The comparative assessment considered aspects such as logic, memory, and analytical skills, ensuring a uniform metric for all analyzed countries.
Online IQ tests, like those used to create global rankings, have limited scientific validity due to the lack of rigorous psychometric standards, uncontrolled test environments, and biased demographic samples. Unlike professional evaluations, which measure various aspects of intelligence under expert supervision, these tests simplify the assessed skills and may be influenced by distractions or commercial motivations.
Thus, while they generate curiosity and entertainment, they should not be considered a reliable or precise measure of intelligence.
