Intelligent Soldiers More Likely To Die In Combat
Analysis of IQ statistics shows that Scottish soldiers who survived the second world war were less intelligent on average than those who died fighting the Nazis.
The data is available because Scotland conducted national IQ tests for all 11-year-olds in 1932; no other country has ever done such a massive, thorough test of the mental ability of its population.
Apparently, Scottish soldiers who died in WWII and had taken the IQ tests as children had achieved an average IQ score of 100.8, while survivors who had taken the same test averaged 97.4.
The higher war death rate for smart individuals finally explains studies which found a dip in intelligence among Scottish men directly after the war.
