Nudges and Choice Architecture
What is a Nudge?
A nudge is a subtle intervention in choice architecture that influences people's behavior in a predictable way without prohibiting any options or substantially changing economic incentives. It's designed to guide individuals toward making better, more informed choices while preserving their freedom to choose. Nudges are effective because they work with, rather than against, people's natural tendencies and cognitive biases. The goal is to make the desired choice the easiest or most appealing option.
Choice Architecture
Choice architecture involves structuring the environment in which people make decisions. Since every environment has features that affect people's choices, anyone who designs such an environment is a choice architect. This design can significantly influence the decisions people make, whether it's selecting a product, choosing a healthcare plan, or deciding to save for retirement. Effective choice architecture leverages an understanding of human behavior, including biases and cognitive limitations, to present choices in a way that guides individuals toward optimal outcomes. Just as graphic design uses visual elements to guide the eye and create a compelling user experience, choice architecture employs various techniques to influence decision
Nudge vs. Other Choice Architecture
A nudge is a specific type of choice architecture, representing a deliberate design to influence behavior without coercion. Unlike mandates or bans, nudges subtly guide individuals toward certain choices by making those options more appealing or easier to select. For example, placing stairs in a prominent location nudges people to use them by increasing their visibility and convenience, yet individuals still have the option to take the elevator. This maintains freedom of choice while encouraging a specific behavior.
Libertarian Paternalism
Libertarian paternalism seeks to promote beneficial choices while upholding freedom of choice. It operates on the idea that institutions or governments can steer people toward better behaviors without resorting to mandates or coercion. This approach acknowledges that individuals often make decisions that are not in their best interests due to cognitive biases or lack of information.
Instead of imposing strict rules, libertarian paternalism uses subtle interventions, known as 'nudges,' to influence behavior in a positive direction. These nudges are designed to make healthier or more responsible choices more appealing or easier to make, while still allowing individuals to opt for alternatives. For example, automatically enrolling employees in retirement savings plans while allowing them the option to opt-out has been shown to significantly increase participation rates. Other examples of nudges include placing healthier food options at eye level in cafeterias or using default settings on electronic devices that promote energy-saving modes, which can have a considerable impact on overall public health and environmental sustainability.
Example Nudges
Apple Clean Energy Charging: This feature delays charging the phone to 100% until electricity is most available, shifting demand away from peak hours. It is easily disabled if needed.
Perris Junk Food Ban: Perris banned junk food in checkout aisles in grocery stores, a nudge intended to reduce impulse purchases of unhealthy items. While candy is still available in the store, its removal from the checkout area is intended to change behavior.
Discussion on the Perris Nudge
Some argue that the Perris ban is a nudge because it is easy to avoid and the candy is still available elsewhere in the store. However, others suggest it could make it too inconvenient to buy candy, thus changing choices. Business owners may dislike such nudges because they restrict their ability to sell high-margin impulse buys.
How to Nudge: NUDGES
The book "Nudge" outlines how to implement effective nudges using the acronym NUDGES, each component playing a crucial role in choice architecture:
Incentives: This involves drawing attention to existing incentives without altering them. The goal is to make people more aware of the benefits or drawbacks associated with their choices, thereby influencing their behavior.
Example: Displaying real-time electricity usage on appliances is a nudge that doesn't change the cost of electricity but makes consumers more aware of their consumption, potentially leading to reduced usage.
Understanding Mappings: Clear communication is key to helping people make informed decisions. This involves making complex information more understandable and relatable.
Example: Translating kilowatts used into monetary cost provides a direct and easily understandable mapping that can influence energy consumption behavior.
Defaults: People often stick with pre-selected options (defaults) due to inertia or convenience. Setting beneficial defaults can guide behavior in a positive direction.
Example: Setting low energy settings as the default on new laptops encourages energy conservation from the outset. Google's payment of 20 \times 10^9 dollars a year to be the default search engine on Apple devices highlights the power and value of defaults in shaping user behavior.
Give Feedback: Timely and informative feedback can help people understand the consequences of their actions and adjust their behavior accordingly.
Example: Using paint that changes color as it dries provides immediate feedback, preventing the common error of re-painting areas that are already covered.
Expecting Error: Designing systems that anticipate and accommodate user errors can prevent costly mistakes.
Example: Designing credit card machines that accept cards inserted in either direction minimizes user frustration and prevents transaction failures.
Structure Complex Choices: When choices are complex and overwhelming, structuring them effectively can help people make better decisions. This can involve simplifying the number of options, providing recommendations, or using decision aids.
Example: In the UK, signs on the floor that say \"look right\" help pedestrians from other countries remember to look in the correct direction when crossing streets, reducing accidents.
Government Involvement
The UK was the first government to actively implement nudging concepts at the national level. The government established a Behavioural Insights Team (BIT), also known as the 'Nudge Unit,' to apply behavioral science to policy-making. This team has worked across various domains, including health, education, and finance, to design interventions that encourage citizens to make better choices.
In the United States, President Obama signed an executive order to integrate behavioral science insights into federal policies and programs. This led to the creation of the Social and Behavioral Sciences Team (SBST), which collaborated with various government agencies to develop and evaluate interventions based on behavioral science principles.
The SBST website indicates that the material is historical and frozen in time as of January 2

Why Nudges Work
Nudges work effectively because they respect individual autonomy while subtly steering choices toward better outcomes. People often resist direct instructions or mandates, but they are more receptive to interventions that preserve their freedom to choose. Nudges align with people's automatic systems, leveraging cognitive biases and behavioral
The Importance of Nudging
Many people want to improve their sleep, diet, and exercise habits. Nudges can assist by aligning with their automatic systems in a non-intrusive manner. Nudges work by making subtle changes to the environment which makes it easier for individuals to make better choices. For example, instead of implementing strict rules, individuals are given the autonomy to make decisions without
Examples of Nudges
The Urinal Fly: Placing a picture of a fly in urinals provides a target, proven to reduce spillage by 80% at Amsterdam Airport. A simple 2 sticker can significantly improve bathroom cleanliness by leveraging a basic psychological principle: people are more accurate when they have a target.
Encouraging Stair Use: Strategically placed signs prompt people to choose stairs over elevators, increasing physical activity. These signs often include calorie burn information or motivational messages, such as "Burn extra calories - take the stairs!"
Gym Towel Returns: Creative and engaging towel return systems in gyms prevent theft and encourage returns. Some gyms use gamification, offering small rewards or recognition for consistent towel returns.
Trash and Recycling Bins: Color-coded and clearly labeled bins guide people to correctly sort waste. Standardized symbols and instructions help reduce contamination and improve recycling rates.
Encouraging Stair Use: Signs encouraging people to take the stairs instead of the elevator.
Gym Towel Returns: Making towel returns more engaging to prevent theft or disposal.
Trash and Recycling Bins: Guiding people to put garbage and recycling in the right place.
