Important note: National average IQ scores are estimates based on limited sample sizes and vary across studies. These figures are heavily influenced by socioeconomic factors, access to quality education, healthcare, nutrition, and testing conditions. They do not reflect the intelligence or potential of any individual from that country. IQ scores measure specific cognitive skills and should be interpreted within their proper scientific context.

Understanding IQ Distribution
It's crucial to remember that national averages represent the middle of a wide distribution. Within every country, individual IQ scores span the full range from below 70 to above 130 and beyond. A country with an average IQ of 100 will have many individuals scoring well above and below that number. Factors like socioeconomic status, nutrition, education quality, and access to healthcare play significant roles in cognitive development and test performance.
The Flynn Effect — the observation that IQ scores have risen substantially over time in many countries — suggests that environmental improvements like better nutrition, healthcare, and education access can significantly impact cognitive test performance at the population level. Many developing nations are experiencing rapid improvements in these areas.
