Intelligence and public policy

A large body of research indicates that IQ ("intelligence quotient") and similar measures vary 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.
