytic converters introduced, all around the same time the US started to stagnate, the dead fucking opposite of what the pollution theory would predict.
Its funny to me how IQ testing is done by evaluating the conscious pattern recognition of peoples, but the results of IQ testing are always challenged by people who consciously reject the easily recognizable patterns.
