Behavior change frameworks are the bedrock of applied behavioral science. Designed by behavioral scientists for policymakers and industry leaders, these summaries of cutting-edge decision-making insights are essential for applying research in the public and private spheres. Frameworks distill strategies for influencing human decisions into simple, portable mnemonic devices or acronyms. This makes it possible for complex, theoretical insights about how people think and act to inform the practices of organizations across every industry and environment. To understand more about how these frameworks work in practice, check out our case studies.

Imagine your city launches a campaign to encourage bike commuting to free up road congestion at rush hour. You’re interested in giving it a go, but your commute is not very bike-friendly, your creaky old bike is uncomfortable, no one else at your office bikes to work, and it’s been raining for days. Now imagine a different scenario: you live on a great bike path, the city offers a rebate to upgrade your bike, your coworkers have started biking, and it’s early summer with a stretch of sunny days ahead. Suddenly, the idea of biking to work seems a lot easier, more appealing, socially encouraged, and perfectly timed. This is the power of the EAST Framework for motivating positive behavior change.

The Behavioral Insights Team (BIT) introduced the EAST Framework in 2012 as a concise guide for applying behavioral science in government and beyond. Rather than replacing existing policy tools, it helps decision-makers weave behavioral principles into the design of everyday systems—through defaults, feedback, incentives, and other evidence-based strategies aimed at making desired behaviors easier and more appealing. The EAST Framework is composed of four principles, which designate that a policy should be Easy, Attractive, Social, and Timely (EAST). Here’s a breakdown of the model’s key components:

Easy

In the EAST Framework, “E” stands for Easy: we are more likely to adopt behaviors that require minimal effort. In general, people tend to give up on tasks when faced with many obstacles. The EAST Framework provides techniques to combat this tendency. First, since people typically subscribe to default options, making the desired behavior the default state increases the likelihood it will be adopted. Similarly, policymakers can alter the levels of friction to make competing behaviors seem more or less difficult. By making the preferred decision easier to choose, they make the less preferred decisions more difficult.

Finally, when providing the public with information, the “Easy” part of the framework highlights the value of making messages clear and simple. Topics that are too complex or detail-oriented are likely to be ignored.

Attractive

In order for a policy to be taken up, the proposed behavior change must be attractive, appealing, and rewarding. Visual design elements like color, imagery, and personalization can help capture attention, while incentives such as small rewards, lotteries, or playful “gamification” features can make engagement feel worthwhile. When an intervention feels both interesting and meaningful, it naturally draws more participation.

Social

As social creatures, people typically enjoy being part of groups—this used to be necessary for survival. Therefore, we are highly influenced by the thoughts, approval, and behavior of others. By harnessing our reliance on other people’s approval, policymakers can influence behavior.

One technique rooted in the EAST Framework involves convincing people that the majority of others engage in the preferred behavior. This technique takes advantage of the bandwagon effect, which is our habit of engaging in activities and beliefs as they gain popularity.

Another social technique involves fostering communities and networks to hold individuals accountable. This technique works because groups develop social norms, which diminishes the amount of effort involved in fitting in with others. For example, weight loss communities minimize the difficulty of losing weight by holding each other accountable and fostering a sense of mutual responsibility. Similarly, the EAST Framework suggests that if we make an explicit social commitment—using commitment devices like pre-paying for a gym membership or publicly announcing a goal—we are more likely to follow through.

Timely

The timing of an intervention can also have a very important influence on public perception. After all, people’s perceptions are influenced by context and their individual circumstances. Moments of transition—starting a new job, moving homes, or becoming a parent—make individuals more open to change. Policymakers can take advantage of these “fresh start” moments by introducing programs when people are most receptive. Likewise, aligning costs and rewards with immediate consequences, rather than distant benefits, helps overcome short-term biases and encourages action today.

Furthermore, if a policy includes specific costs or benefits, it is important to acknowledge at what point someone will receive them. Unfortunately, many policies have high upfront costs, while the benefits created by the policy are not generated for years to come. For example, imagine a government is doing a much-needed expansion of its medical system. This policy, while important, will take many years to complete and will lead to an increase in taxes for the first few years. People are typically biased towards thinking in terms of their present well-being, so this overhaul, while necessary, might be unpopular due to its high immediate costs. Reducing instant costs or increasing immediate benefits can help with the uptake of programs.

