"All modern nations-even Norway, even Japan-contradict themselves: they contain multitudes. How are such contradictions to be dealt with, such multitudes managed? This series of vivid and circumstantial case studies of everything from group rights in India and religious conflicts in France to customary marriages in South Africa and cultural defenses in American courts reveals the depth of the problems posed to democratic governments by cultural difference, how they are being approached, and what the results have been. A searching discussion of an urgent issue."
-CLIFFORD GEERTZ, INSTITUTE FOR ADVANCED STUDY

"A lively, deeply insightful discussion of the profound ethical dilemmas posed by the unexpected collision of two of liberalism's favored assumptions."
-JEROME KAGAN, PROFESSOR OF PSYCHOLOGY, HARVARD UNIVERSITY

"Engaging Cultural Differences provides a fresh analysis on aspects of the challenges facing liberal pluralistic societies as they attempt to accommodate the cultural values and preferences of their new citizens. It includes penetrating perspectives that call for a reevaluation of the dominant theories on the subject. A must read for scholars and policy makers reflecting on the impact of emigration on Western societies and the dynamics of integration and assimilation in the age of globalization."
-YVONNE YABECK HADDAD, PROFESSOR OF HISTORY OF ISLAM AND CHRISTIAN-MUSLIM RELATIONS, GEORGETOWN UNIVERSITY

"The question of cultural difference has long been a double- pronged thorn in the side of liberalism. It has dented confident assertions of universal individual rights with allegations of discrimination. And it has punctured claims of broadly based tolerance with accusations of indifference to oppression. This remarkably powerful volume, rich in both empirical detail and theoretical sophistication, confronts these issues head on from a range of different perspectives-legal, psychological, anthropological, historical. It will change the way many people think and become indispensable reading for scholars interested in liberalism, practitioners working within multicultural institutions, and activists involved in human rights."
-JACQUELINE BHABHA, EXECUTIVE DIRECTOR, UNIVERSITY COMMITTEE ON HUMAN RIGHTS STUDIES, HARVARD UNIVERSITY

"When a society professes commitment to equal liberties, and also to tolerance of cultural difference, the resulting paradoxes are not merely intellectual. In Engaging Cultural Differences, some two dozen distinguished scholars in law and the social sciences consider the law's confrontations with deep cultural difference in six liberal nations. Some subjects are broad (international human rights, cultural models of identity and equality), and some particular (individual claims to asylum, or to the 'cultural defense' in criminal law). Both general readers and specialists in many disciplines have much to learn from these essays-even readers who find some cultural differences more engaging than others."
-KENNETH L. KARST, DAVID G. PRICE AND DALLAS P. PRICE PROFESSOR OF LAW EMERITUS, UNIVERSITY OF CALIFORNIA, LOS ANGELES

Liberal democracies are based on principles of inclusion and tolerance. But how does the principle of tolerance work in practice in countries such as Germany, France, India, South Africa, and the United States, where an increasingly wide range of cultural groups holds often contradictory beliefs about appropriate social and family life practices? As these democracies expand to include peoples of vastly different cultural backgrounds, the limits of tolerance are being tested as never before. Engaging Cultural Differences explores how liberal democracies respond socially and legally to differences in the cultural and religious practices of their minority groups.

Building on such examples, the contributors examine the role of tolerance in practical encounters between state officials and immigrants, and between members of longstanding majority groups and increasing numbers of minority groups. The volume also considers the theoretical implications of expanding the realm of tolerance. Some contributors are reluctant to broaden the scope of tolerance, while others insist that the notion of "tolerance" is itself potentially confining and demeaning and that modern nations should aspire to celebrate cultural differences.

Coming to terms with ethnic diversity and cultural differences has become a major public policy concern in contemporary liberal democracies, as they struggle to adjust to burgeoning immigrant populations. Engaging Cultural Differences provides a compelling examination of the challenges of multiculturalism and reveals a deep understanding of the challenges democracies face as they seek to accommodate their citizens' diverse beliefs and practices.

Classical economic theory assumes that people in risk situations follow a course of action based on a rational, consistent assessment of likely outcomes. But as Zur Shapira demonstrates in Risk Taking, corporate managers consistently stray from the prescribed path into far more subjective territory. Risk Taking offers a critical assessment of the relationship between theory and action in managerial decision making.

