Written by a psychologist with expertise in psychology and the law, the book Not Fair! The Typology of Commonsense Unfairness is worth exploring even if you have wondered only fleetingly about the concept of unfairness. Academics in traditional social science disciplines such as psychology, anthropology, philosophy, theology, criminology, and political science constitute the principal audience for the book. Secondary audiences include lawyers, divorce and labor mediators, psychologists and other mental health clinicians, politicians, and public-spirited citizens.
