25 Countries With The Highest Average IQ

Have you ever wondered which country has the highest average IQ? Many people have been asking this question and many studies have been conducted to try and answer it. One of the most recent and comprehensive IQ studies was conducted in 2016 by the Statistic Brain Research Institute. You won’t believe what they found. Curious to know if your country is among the smartest in the world? Check out the 25 countries with the highest average IQ.

Note: Rankings of the average IQ by countries are always controversial and should be interpreted with caution. Some rankings are shared by multiple countries with the same IQ score. They are separated according to the alphabetical order within that ranking. The following list is NOT a ranking of average IQ by race.
