Questionable IQ Data and Its Origins
There is significant concern regarding the reliability of the IQ data used to create global maps of intelligence. Much of the data for various countries, especially those in Africa, stems from flawed methodologies, where estimates were derived from small, unrepresentative samples rather than comprehensive testing. For instance, estimates for Equatorial Guinea were based on children from a developmentally disabled home in Spain, and the figure for Somalia was influenced by a single sample of refugees in Kenya. These questionable sources highlight that the low IQ scores reported do not accurately reflect the cognitive abilities of populations but instead indicate broader issues like malnutrition and lack of access to education.
