I was surprised to see this country ranked #9. I always thought we were on the first 4.
The intelligence scores came from work carried out earlier this decade by Richard Lynn, a British psychologist, and Tatu Vanhanen, a Finnish political scientist, who analysed IQ studies from 113 countries, and from subsequent work by Jelte Wicherts, a Dutch psychologist.
Countries are ranked highest to lowest national IQ score.
