​10 Countries with lowest IQ in the world

IQ provides insights into socio-economic, cultural and environmental factors that influence cognitive development. IQ is the ratio of an individual's cognitive ability to their age group. It is usually measured using standardized tests designed to assess various cognitive competencies such as problem-solving, reasoning, memory, and comprehension. Scores are then normalized to create a distribution with a mean of 100. Countries with the least average IQs usually end up facing major socio-economic challenges. These include not having access to quality education and healthcare, as well as decent nutrition, political instability, or even conflict. Here are 10 countries with the lowest IQ in the world according to the World Population Review 2024.

Countries with lower IQ averages, as noted by the World Population Review 2024, often experience challenges like poverty, limited healthcare, and restricted educational opportunities. These factors contribute to ongoing socio-economic struggles, creating a cycle that can be hard to break.

Countries with lower average IQ scores often face considerable socio-economic challenges. Key factors like limited access to quality education, healthcare, and adequate nutrition can significantly affect cognitive development. Additionally, political instability, economic hardship, and even conflict contribute to reduced opportunities and resources, impacting the overall cognitive potential within populations.

A country’s economic growth can be affected by having a lower average IQ among its population. Societies with lower cognitive levels may struggle in areas that require technical skills and problem-solving, which can reduce productivity and limit innovation. When a national average IQ is low, it often links to slower economic progress, as people may not have the necessary cognitive skills for complex jobs or starting new businesses. Investing in education, healthcare, and nutrition can help improve cognitive development, which in turn supports stronger economic growth and stability.

Nepal has the lowest average IQ of 42.99, largely due to poverty, lack of proper nutrition, and under-resourced schools. Political instability and natural disasters have further disrupted education and infrastructure.

Liberia's average IQ of 45.07 is impacted by decades of civil war and political instability. These factors have severely disrupted the education system and access to quality healthcare.

Sierra Leone also has an average IQ of 45.07, affected by civil war, Ebola, and poverty. These challenges lead to limited access to education and healthcare.

Guatemala's average IQ of 47.72 is hindered by poverty, malnutrition, and lack of educational resources. Rural areas, in particular, suffer from underfunded schools.

The Gambia has an average IQ of 52.98, influenced by poverty, malnutrition, and an underfunded education system. Cultural views sometimes deprioritize formal schooling.

Nicaragua's average IQ of 52.69 is affected by poverty and unemployment. Many children work instead of attending poorly resourced schools, especially in rural areas.

Guinea has an average IQ of 53.48 due to poverty, malnutrition, and an underdeveloped education system. Cultural factors also affect access to formal schooling.

Ghana's average IQ of 58.16 is influenced by poverty and disparities between urban and rural education systems. Despite improvements, many schools still lack resources.

Ivory Coast has an average IQ of 58.16, with widespread poverty, malnutrition, and underfunded schools. Rural areas are particularly affected.

South Sudan's average IQ of 58.16 stems from ongoing conflict, poverty, and lack of access to education and healthcare. These factors severely impact cognitive development

Mauritania has an average IQ(Lynn/Becker) of 59.76. Mauritania, one of the largest yet least populated nations in West Africa, holds vast reserves of resources such as fish, iron, oil, and gold. However, over 16.6% of its population still lives below the extreme poverty line.

Mali has an average IQ of 59.76(Lynn/Becker). Mali is the 8th largest country in Africa and is completely landlocked. Approximately 60 percent of people live in rural areas and most Malians work in agriculture.
