10 Countries With Lowest IQ In The World: Nepal Tops The List...India Also Present In The Lineup?

IQ (Intelligence Quotient) offers valuable insights into the socio-economic, cultural, and environmental conditions that shape cognitive development. Defined as the ratio of an individual's cognitive ability to the average within their age group, IQ is typically measured through standardized assessments. These tests evaluate a range of mental abilities, including problem-solving, memory, reasoning, and comprehension. The resulting scores are normalized, with the average set at 100.
