I think this would be a good variable to analyze. A lot of third-world countries didn't have a large automobile infrastructure, and so they had lower lead levels, leading to smarter people with less crime.
This could be the source of "smart Asian" stereotype.
But, I don't know if atmospheric lead pollution is uniform globally or localized.
- Nasrudith 8y agoIt is very localized - areas by old highways have issues with higher lead concentration in soil. Which seems intuitive but CFCs are heavier than air yet can still wind up high enough to cause ozone layer issues via air currents
