Introduction

The average IQ is generally considered to be reflective of the overall well-being of a country, as the average IQ of a population is closely related to a variety of factors such as education, health, income inequality, and government financing of education can all have a significant impact on IQ levels within a population.

Research has shown that individuals who have access to quality education, adequate healthcare, and financial resources tend to perform better on IQ tests. In contrast, those who lack these resources may be at a disadvantage, and their IQ scores may not be an accurate reflection of their true intelligence. This is the reason why rankings such as these are often considered to put higher income countries at an unfair advantage compared to lower income countries, as they measure and compare countries’ citizens on aspects that can widely vary from country to country, so these scores should be taken as an indication, not an exact measure.

Based on the data from the Ulster Institute, there is a significant variation in average IQs among countries. The countries with the highest average IQs are Japan, Taiwan, Singapore, Hong Kong, and the People’s Republic of China, all with average IQs above 104. On the other hand, countries such as Mozambique, Burkina Faso, Niger, Antigua and Barbuda, and Rwanda have the lowest average IQs, all below 71.

Many factors can explain the differences in average IQ among countries, as the average IQ is influenced by various factors such as genetics, environment, education, and cultural background, among others. For instance, countries with a strong emphasis on education, such as Japan and Singapore, tend to have higher average IQs. Similarly, countries with a history of political and social instability, poverty, and lack of access to education and healthcare, such as many African countries, tend to have lower average IQs. Therefore, it is essential to consider various factors that influence IQ when comparing average IQs among countries.

The country with the highest IQ in the world is Japan, with an average IQ of 106.48. The second country with the highest IQ is Singapore, with an average IQ of 106.47. Taiwan is the third country with the highest IQ, with an average IQ of 105.89. Hong Kong has the fourth highest IQ, with an average IQ score of 105.37. China and South Korea are the fifth and sixth countries with the highest IQs, with an average IQ of 104.1 and 102.35 respectively. Belarus, the seventh on the top 10 countries with the highest IQ, has an average IQ of 101.6. Finland ranks eighth country with the highest IQ, with an average IQ score of 101.2. Then come Liechtenstein and Germany as the ninth and tenth countries with the highest IQs, with an average IQ of 101.07 for Liechtenstein, and 100.74 for Germany.

The ten countries with the highest IQ are :

1. Japan – 106.48
2. Taiwan – 106.47
3. Singapore – 105.89
4. Hong Kong – 105.37
5. China – 104.1
6. South Korea – 102.35
7. Belarus – 101.6
8. Finland – 101.2
9. Liechtenstein – 101.07
10. Germany – 100.74

Highest IQ in the World

Japan has the highest IQ in the world, with an average IQ of 106.48. This score is due to a variety of factors, most notably the highly educated population and their incredible work ethic. Japan’s educational system emphasizes critical thinking, problem-solving abilities, and creative thinking skills—all essential for developing high intelligence. Japanese culture values hard work and discipline from a very early age, which encourages its citizens to strive for excellence in all areas of life. Furthermore, cognitive training games such as sudoku are incredibly popular in Japan and help the brain stay active and healthy while helping people process information faster. The combination of these factors results in individuals with higher levels of intelligence who have a greater capacity for learning than individuals with lower levels of intelligence. This explains why Japan has been able to consistently achieve its average IQ score over time.

Countries with Lowest IQ

The ten countries with the lowest IQ in the world are Nepal, Liberia, Sierra Leone, Guatemala, Gambia, Nicaragua, Guinea, Ghana, Ivory Coast, and South Sudan. Nepal ranks first in the list of countries with the lowest IQ, with an average IQ of 42.99. The second country with the lowest IQ is Liberia, with an average IQ of 45.07. Sierra Leone ranks third country with the lowest IQ, with an average IQ of 45.07. With average IQ scores of 47.72 and 52.68, Guatemala and Gambia are the fourth and fifth countries with the lowest IQ. Nicaragua, the sixth country with the lowest IQ, has an average intelligence quotient of 52.69. Guinea ranks seventh country with the lowest IQ, with an average score of 53.48, followed by Ghana, ranking eighth lowest IQ in the world, with an average IQ score of 58.16. Finally, the ninth and tenth countries with the lowest IQ are Ivory Coast and South Sudan, with average IQ scores of 58.16 and 58.61 respectively.

The countries with the lowest average IQs have a number of factors in common that contribute to an overall low IQ score. Many of these nations have recently experienced significant population growth, leaving governments struggling to allocate limited resources to an ever-enlarging population. Another reason for the low average IQ score is overall development levels, as nations within the top ten countries with the lowest IQs are also among those which are ranked as some of the most underdeveloped nations in the world. Finally, another reason often mentioned to explain the low average IQs in certain countries is political instability, as this affects the development of solid educational systems that greatly helps improve IQ levels.

