Country with Highest IQ: The intelligence quotient, or IQ, is a measure of intelligence. An IQ test is designed to measure a person's cognitive abilities, including problem-solving skills, abstract thinking, and general knowledge. It is a daunting task to find the country with the highest IQ. This is difficult because various factors are involved in conducting such a comparative study. Most of the IQ rankings are not comprehensive because of various factors, notably the number of participants taking the test.
This article is based on data from participants taking the standardised AVSEO IQ test, a non-verbal test based on Raven's Progressive Matrices that assesses cognitive abilities, particularly abstract reasoning and problem-solving.
How many countries took the test?
A total of 188 countries participated in this year's test, and based on the test, Singapore emerged as the most intelligent country, with an average IQ of 106.61, followed by China in second position with 105.61, and South Korea with 105.26. The complete list is shared in the section below.

China, one of the largest economies in the world, is also placed second in the list of smartest countries in the world with a score of 105.61. That is a reflection of the education system of the country.
3. South Korea
As mentioned in the report, most East Asian countries are among the most intelligent countries in the world, and South Korea is an example of that.
The reason South Koreans are intelligent is that there is a high emphasis on scoring good marks and grades, to the extent that candidates are considered for a job if they have great overall scores.
Numbers play a big role in determining your level of intelligence in South Korea.
No wonder, with such pressure to perform, the population needs to evolve and enhance their skills. South Korea is the third most intelligent country in the world, scoring an average IQ of 105.26.
4. North Korea
Making it to the fourth position in the study is North Korea with an average IQ of 104.40, this is partly due to sharing the same genetic heritage as its neighbour South Korea, therefore emphasis is on academic and ideological training.
5. Japan
As per the report, the Japanese scored 103.63, which makes them the fifth best on the list. Studies have found that Japanese people are good at problem-solving, but the results cannot be generalised.
Japan is famous in the world for the quality of its electronics, cars and motorcycles, which are built using technology that is more advanced than others.
Although Taiwan and Hong Kong scored 104.78 and 104.54, respectively, they are not included in the country list, as Hong Kong is a special administrative region of China. In contrast, Taiwan is not internationally recognised as a country despite meeting all criteria for statehood.
Conclusion
This was all about the countries with the highest IQ. In the end, we can conclude that there isn't a single official IQ test which is accepted worldwide; various IQ tests use various methodologies to study intelligence ( Standford Binet Intelligence Scale, Raven's Progressive Matrices, or WAIS). This article is based on the IQ international test, or AVSEO IQ test, which is based on Raven's Progressive Matrices.
