You sure it's not because of cold weather and slowed metabolism?
- sgt 8y agoSo countries with hotter climates have higher IQ's?
- Symmetry 8y agoA plausible mechanism would be that cold weather causes people to spend time indoors with the windows closed, leading to more CO2 buildup, leading to IQ declines. Indoor CO2 buildups of, say, 1000 ppm aren't uncommon and lead to a clear decline in cognitive functions. This wouldn't be a problem in hot countries.
