Intelligence Quotient or IQ is often used as an indicator of the intelligence of an individual or population. Despite some limitations, IQ test results are often used to assess the cognitive abilities and education of a country.
The average human IQ ranges from 85 to 115. However, this number can vary between countries and geographic regions. Many factors cause a person’s IQ to be well below average, ranging from genetic factors, environmental factors, lack of access to education, to social and economic factors.
According to World of Data Info, Richard Lynn and David Backer researched the IQ of a country’s population, resulting in 128 countries ranked from highest to lowest IQ.
Based on this research, Nepal occupies the first position among the 10 countries with the lowest IQ in the world, according to World of Data Info. This country, famous for its stunning mountain views, has a low average IQ population due to several factors, including limited access to education and poverty.
Meanwhile, East Asian countries dominate the top 10 list of nations with the highest average IQ.
