“Average joe”. Humanity evolves slowly over long periods. The average joe today is far more educated than one from 200 years ago.

Far more educated. But certainly not smarter.

And it's not at all clear if that education does anything other than magnify their intellectual predispositions. The smart people can make great strides, but the stupid will be stupid louder and harder. And the average may well just be... more average.

IQ levels has risen on average because of nutrients, not using lead and education.

An increase in blood lead from 10 to 20 micrograms/dl was associated with a decrease of 2.6 IQ

Risen by a few points. Statistically significant but not really meaningful.

…and to still believe that IQ levels measure something meaningful is pretty average Joe anyway. Could be the rise of videogames for all we know.

IQ score rises (Flynn effect) are most likely spurious and do not reflect any increase in actual on-the-spot problem-solving ability.

IQ scores were never intended to be used to compare across cohorts. To do so is invalid.