Shapira offers a definitive account of the classical conception of risky decision making, which derives behavioral prescriptions from a calculation of both the value and the likelihood of possible outcomes. He then demonstrates how theories in this vein have been historically at odds with empirical observations. Risk Taking reports the results of an extensive survey of seven hundred managers that probed their attitudes and beliefs about risk and examined how they had actually made decisions in the face of uncertainty. The picture that emerges is of a dynamic, flexible process in which each manager’s personal expertise and perceptions play profound roles.

Managerial strategies are continually modified to suit changing circumstances. Rather than formulating probability estimates, executives create potential scenarios based not only on the possible outcomes but also on the many arbitrary factors inherent in their own situations. As Shapira notes, risk taking propensities vary among managers, and the need to maintain control and avoid particularly dangerous results exercises a powerful influence. Shapira also examines the impact of organizational structure, long-term management objectives, and incentives on decision making.

With perceptive observations of the cognitive, emotional, and organizational dimensions of corporate decision making, Risk Taking propels the study of managerial risk behavior into new directions. This volume signals the way toward improving managerial decision making by revealing the need for more inclusive choice models that augment classical theory with vital behavioral observations.

"In Selman's new work, Jean Piaget meets John Dewey. Thirty years of creative theorizing and research in developmental psychology is forged in the crucible of clinical practice and educational reform."
-J. LAWRENCE ABER, director, National Center for Children in Poverty, Mailman School of Public Health of Columbia University

"In this wise and humane book, Robert Selman integrates the insights that he has gained during his thirty-year career as a distinguished clinical and developmental psychologist. Both the breadth and depth of Selman's vision are remarkable. He offers the reader valuable methods for promoting growth in teachers as well as children; and, just as importantly, he puts practical methods in the context of a systematic theoretical framework, drawn from the best psychological traditions, that enables the reader to think systematically about what children and their teachers need, and why. The book is charter for a truly developmental approach to addressing the social-emotional needs of today's young. Educators, researchers, and all those concerned with the future of our children will find The Promotion of Social Awareness enormously helpful."
-WILLIAM DAMON, professor of education and director, Center on Adolescence, Stanford University

"In The Promotion of Social Awareness, Robert Selman describes the history of his innovative and wide-ranging efforts to promote children's social competence. His multifaceted approach blends and respects both research and practice, showing how each benefits from the other. Beginning with developmental theory and clinical practice, Selman's vision expanded to encompass the use of children's literature to promote social competence, the investigation of teachers' beliefs and practices, and the creation of informative assessments. With his collaborators, he shows in rich detail how research and practice must navigate the broader social and political landscape and confront questions of value and culture. What a model for the committed psychologist!"
-HERBERT GINSBURG, Jacob H. Schiff Foundation Professor of Psychology and Education, Teachers College, Columbia University

"For those who see great promise in developmental psychology for education, and more generally seek to strengthen practice through judicious application of theory, this is a stimulating and valuable book. Educators will surely benefit from making use of it."
-DR. DAVID A. HAMBURG, president emeritus, Carnegie Corporation of New York and visiting scholar, Department of Psychiatry, Cornell University Weill Medical College

Education specialists have written volumes on the best ways to help children learn to read and write, but who is helping them navigate the potentially treacherous waters of social interactions? While in school to study, children are also preoccupied with understanding the rules governing social relationships. Issues of trust and loyalty, rivalry and conflict, belonging and exclusion affect all school-aged children, but very few lesson plans include social development skills.

The Promotion of Social Awareness summarizes thirty years of research on the social development of children in elementary and middle school, and shows how this work has led to a series of programs that promote the social competence of children and adolescents. Rich with lessons drawn from real life, the book includes an in-depth account of the author's partnership with an innovative program designed to help educators promote a sound ethic of social relationships among children, a case study of a teacher particularly gifted at promoting such relationships, and the tale of how the author's theoretical framework fared cross-culturally when exported to Iceland.

The Promotion of Social Awareness documents Robert Selman's efforts both as a practitioner trying to help young people develop their interpersonal skills and as a researcher attempting to understand the factors that promote or hinder social development. Selman believes that getting along with others involves concrete and measurable social skills and actions that can be taught. The book underlines how the science of social development has given rise to initiatives and programs that can be used in educational settings to help children get along with each other, and may in the long run help prevent violence, drug abuse, and prejudice.

Unique in its marriage of theory and practice, The Promotion of Social Awareness will appeal to a wide readership, including developmental psychologists, educators, and parents.

Leon Festinger's forty-year scrutiny of that "curious animal, the modern human being" fundamentally transformed psychological thinking and shaped an entire scientific field, that of social psychology. The twenty-four papers brought together for the first time in Extending Psychological Frontiers encompass the classic contributions and critical turning points of Festinger's long career.

