This book explores the assumptions and preconceptions underlying common statements and theories of intelligence and examines how these arise out of different social contexts in which different ideas about intelligence wax and wane. It contrasts popular and informal conceptions of intelligence with the demands of rigorous scientific theory and tackles intelligence as an area of psychological theory, research and practical application.

The text considers the historical origins of the term intelligence , IQ testing, information processing, developmental and social cognition models of intelligence and the nature versus nurture debate. This critical review of intelligence aims to help students develop a detached stance on the subject and so escape reliance on the kind of cliches that engender constant controversy.
