A person’s IQ (intelligence quotient) is a score derived from standardized tests designed to measure human intelligence and intellectual potential. IQ tests include questions that measure reasoning and problem-solving skills. The discovery that average IQs differ worldwide has been a focus of inquiry and controversy.
Also, the difference between the countries with the highest average IQ and the US was 10 points, which is the same kind of increase you can get in IQ testing scores if you tell the tester that they’ll get $10 if they do well.
