Countries list by their Average IQ: Which are the smartest countries in the world?

Intelligence quotient, or IQ as we often refer to it, provides a measure of human cognitive abilities in relation to one’s age group. While IQ is by no means a comprehensive assessment of one’s mental prowess or potential, it does offer an intriguing glimpse into intellectual capabilities at a national level. To gauge countries’ intelligence, experts often utilize average national IQ scores. It’s important to note, these scores aren’t static but are subject to a variety of influences ranging from education systems, socio-economic factors, and even nutritional considerations.

From the rich trove of public data detailing average national IQs, we embark on an enlightening journey across the globe, exploring regions that lead the charts and those that fare relatively low.
