Formally, the law purports to be based solely in reasoned analysis, devoid of ideological bias or unconscious influences. Judges claim to act as umpires applying the rules, not making them. As most legal scholars understand, however, the impression that the legal system projects is largely an illusion. Over the last decade or so, political scientists and legal academics have begun studying the linkages between ideologies, on one hand, and legal principles and policy outcomes on the other. This book is the first to bring many of the world's experts on those topics together to examine the sometimes unsettling interactions between psychology, ideology, and law.
