Prevailing economic theory presumes that agents act rationally when they make decisions, striving to maximize the efficient use of their resources. Psychology has repeatedly challenged the rational choice paradigm with persuasive evidence that people do not always make the optimal choice. Yet the paradigm has proven so successful a predictor that its use continues to flourish, fueled by debate across the social sciences over why it works so well. Intended to introduce novices to rational choice theory, this accessible, interdisciplinary book collects writings by leading researchers. The Limits of Rationality illuminates the rational choice paradigm of social and political behavior itself, identifies its limitations, clarifies the nature of current controversies, and offers suggestions for improving current models. In the first section of the book, contributors consider the theoretical foundations of rational choice. Models of rational choice play an important role in providing a standard of human action and the bases for constitutional design, but do they also succeed as explanatory models of behavior? Do empirical failures of these explanatory models constitute a telling condemnation of rational choice theory or do they open new avenues of investigation and theorizing? Emphasizing analyses of norms and institutions, the second and third sections of the book investigate areas in which rational choice theory might be extended in order to provide better models. The contributors evaluate the adequacy of analyses based on neoclassical economics, the potential contributions of game theory and cognitive science, and the consequences for the basic framework when unequal bargaining power and hierarchy are introduced.

In Minimal Rationality, Christopher Cherniak boldly challenges the myth of Man the the Rational Animal and the central role that the "perfectly rational agent" has had in philosophy, psychology, and other cognitive sciences, as well as in economics. His book presents a more realistic theory based on the limits to rationality which can play a similar generative role in the human sciences, and it seeks to determine the minimal rationality an actual agent must possess.

In Between Magic and Reality, Vibeke Steffen, Steffen Jöhncke, and Kirsten Marie Raahauge bring together a diverse range of ethnographies that examine and explore the forms of reflection, action, and interaction that govern the ways different contemporary societies create and challenge the limits of reason. The essays here visit an impressive array of settings, including international scientific laboratories, British spiritualist meetings, Chinese villages, Danish rehabilitation centers, and Uzbeki homes, where they encounter a diverse assortment of people whose beliefs and concerns exhibit an unusual but central contemporary dichotomy: scientific reason versus spiritual/paranormal belief. Exploring the paradoxical way these modes of thought push against reason's boundaries, they offer a deep look at the complex ways they coexist, contest one another, and are ultimately intertwined. Vibeke Steffen is associate professor in the Department of Anthropology at the University of Copenhagen, where Steffen Jöncke is senior advisor. Kirsten Marie Raahauge is associate professor in the School of Design at the Royal Danish Academy of Fine Arts in Copenhagen.

The word ‘rationality’ and its cognates, like ‘reason’, have multiple contexts and connotations. Rational calculation can be contrasted with rational interpretation. There is the rationality of proof and of persuasion, of tradition and of the criticism of tradition. Rationalism (and rationalists) can be reasonable or unreasonable. Reason is sometimes distinguished from revelation, superstition, convention, prejudice, emotion, and chance, but all of these also involve reasoning. In politics, three views of rationality – economic, moral, and historical – have been especially important, often defining approaches to politics and political theory such as utilitarianism and rational choice theory. These approaches privilege positive or natural law, responsibilities, or human rights, and emphasize the importance of culture and tradition, and therefore meaning and context. This book explores the understanding of rationality in politics and the relations between different approaches to rationality. Among the topics considered are the limits of rationality, the role of imagination and emotion in politics, the meaning of political realism, the nature of political judgment, and the relationship between theory and practice. This book was originally published as a special issue of Global Discourse.

Normal Rationality is a selection of the most important work of Edna Ullmann-Margalit, presenting some influential and widely admired essays alongside some that are not well known. She was an unorthodox and deeply original philosopher whose work illuminated the largest mysteries of human life. Much of her writing focuses on two fundamental questions. (1) How do people proceed when they cannot act on the basis of reasons, or project likely consequences? (2) How is social order possible? Ullmann-Margalit's answers, emphasizing what might be called biased rationality, are important not only for philosophy, but also for political science, psychology, sociology, cognitive science, economics (including behavioral economics), law, and even public policy. Ullmann-Margalit demonstrates that people have identifiable strategies for making difficult decisions, whether the question is small (what to buy at a supermarket) or big (whether to transform one's life in some large-scale way). She also shows that social dilemmas are solved by norms; that invisible-hand explanations take two identifiable (and dramatically different) forms; that trust can emerge in seemingly unpromising situations; and that considerateness is the foundation on which our relationships are organized in both the thin context of the public space and the intimate context of the family. One of the distinguishing features of Ullmann-Margalit's work is its close attention to the details of human experience, and its use of those details to offer fresh understandings of social phenomena. Her essays cast new light on a diverse assortment of problems in philosophy, social science, and individual lives.