Spanning the post-war decades, this unprecedented volume reveals the full scope, diversity, and import of Festinger's work. Its thematic arrangement clarifies the complex network of problems that preoccupied Festinger and the unique imaginative style that characterized his intellect. Whether examining the voting behavior of Catholics and Jews, the meaning of minute eye movements, the decisions of maze-running rats, or the proselytizing behavior of cultists, Festinger consistently transcended the traditional bounds of the discipline. His theory of cognitive dissonance, which describes how people attempt to resolve the tensions that result when they hold simultaneously two inconsistent beliefs, challenged preexisting psychological theories and produced more important ideas and experimentation than any other development in social psychology. Major writings on group dynamics, decision making, and perceptual processes further underscore the impact of Festinger's research not only on psychology, but also on a wide range of intellectual fronts, from literary theory to ethnology and from historical studies to contemporary political analysis.

Extending Psychological Frontiers is an invaluable resource, providing a comprehensive and coherent picture of an extraordinary body of work.

To what extent can and should people participate in dealing with the personal problems they bring to consulting professionals? This book presents two alternative models for the conduct of such professional-client relationships as those between lawyers and clients and doctors and patients. One model, called the traditional, prescribes a role of minimal participation for the client. The other, called the participatory, prescribes a role of decision-making shared by the client and the professional. After presenting the two models and their implications, the book systematically tests their validity in a case study of the lawyer-client relationship in the making of personal injury claims.

The distinctive feature of this work is a sophisticated and objective test of the traditional proposition that passive clients get better results than active clients. Evidence drawn from a sample of actual cases of personal injury claimants reveals that active clients in fact fare significantly better than passive clients.

The book is important and novel in four respects: it offers the first clear and realistic proposal for increasing the control people can have over the complex problems they bring to professionals; it presents concrete evidence that lay participation in complex decision making need not be inefficient; it gives practical advice to clients and to lawyers for dealing with each other more effectively and it presents a comprehensive picture of the actual and often dramatic experiences of accident victims, and what it is like to make a personal injury claim.

Social Diagnosis is the classic in social work literature. In it Miss Richmond first established a technique of social casework. She discusses the nature and uses of social evidence, its tests and their practical application, and summarizes the lessons to be learned from history, science, and the law. While other aids in diagnosis have been added to the caseworker's equipment, the assembling of social evidence is still an important discipline of the profession, to which this volume continues to make a significant contribution. No revision of the book has ever been made nor does any later book take its place.

"A stimulating, provocative collection of some of the best minds studying racism, culture, and identity, this intelligent volume does not flinch at the tough issues in multicultural relations. Novice readers will walk away informed; experts will come away intrigued; everyone will be enriched, thinking a lot harder about the role of social science in confronting these crucial challenges to our country and our world."
- SUSAN T. FISKE, University of Massachusetts

"Prentice and Miller have assembled a stellar cast of leading researchers in the areas of culture, identity, and intergroup relations to tackle perhaps the most pressing social psychological problem facing us as we start the new millennium-the problem of cultural identity and its relationship to intergroup conflict and social harmony. The refreshing juxtaposition of research on social identity, intergroup conflict, stigma, diversity, culture, ethnicity, race, and gender provides a salutary framework for new theoretical advances in this area."
- MICHAEL A. HOGG, University of Queensland

"A timely, interesting, and important book with contributions from some of the most eminent scholars studying the psychology of culture, ethnicity, and racism. It asks and answers fundamental questions about the consequences of multiculturalism in America- especially those consequences relevant to ethnic conflict. Each chapter is provocative and illuminating. Taken together, these chapters reveal many subtle differences between peoples that have very unsubtle consequences when these peoples come into contact. As a whole, the book offers a forceful argument that the psychological implications of multiculturalism are not only fascinating, but they really, really matter."
- MARK SCHALLER, University of British Columbia

"Now, more than ever, it is essential to probe the cultural foundations of intergroup conflict-both in the United States and internationally. This important book presents the latest psychological research on the cultural diversity debate by renowned scholars in the field. They provide much-needed insights into current intergroup conflict while suggesting some optimism for the future."
- VICTORIA ESSES, University of Western Ontario

Thirty years of progress on civil rights and a new era of immigration to the United States have together created an unprecedented level of diversity in American schools, workplaces, and neighborhoods. But increased contact among individuals from different racial and ethnic groups has not put an end to misunderstanding and conflict. On the contrary, entrenched cultural differences raise vexing questions about the limits of American pluralism. Can a population of increasingly mixed origins learn to live and work together despite differing cultural backgrounds? Or, is social polarization by race and ethnicity inevitable? These are the dilemmas explored in Cultural Divides, a compendium of the latest research into the origins and nature of group conflict, undertaken by a distinguished group of social psychologists who have joined forces to examine the effects of culture on social life.

