How can societies experience such dramatic reversals [as the end of apartheid in South Africa, widespread smoking bans and Republican control of Congress] in such short periods? In his inventive and sometimes astonishing book, Timur Kuran offers an answer--one that bears not just on revolutionary movements, but also on feminism, conformity, cognitive dissonance, the moral majority, 'outing' homosexuals, rationality, hate speech codes, Gorbachev, hippies and the caste system (all of which make prominent appearances in these pages)...Much of the interest of Kuran's book is owed to his insistence, unusual and refreshing among economists (of whom he is one), that people's choices, and even their desires, are not given and fixed, but are a function of social and psychological conditions, above all pressures imposed by other people...Kuran's book is a terrific success.

A splendid book. It tackles a long list of interesting and important questions that have been discussed at length, and largely unsuccessfully, by scholars from each of the social sciences. The narrow rational choice model simply cannot answer many of these questions. Psychological theories by themselves cannot even address many of them. And sociological theories that take the group as the unit of analysis have made little progress. Kuran patiently and intelligently blends the insights of these disciplines into a behavioral model that moves the discussion forward on many fronts.

From the caste system of India, to communism's rise and fall, to the continuing controversy over affirmative action, Timur Kuran's new theory of social evolution is as provocative as it is ambitious. Merging insights from many disciplines, Private Truths, Public Lies seeks to show how 'preference falsification' shapes social action, biases knowledge, inhibits change, and (from time to time) unleashes revolution...An excellent book that can be read by scholars of all disciplines. Its interdisciplinary insights illuminate a raft of social, political, and economic phenomena.

Economist Timur Kuran has written a fascinating study of how even formally 'free' citizens can be socially pressured into 'living a lie,' publicly justifying beliefs and practices that they privately reject, even abhor.

The core idea of this stimulating book is simple to grasp: Social factors, the nature of which is variable with the circumstances, can have the effect that people falsify their private preferences when they have to express them publicly.

[Kuran's] arguments are elegantly made and the lengthy discussions of the applications of the basic ideas are well researched and suffiently detailed to be of considerable interest in their own right...This is a thoughtful, imaginative, and stimulating book which deserves a wide audience.

Timur Kuran takes us on a grand journey through world history, from the creation of the Indian caste system to present-day racial quotas in the United States. The journey is guided by the search for the social consequences of a phenomenon that Kuran argues is all-pervasive: preference falsification...Kuran's book opens important new perspectives for the analysis of both individual choice and social change.

Few recent contributions to the literature of social science open so many windows. This engagingly written book carries its learning and sophistication lightly.

A fascinating study in social and political psychology and public opinion...For those who stress that war, violence and peace start in the minds of men, this is certainly an important work.

A compelling theoretical analysis of how contextual structures of power influence an individual to conform to public sentiment. Combining perspectives of economics, psychology, and sociology, the author provides countless insights into the process whereby individuals repress their true opinions because of possible censure or admonition from those representing the prevailing sentiment...Kuran's argument has crucial implications for social theory...Highly recommended for its thorough and insightful analysis.

[E]normously subtle...[Kuran's] exposition of 'preference falsification' is the most original work of social science I have read for many a long year. The term and concept have innumerable applications and deserve to enter the language...The conclusion Kuran reaches is a powerful one which is at odds with most social science and indeed everyday thought about our ability to understand or forecast social change...The text is entirely lucid and the theme is of the utmost importance.

Kuran argues that agents choose 'public preferences' which are contrary to their 'private preferences' in order to attain 'reputational utility.' Such 'preference falsification' pushes, in turn, ideas away from private consciousness, originating 'knowledge falsification' (i.e., indoctrination). Kuran's book is well-argued, never dull, and studded with diverse anecdotes. It is destined to become a classic, providing a methodological individualistic alternative to Karl Marx's theory of ideology...Academics as well as educated persons will come back after reading the book more enriched on how to understand our complex world.

Kuran is the leading pioneer in examining the harsh and the subtle ways in which we are induced to deceive our public, our acquaintances, and eventyally ourselves about the issues that matter most in our lives or in our careers. His insight is always persuasive, sometimes stunning. A very careful book.

This fascinating book analyzes a topic almost never considered by economists, how social pressures modify choices among publicly visible actions. In particular, expressed "public opinion" may be unrepresentative of actual private beliefs, so a minor shock can easily set a bandwagon in motion. Thus political and social equilibria are far more fragile than is usually believed. In fact, almost all great revolutions have been more or less total surprises. The author's applications of the model--to the caste system in India, to the downfall of communism, and (unexpectedly!) to the affirmative action juggernaut in the United States--are gripping, insightful, and (with regard to the last issue) courageous.

Timur Kuran explores the devastating consequences to political discourses that derive from the simple unwillingness of intelligent individuals to say publicly what they believe privately. The United States may have constitutional guarantees for freedom of speech that were nowhere to be found in communist societies. But the eerie parallels that Kuran draws between the persistence of communism in Eastern Europe and the persistence of affirmative action at home should give even skeptical readers pause about the ability of our legal institutions to promote candid discussion of the major political issues of our times.
