Introduction

Intelligence is a fascinating aspect of human diversity, and researchers often measure it using an Intelligence Quotient (IQ). While IQ is just one way to gauge cognitive abilities, it provides insight into how different populations compare in terms of problem-solving, critical thinking, and memory. In this article, we’ll delve into the average IQ scores around the world and highlight some of the countries with the highest and lowest scores. Average IQ in the World: The global average IQ is set at 100, with most people falling within a range of 85 to 115. This standard allows for a comparison of intelligence levels across different nations. It’s essential to note that IQ tests may not capture the full spectrum of human intelligence, and factors like culture and education can influence the results.

Countries with the Highest IQ:

United States – 74.88
United Kingdom – 64.19
Germany – 64.18
Australia – 63.96
Singapore – 63.60
Sweden – 61.58
Switzerland – 61.57
Canada – 61.15
Finland – 60.45
Denmark – 60.25

These scores suggest that individuals in these countries tend to perform well on standardized intelligence tests, reflecting their cognitive abilities.

Countries with Lowest IQ:

Mauritania – 11.55
Mozambique – 10.93
Malawi – 10.74
Chad – 10.32
Ethiopia – 10.30
Mali – 9.91
Rwanda – 9.89
Madagascar – 8.99
Burundi – 8.79
Guinea – 6.76

Our article draws heavily from the study “The Intelligence of Nations” by Richard Lynn and David Becker, which provides a comprehensive dataset of national IQs. The study uses a rigorous methodology to estimate and calculate national IQs, ensuring transparency and accuracy. Some highlights from the study include Japan having the highest average IQ in the world, and the observation that factors such as education, healthcare, and socio-economic conditions can significantly influence a country’s average IQ.

who has the lowest iq in the world?

People who have a condition called anencephaly, has the lowest iq in the world.

Some babies are born with a condition called anencephaly, where their brains are not fully formed. Unfortunately, some animals that are aware and can feel emotions end up being used for human food after facing a lot of suffering.

When we talk about ‘IQ,’ it’s not a perfect measure of intelligence. Traditional IQ tests mainly focus on one aspect of intelligence related to autism and don’t consider social skills or problem-solving abilities that are crucial for human intelligence. Intelligence involves understanding the world around us, not just logical and linguistic thinking.

Even though anencephalic babies have severe cognitive challenges, they still have experiences and can feel pleasure and pain.
