These Are the Countries With the Highest IQs

4. South Korea average IQ - 104.6

Although the education system in South Korea is different than that of most other countries, they've still seen a sharp increase in IQ over time. Today, students may be required to attend school from Mondays to Saturdays for nine months out of the year - with some classes extending on into the evening.

The country also has one of the highest percentages when it comes to people who have completed tertiary-level degrees and literacy rates exceeding 99%. This high level of skill among its citizens can be attributed largely to their intense focus on education.
