Libertarian Paternalism (Nudge Theory)

Libertarian paternalism is a decision framework that uses 'nudges' to influence people's behavior while preserving freedom of choice. It has been adopted by governments across the political spectrum as a bipartisan approach to policy.

THE IDEA

A New Path

Thaler and Sunstein argue that libertarian paternalism can appeal to conservatives and liberals: it seeks to influence choices while keeping alternatives available. They point to governments across the political spectrum that adopted behavioral approaches after the original publication of Nudge. The following institutional descriptions reflect their account at the time of writing.

In the United Kingdom, former Prime Minister David Cameron, the leader of the Conservative Party, embraced nudging and created the world’s first team devoted solely to this effort, officially called the Behavioural Insights Team, but often called the Nudge Unit.* In the United States, former President Barack Obama, a Democrat and a liberal, also embraced the basic idea, directed his agencies to adopt numerous nudges, and created a nudge unit of his own (originally known as the Social and Behavioral Sciences Team, and now called the Office of Evaluation Sciences). The United States Agency for International Development has an assortment of programs that use behavioral science and insights. In the years since the book was originally published, governments around the world, spanning the political landscape, have incorporated these and related ideas in an effort to make their programs more efficient and effective. There are behavioral insights teams or nudge units of various kinds in numerous nations, including Australia, New Zealand, Germany, Canada, Finland, Singapore, the Netherlands, France, Japan, India, Qatar, and Saudi Arabia. A great deal of relevant work is being done by the World Bank, the United Nations, and the European Commission. In 2020, the World Health Organization created a Behavioral Insights Initiative focusing on numerous public health issues, including pandemics, vaccination uptake, and risk-taking by young people.

Although the world seems to be becoming increasingly polarized, we continue to believe that libertarian paternalism can be a promising foundation for bipartisanship and for simple problem-solving. Better governance often requires less in the way of government coercion and more in the way of freedom to choose. Mandates and prohibitions have their place (and behavioral science can help to identify them), but when incentives and nudges replace requirements and bans, government will be both smaller and more modest. So, to be clear: this book is not a call for more bureaucracy, or even for an increased role of government. We just strive for better governance. In short, libertarian paternalism is neither left nor right. For all their differences, we hope that people with very different political convictions might be willing to converge in support of gentle nudges.

Part I

When to use it

  • Using behavioral insights to increase vaccination uptake during a pandemic.

  • Designing nudges to reduce risk-taking behaviors among young people.

  • Implementing default options to improve program efficiency in government services.

FROM THEORY TO EVERYDAY LIFE

In practice

01

UK's Behavioural Insights Team

Former Prime Minister David Cameron embraced nudging and created the world’s first nudge unit, officially called the Behavioural Insights Team, often called the Nudge Unit. This team applied behavioral science to improve policy outcomes.

02

US Social and Behavioral Sciences Team

Thaler and Sunstein describe Barack Obama directing federal agencies to use nudges and creating the Social and Behavioral Sciences Team, later called the Office of Evaluation Sciences in their account.

A MOMENT TO REFLECT

Put it to work.

  1. How might libertarian paternalism appeal to both conservatives and liberals?

  2. Can you identify a government policy that could be replaced with a nudge to reduce coercion?

  3. What are the limits of nudges? When might mandates still be necessary?
