Hive Mind by Garett Jones

How Your Nation's IQ Matters So Much More Than Your Own

An argument that a society’s average cognitive ability — even small differences — has outsized effects on economic productivity, governance, technology adoption, and social cooperation. Drawing on cross‑country data, historical examples, and economic reasoning, the author claims higher average intelligence produces multiplier effects by improving learning, rule‑following, coordination, innovation, and institutional performance. The book discusses policy implications for education, immigration, and institutional design, while addressing measurement issues and common critiques of linking cognition to macroeconomic outcomes.