Cultural Divides shows how new lines of investigation into intergroup conflict shape current thinking on such questions as: Why are people so strongly prone to attribute personal differences to group membership rather than to individual nature? Why are negative beliefs about other groups so resistent to change, even with increased contact? Is it possible to struggle toward equal status for all people and still maintain separate ethnic identities for culturally distinct groups? Cultural Divides offers new theories about how social identity comes to be rooted in groups: Some essays describe the value of group membership for enhancing individual self-esteem, while others focus on the belief in social hierarchies, or the perception that people of different skin colors and ethnic origins fall into immutably different categories. Among the phenomena explored are the varying degrees of commitment and identification felt by many black students toward their educational institutions, the reasons why social stigma affects the self-worth of some minority groups more than others, and the peculiar psychology of hate crime perpetrators. The way cultural boundaries can impair our ability to resolve disputes is a recurrent theme in the volume. An essay on American cultures of European, Asian, African, and Mexican origin examines core differences in how each traditionally views conflict and its proper methods of resolution. Another takes a hard look at the multiculturalist agenda and asks whether it can realistically succeed. Other contributors describe the effectiveness of social experiments aimed at increasing positive attitudes, cooperation, and conflict management skills in mixed group settings.

Cultural Divides illuminates the beliefs and attitudes that people hold about themselves in relation to others, and how these social thought processes shape the formation of group identity and intergroup antagonism. In so doing, Cultural Divides points the way toward a new science of cultural contact and confronts issues of social change that increasingly affect all Americans.

Presents a collection of papers by economists theorizing on the roles of altruism and morality versus self-interest in the shaping of human behavior and institutions. Specifically, the authors examine why some persons behave in an altruistic way without any apparent reward, thus defying the economist's model of utility maximization. The chapters are accompanied by commentaries from representatives of other disciplines, including law and philosophy.

"Imprisoning America breaks new ground in our understanding of the impact of mass incarceration on society. By combining theoretical perspectives with data-driven analysis, the volume makes a significant contribution to our understanding of the complex dynamics that have been set in motion by the uniquely American 'experiment' with the use of incarceration."
-MARC MAUER, assistant director, The Sentencing Project

"The penal system now governs the lives and life chances of millions of Americans-not just the young minority men who are its chief targets but also their neighbors, their families, and, above all, their children. Imprisoning America is a major step forward in the effort to trace the deep social and economic impacts of penal policy. Using solidly documented data, careful social science, and dispassionate analysis, the contributors reveal the startling extent of the 'collateral damage' in America's decades-long war against crime. This book's message is an urgent one that citizens and policy-makers need to hear."
-DAVID GARLAND, Arthur T. Vanderbilt Professor of Law and professor of sociology, New York University

"Blending perspectives and insights in unique and comprehensive ways, this volume systematically reveals the unrecognized toll of collateral as well as direct damage mass incarceration has imposed on our nation's social fabric during a quarter century binge of ill-planned penality. This collection of original articles launches a much needed and long overdue research literature with extraordinarily important policy implications for the past, present, and future use of imprisonment in this country."
-JOHN HAGAN, John D. MacArthur Professor of Sociology and Law, Northwestern University

Over the last thirty years, the U.S. penal population increased from around 300,000 to more than two million, with more than half a million prisoners returning to their home communities each year. What are the social costs to the communities from which this vast incarcerated population comes? And what happens to these communities when former prisoners return as free men and women in need of social and economic support? In Imprisoning America, an interdisciplinary group of leading researchers in economics, criminal justice, psychology, sociology, and social work goes beyond a narrow focus on crime to examine the connections between incarceration and family formation, labor markets, political participation, and community well-being.

