>Arthur R. Jensen - The g Factor: The Science of Mental Ability (1998)
>Jensen fully and clearly explains the psychometric, statistical, genetic, and physiological basis of g, as well as the major theoretical challenges to the concept. For decades a key construct in differential psychology, the g factor's significance for scholars and researchers in the brain sciences as well as education, sociology, anthropology, evolutionary psychology, economics, and public policy is clearly evident in this, the most comprehensive treatment of g ever published.
