Many "nudges" aim to make life simpler, safer, or easier for people to navigate, but what do members of the public really think about these policies? Drawing on surveys from numerous nations around the world, Sunstein and Reisch explore whether citizens approve of nudge policies. Their most important finding is simple and striking. In diverse countries, both democratic and nondemocratic, strong majorities approve of nudges designed to promote health, safety, and environmental protection—and their approval cuts across political divisions. In recent years, many governments have implemented behaviorally informed policies, focusing on nudges—understood as interventions that preserve freedom of choice, but that also steer people in certain directions. In some circles, nudges have become controversial, with questions raised about whether they amount to forms of manipulation. This fascinating book carefully considers these criticisms and answers important questions. What do citizens actually think about behaviorally informed policies? Do citizens have identifiable principles in mind when they approve or disapprove of the policies? Do citizens of different nations agree with each other? From the answers to these questions, the authors identify six principles of legitimacy—a "bill of rights" for nudging that build on strong public support for nudging policies around the world, while also recognizing what citizens disapprove of. Their bill of rights is designed to capture citizens’ central concerns, reflecting widespread commitments to freedom and welfare that transcend national boundaries.

This timely Research Handbook offers offers a comprehensive examination of the growing field of nudging and its impact on society. The editors, Cass R. Sunstein and Lucia A. Reisch provide readers with a detailed exploration of the theoretical and empirical work on nudging, as well as an understanding of current and likely future developments in the field. Divided into six key thematic parts, the Research Handbook covers everything from the foundations of nudging to its use in government and private organizations.

*Once again a New York Times bestseller! First the original edition, and now the new Final Edition* An essential new edition―revised and updated from cover to cover―of one of the most important books of the last two decades, by Nobel Prize winner Richard H. Thaler and Cass R. Sunstein More than 2 million copies sold Since the original publication of Nudge more than a decade ago, the title has entered the vocabulary of businesspeople, policy makers, engaged citizens, and consumers everywhere. The book has given rise to more than 400 “nudge units” in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful “choice architecture”—a concept the authors invented—to help us make better decisions for ourselves, our families, and our society. Now, the authors have rewritten the book from cover to cover, making use of their experiences in and out of government over the past dozen years as well as an explosion of new research in numerous academic disciplines. To commit themselves to never undertaking this daunting task again, they are calling this the “final edition.” It offers a wealth of new insights, for both its avowed fans and newcomers to the field, about a wide variety of issues that we face in our daily lives—COVID-19, health, personal finance, retirement savings, credit card debt, home mortgages, medical care, organ donation, climate change, and “sludge” (paperwork and other nuisances we don’t want, and that keep us from getting what we do want)—all while honoring one of the cardinal rules of nudging: make it fun!

The best-selling author of Simpler offers an argument for protecting people from their own mistakes.

Evangelism is about reaching out to others. Really? You think? Brace yourself. In Nudge, author Leonard Sweet sets out to revolutionize our understanding of evangelism. He defines evangelism as “nudge” – awakening each other to the God who is already there. Sweet’s revolution promises to affect your encounters with others, as well as shaking the very roots of your own faith. So brace yourself.

All over the world, private and public institutions have been attracted to “nudges,” understood as interventions that preserve freedom of choice, but that steer people in particular directions. The most effective nudges are often “defaults,” which establish what happens if people do nothing. For example, automatic enrollment in savings plans is a default nudge, as is automatic enrollment in green energy. Default rules are in widespread use, but we have very little information about how people experience them, whether they see themselves as manipulated by them, and whether they approve of them in practice. In this book, Patrik Michaelsen and Cass R. Sunstein offer a wealth of new evidence about people’s experiences and perceptions with respect to default rules. They argue that this evidence can help us to answer important questions about the effectiveness and ethics of nudging. The evidence offers a generally positive picture of how default nudges are perceived and experienced. The central conclusion is simple: empirical findings strongly support the conclusion that, taken as such, default nudges are both ethical and effective. These findings, and the accompanying discussion, have significant implications for policymakers in many nations, and also for the private sector.

