Which Country Has the Highest IQ in 2026? Full Top 10 List Revealed
Global IQ rankings often spark curiosity as they attempt to compare average cognitive abilities across different countries. The latest 2026 data shows that while the top positions remain largely unchanged, a few nations have either improved their scores or slipped slightly compared to last year.
These rankings are based on standardised testing and participant samples. Experts often highlight that such figures are influenced by multiple factors, including education systems, cultural environments, and socio-economic conditions. So while the list offers useful insights, it should be seen as a broad indicator rather than a final measure of intelligence.
Here is a detailed look at the top 10 countries with the highest average IQ in 2026.
1. South Korea
South Korea tops the list with an average IQ of 106.97. The improvement from last year is small but steady.

A large number of participants in the study adds credibility to the data, showing consistent performance over time.
2. China
China secures the second position with an IQ of 106.48. Although there is a slight decline from last year’s figure, the country continues to rank among the highest globally. With one of the largest participant samples in the dataset, the results are considered statistically strong and reliable.

Japan stands third with an IQ score of 106.30. The change from the previous year is minimal, indicating stability rather than fluctuation. Japan’s consistent performance reflects its strong educational framework and emphasis on learning.
4. Iran
Iran ranks fourth with an IQ of 104.80. This year shows a noticeable drop compared to the previous data. While the reason is not clearly defined, it could be linked to variations in sample size or testing conditions. Despite the decline, Iran remains among the top-performing nations.