The book opens with a consideration of the impact of incarceration on families. Using a national survey of young parents, Bruce Western and colleagues show the enduring corrosive effects of incarceration on marriage and cohabitation, even after a prison sentence has been served. Kathryn Edin, Timothy Nelson, and Rechelle Parnal use in-depth life histories of low-income men in Philadelphia and Charleston, to study how incarceration not only damages but sometimes strengthens relations between fathers and their children. Imprisoning America then turns to how mass incarceration affects local communities and society at large. Christopher Uggen and Jeff Manza use survey data and interviews with thirty former felons to explore the political ramifications of disenfranchising inmates and former felons. Harry Holzer, Stephen Raphael, and Michael Stoll examine how poor labor market opportunities for former prisoners are shaped by employers’ (sometimes unreliable) background checks. Jeremy Travis concludes that corrections policy must extend beyond incarceration to help former prisoners reconnect with their families, communities, and the labor market. He recommends greater collaboration between prison officials and officials in child and family welfare services, educational and job training programs, and mental and public health agencies.

Imprisoning America vividly illustrates that the experience of incarceration itself—and not just the criminal involvement of inmates—negatively affects diverse aspects of social membership. By contributing to the social exclusion of an already marginalized population, mass incarceration may actually increase crime rates, and threaten the public safety it was designed to secure. A rigorous portrayal of the pitfalls of getting tough on crime, Imprisoning America highlights the pressing need for new policies to support ex-prisoners and the families and communities to which they return.

"Nothing is more basic to the human condition than the capacity for commitment, and nothing is more important to the capacity than its biological underpinnings and evolution. Randolph Nesse, serving as editor and connecting essayist, and the other authors of Evolution and the Capacity for Commitment are among the leaders in and around this newly emerging field of scholarship."
-EDWARD O. WILSON, Harvard University

"If the genes of the self-serving are more likely to be perpetuated in succeeding generations, how is it that so many of us forgo self-interest in order to honor commitments, devote large portions of our lives to the quest for knowledge, defending animal rights, human rights, or remaining true to a cause past reason? We humans routinely behave better than conventional evolutionary theory predicts we should. Evolution and the Capacity for Commitment resolves this paradox and in doing so, extends sociobiological theory to more fully encompass idiosyncracies of the human heart. This is a revelatory book that carries us beyond premature conclusions about innate selfishness that, if accepted, erode human relationships based on any other premise. Anyone looking for a rigorous alternative to Darwin's 'universal acid,' should read this book."
SARAH BLAFFER HRDY, University of California at Davis

"In the 1970s, the word 'selfish' was kidnapped from common language to be applied to genes. This metaphor, however, did not say much about human psychology. Exploring the emotional make up of our species while firmly staying within an evolutionary framework, this volume spells out better than any before what is wrong with a narrow focus on human selfishness."
-FRANS B. M. DE WAAL, Emory University

"This is a very valuable contribution to our understanding of commitment which no serious student of the subject will wish to miss."
-ROBERT TRIVERS, Rutgers University

Commitment is at the core of social life. The social fabric is woven from promises and threats that are not always immediately advantageous to the parties involved. Many commitments, such as signing a contract, are fairly straightforward deals, in which both parties agree to give up certain options. Other commitments, such as the promise of life-long love or a threat of murder, are based on more intangible factors such as human emotions. In Evolution and the Capacity for Commitment, distinguished researchers from the fields of economics, psychology, ethology, anthropology, philosophy, medicine, and law offer a rich variety of perspectives on the nature of commitment and question whether the capacity for making, assessing, and keeping commitments has been shaped by natural selection.

Game theorists have shown that players who use commitment strategies—by learning to convey subjective offers and to gauge commitments others are willing to make—achieve greater success than those who rationally calculate every move for immediate reward. Evolution and the Capacity for Commitment includes contributions from some of the pioneering students of commitment. Their elegant analyses highlight the critical role of reputation-building, and show the importance of investigating how people can believe that others would carry out promises or threats that go against their own self-interest. Other contributors provide real-world examples of commitment across cultures and suggest the evolutionary origins of the capacity for commitment.

Perhaps nowhere is the importance of commitment and reputation more evident than in the institutions of law, medicine, and religion. Essays by professionals in each field explore why many practitioners remain largely ethical in spite of manifest opportunities for client exploitation. Finally, Evolution and the Capacity for Commitment turns to leading animal behavior experts to explore whether non-humans also use commitment strategies, most notably through the transmission of threats or signs of non-aggression. Such examples illustrate how such tendencies in humans may have evolved.

Viewed as an adaptive evolutionary strategy, commitment offers enormous potential for explaining complex and irrational emotional behaviors within a biological framework. Evolution and the Capacity for Commitment presents compelling evidence for this view, and offers a potential bridge across the current rift between biology and the social sciences.