Interventions aimed to change behavior (so called nudges) are becoming more and more popular among policymakers. However, in order to be able to effectively use nudges, it is important to understand when and why people find them acceptable. The objective of this thesis is therefore to improve the understanding of when nudges are judged to be acceptable. The thesis focuses on a model for behavioral change. The model contains two parts, nudge technique and acceptance of nudges. Nudge technique refers to how the nudge is designed to function in regard to psychological mechanism and functionality. The nudge technique part of the model is expanded and problematized from an ethical perspective in the first part of this thesis, by exemplifying psychological mechanisms behind different techniques and explaining why they might be intrusive to individuals’ freedom of choice. In the second part of this thesis it is discussed why acceptance is an important component of making nudging legitimate and effective. This is followed by a discussion of how acceptance is empirically measured. The empirical part of the thesis is based on four papers which all use a quantitative online survey approach to study the judgements of nudges from the general public. Paper 1 was a first attempt to measure whether nudges which are common in the nudge literature are acceptable interventions according to the general public. We found that the nudges that were categorized as pro-self were more likely to be rated as acceptable and less likely to be perceived as intrusive to freedom of choice compared to pro-social nudges. Furthermore, the effect of decision styles and worldview on acceptance was explored. In paper 2, we explored whether the difference between acceptance found for pro-social nudges and proself nudges could be increased by framing nudges as beneficial for society or individuals. The framing had no effect on acceptance but, as in paper 1, pro-social nudges were found to be more intrusive to freedom of choice compared to pro-self framed nudges. Moreover, different nudge techniques had different rates of acceptance even with the same explicit goal for the nudges. In paper 3, we examined whether the alternative to nudges affects the perceived acceptability and intrusiveness of default-changing nudge techniques. The alternatives given to the nudges were either to enforce the intended behavioral change with legislation or to do nothing at all in order to change the behavior. We find no difference in aggregated acceptance, however, the judgements vary depending on individuals’ worldview. Paper 4 explored if the choice architect’s (the creator/proposer of the nudge) political affiliation affects acceptance rating for proposed nudge interventions and legislation. We find that acceptance of both nudges and legislation increases with the level of matching between people’s political orientation and the choice architect’s political affiliation. Taken together, the findings suggest that there is more to creating an acceptable nudge than to merely take a nudge technique that was acceptable in one context and apply it in another. Moreover, nudges that are rated as more beneficial towards individuals compared to society at large are in general more likely to be found acceptable and less intrusive to freedom of choice. It is important to have knowledge about the target population (e.g. their decision styles, world-views, and political orientation) to avoid backfires when implementing nudges.

This book pursues the questions from a broad range of law and economics perspectives. Digital transformation leads to economic and social change, bringing with it both opportunities and risks. This raises questions of the extent to which existent legal frameworks are still sufficient and whether there is a need for new or additional regulation in the affected areas: new demands are made on the law and jurisprudence.

In recent years, a wave of reforms known as ‘nudges’ or ‘behavioural interventions’ have emerged in public policy and administration. ‘Nudge’ policies are created to lightly influence groups in society to change their behaviour, using behavioural insights to solve complex policy problems. Generally, behavioural approaches focus on the psychology underlying the implementation and effects of policies in practice. First published as a special issue of Policy & Politics journal, this book situates these reforms within a broader tradition of methodological individualism. With contributions from international scholars, it demonstrates that when behavioural policies expand their focus beyond the individual, they have the potential to better understand, investigate, and shape social outcomes.

This book asks several critical questions relevant to those interested in public policy: What is a nudge? What are the ethical implications of and justifications for nudges? Are we able to have nudges without affecting one’s freedom to choose? In what institutional context are nudges likely to work well and in what context are they likely to fail? The text explores several real-world instances of government attempts at successful choice architecture across a wide range of policy topics: internet privacy laws, environmental policy, education policy, the sharing economy, and creating a national culture. This approach also highlights the spontaneous and evolutionary nature of social institutions like culture and trust. Attempts from policymakers to generate these social institutions where they did not exist previously are unlikely to succeed unless they are aligned with the unique characteristics of the society in question. This raises the question of whether the seemingly successful policy interventions were even necessary. A few of the chapters in this book directly examine these issues through case studies of both Latin America and Singapore. Each chapter in this volume explores the ways in which individuals in society respond to attempts by policymakers to “nudge” them towards a specific outcome. Some chapters explore the theoretical arguments in favor of utilizing this behavioral policy approach. Others explore the feasibility and potential limitations of this approach to public policy. Several of the chapters apply market process theory to understand a particular case study where nudge policies have been put into practice. The chapters, authored by an interdisciplinary group of policy scholars, include discussions of internet privacy laws, the sharing economy, education policy, environmental policy, as well as social issues such as trust and culture.