The ten countries with the lowest IQ are :

1. Nepal – 42.99
2. Liberia – 45.07
3. Sierra Leone – 45.07
4. Guatemala – 47.72
5. The Gambia – 52.98
6. Nicaragua – 52.69
7. Guinea – 53.48
8. Ghana – 58.16
9. Ivory Coast – 58.16
10. South Sudan – 58.61

Lowest IQ Country

Nepal is considered to be the lowest IQ country in the world with an average score of 42.99. However, it should be noted that this figure was measured on a small sample of people, which is only partially representative of Nepal population’s average IQ, and thus most probably shows results far below what they actually are. There are, however, other factors that could help make sense of Nepal’s low IQ score. Nepal is a landlocked country located between India and China, which has long been isolated from many parts of the world and hence lacks access to modern facilities or educational resources. Additionally, poverty has been rampant in Nepal for many years, leaving little resources to build a strong educational system or even basic health care services. As a result, there is an overall less developed state among the population when it comes to intellectual capabilities such as problem-solving, logical reasoning, and understanding concepts that require deeper analytical thinking. Moreover, with limited access to higher education institutions both in Nepal and abroad, few people are able to gain knowledge or hone their analytical skills which further contributes to a low average IQ when compared to other countries worldwide. Ultimately, this leaves Nepal as having one of the lowest average IQs compared to all other nations across the globe.

Average IQ by Age

IQ scores can vary depending on age, with different age groups showing different average IQ levels. For children, the average IQ score is generally considered to be around 100. However, as people age, their IQ tends to increase, with the average IQ for adults being higher than that of children. The peak age for IQ is usually around the age of 25, where the average IQ score is approximately 110. From that point on, IQ scores tend to decline gradually with age, with the average score dropping by around 1-2 points every decade.

Source

The IQ ranking that we use on this page is the Lynn and Becker study, Intelligence of Nations, which attempts to rank countries based on their average IQ scores. To gather its data, they used standardized IQ tests administered across various countries and compiled by various sources. The main conclusion of the study is that there are significant differences in average IQ scores among different nations, with the United States scoring an average IQ of almost 98. The authors note that these differences in IQ scores may be attributed to various factors, such as genetics, education, and socio-economic factors.

The Lynn and Becker Intelligence of Nations study comes with its limitations, however, and has been criticized for its methodology and potential biases, but many researchers argue that the study still provides valuable insights into the relationship between intelligence and a variety of social, economic, and cultural factors. And while the study might not always accurately reflect the average IQ of a given country, the study has been useful for researchers to identify patterns and trends in cognitive ability across different populations and countries, has helped inform policy decisions related to education, healthcare, and other areas, and is still used in many studies today.

Afghanistan has an average IQ of 82.12 and ranks as ninety-eighth in the world for average IQ. This is a result of factors such as poverty, malnutrition, and limited access to educational opportunities. Many parts of Afghanistan lack basic infrastructure and resources, including educational materials and qualified teachers. This contributes to lower academic performance among many Afghan children, leading to lower overall IQ scores compared to other nations. Research also suggests that armed conflict and political instability contribute to educational underperformance and limited access to educational resources which can adversely affect cognitive development and IQ scores over time.

Brazil has an average IQ of 83.38 and ranks ninety-third in the world for average IQ. The majority of people in Brazil come from an educational background that is traditionally focused on vocational rather than theoretical skills. This means that the Brazilian education system often does not provide enough opportunities for students to develop higher-order thinking skills, which can lead to lower overall IQ scores among the population. Additionally, socio-economic factors such as poverty, malnutrition, and lack of access to healthcare can also play a role in lowering the average IQ score among Brazilians.

The Dominican Republic has an average IQ of 82.05 and ranks one-hundredth in the world for average IQ. This lower IQ score can be attributed to a number of factors including a lack of educational resources and disparities in income levels. The country's history of poverty and inequality also contributes to this lower IQ. It’s worth noting that when it comes to cognitive scores, only 8 percent of young people in the Dominican Republic have an IQ above 100 – the global average score. As such, the average IQ score for children in the Dominican Republic is well below those found in other parts of Latin America and most developed countries.

Mali’s education system is one of the weakest in West Africa and only 58% of children between the ages 6-11 attend school. There are also very few resources available for those wishing to pursue higher education, contributing to a low adult literacy rate of 28%, significantly lower than the world average. All these factors contribute to Mali’s lower-than-average IQ score, making it more difficult for citizens to develop complex problem-solving skills and analytical reasoning that may otherwise be attributed to a higher IQ score.

Niger has an average IQ of 70.82 and ranks one-hundred-fifty-one in the world for average IQ. It's worth noting that most low-IQ countries have high rates of poverty, and Niger is no exception - with over half of its population living below the poverty line. Education levels are also generally quite low, often due to limited access or resources. In many cases, public schools are overcrowded or lack trained teachers capable of delivering quality instruction. This further contributes to Niger's lower-than-average IQ score and creates a significant challenge for their educational system moving forward.
