"National IQ" refers to the average intelligence quotient (IQ) score of a country's population. It is often derived from various studies and assessments that measure cognitive abilities, such as problem-solving and reasoning skills. These scores can provide insights into educational systems, economic development, and social factors within a nation. Factors influencing national IQ can include access to education, healthcare, nutrition, and socio-economic conditions. Researchers often analyze data from standardized tests to estimate these averages, which can vary significantly between different countries and regions. Understanding national IQ can help policymakers address educational and developmental challenges.
