IQ, or Intelligence Quotient, is a measure that tries to assess human intelligence through various cognitive tasks.

Here are the top 10 countries with the lowest average IQ scores.

What is IQ?

IQ, or Intelligence Quotient, is a way to measure how smart someone is. It checks how well a person can solve problems, think, and remember things. Most people score between 85 and 115, with 100 being the average. It is often used in schools and by doctors to understand a person’s thinking skills.

How is IQ Measured?

IQ, or Intelligence Quotient, is assessed by evaluating an individual’s cognitive abilities. The main goal is to determine how a person’s mental development compares to what is expected at their age.

An IQ score below 70 is often considered a sign of intellectual disability, while an IQ above 130 places someone in the category of being highly gifted.
