The Bell Curve: Intelligence and Class Structure in American Life

This book describes the state of scientific knowledge about questions that have been on people's minds for years but have been considered too sensitive to talk about openly--among them, IQ's relationship to crime, unemployment, welfare, child neglect, poverty, and illegitimacy; ethnic differences in intelligence; trends in fertility among women of different levels of intelligence; and what policy can do - and cannot do - to compensate for differences in intelligence.
