dbo:abstract | - A large body of research indicates that intelligence measures such as intelligence quotient (IQ) varies between individuals and between certain groups, and that they correlate with socially important outcomes such as educational achievement, employment, crime, poverty and socioeconomic status. In the United States, certain public policies and laws regarding employment, military service, education and crime incorporate IQ or similar measurements. Internationally, certain public policies, such as improving nutrition and prohibiting neurotoxic toxins, have as one of their goals raising or preventing a decline in intelligence. (en)
