National infectious disease burden strongly predicts average national IQ

A note I wrote by hand before this schema existed. This paragraph must survive materialize appending its marker blocks rather than clobbering this file.

Evidence

The scientists found that the greater the burden of infectious disease, the lower a nation’s average IQ.36 — Harriet A. Washington, A Terrible Thing to Waste, 937