Implementation Plan

To support the practical rollout of EAST-inspired initiatives, the Behavioral Insights Team recommends pairing each intervention with a structured plan of action. Many well-intentioned policies fail because they stop at inspiration rather than execution. The concept of “implementation intentions”, first proposed by Peter Gollwitzer, offers a way to bridge that gap by turning goals into specific, time-bound actions.

In this spirit, BIT encourages policymakers to move through four broad stages:

1. Clarify the goal. Define a concrete behavioral outcome and what success will look like in measurable terms.
2. Understand the setting. Study the surrounding systems and constraints to ensure the policy fits the lived realities of its audience.
3. Design and deliver. Develop the intervention and plan for its implementation, making use of behavioral insights where they add value.
4. Monitor and refine. Continuously test results, learn from data, and iterate to strengthen the intervention’s effectiveness over time.

This process highlights the same philosophy that underpins the EAST framework itself: simple, testable actions often make the difference between good ideas and real-world impact.

Thanks to the simplicity of the above components, the EAST Framework has been used across a wide variety of contexts and industries, from healthcare and education to workplace management. The framework successfully distills complex behavioral science concepts into intuitive, practical insights, helping policymakers optimize behavior change interventions based on decades of behavioral science research. While the framework continues to evolve—and may be somewhat limited in scope due to its simplicity—it remains an incredibly valuable tool for governments, businesses, and other organizations seeking to encourage the uptake of desirable behaviors.

Behavioral Economics: An economic approach that combines psychology with economics to understand how humans actually behave instead of how they ideally would. While traditional economics assumes that we are purely rational agents who successfully maximize value with access to the right information, behavioral economics acknowledges that our decisions often deviate from rationality.

Choice Architecture: The deliberate design of decision-making environments to influence the choices people make—without removing their options or outright restricting their freedom to choose. This can include various choice design strategies rooted in behavioral science, such as pre-filling information in a form to make it easier to submit, automatically enrolling people in certain programs unless they opt out, or positioning healthy foods at eye-level on grocery store shelves.

Nudge Theory: A behavioral science theory suggesting that subtle changes to the environment can influence people’s behavior in predictable ways. Nudges are specific design strategies intended to gently push people toward certain decisions, such as default options, reminders, message framing, and social proof. These nudges play a key role in implementing the EAST Framework.

Cognitive Load Theory: A framework that explains how the brain manages working memory, suggesting that the brain has a limited capacity to process information. When our mental capacity is overloaded, decision-making suffers. “Easy,” one of the core pillars of the EAST Framework, aims to minimize cognitive load and support better decision-making.

Framing: The process of crafting how information is presented to influence people’s decisions. It involves using words, stories, imagery, and numbers to shape how the audience interprets a message. From highlighting specific details and downplaying others to choosing words and images with known associations, framing can help align behavioral change campaigns with the core components of the EAST model.

In 2012, the UK’s Behavioral Insights Team was looking to simplify their MINDSPACE framework. The team found that policymakers struggled to remember the nine insights that make up the MINDSPACE model. In an effort to improve the memorability of their model, the BIT developed the EAST Framework. This framework was intended to provide policymakers with a list of the most effective influences on public behavior. The goal was to create a robust framework simple enough for any policymaker to implement easily in policy design.

The EAST Framework was formally published in 2014, coinciding with BIT’s transition from a purely government organization to a partly privatized consultancy.¹ At the time, BIT was a team of just 14 people. Now, the organization has grown to encompass 250 people across eight countries. Hundreds of behavioral science units have been created around the world to apply behavioral science insights to practical issues in the private and public sectors. Throughout this boom, the EAST Framework has remained remarkably relevant and influential, largely thanks to its simplicity.

However, BIT acknowledges that vast amounts of research have taken place since the framework’s initial publication. The organization released a revised and updated version in 2024, which retains the core principles of the original model but now includes new examples, research insights, and lessons learned from the past decade of implementation. For a deep dive exploring how the model has evolved, check out the podcast with BIT’s Chief Behavioral Scientist, Michael Hallsworth, and several authors of the original EAST Framework.

The Behavioral Insights Team

Founded in 2010, the Behavioral Insights Team (also known as the Nudge Unit) is a British social purpose organization that studies, develops, and implements behavioral science. Stationed in the UK, much of their work has been aiding the British government in implementing policies and improving public services by taking advantage of insights about human nature.³ Taking an empirical approach to policy, the BIT has been successful in helping the British government increase tax collection, improve electoral participation, and enable charitable giving. Recently, they have expanded their work to the United States, Canada, Australia, New Zealand, and Singapore.⁴

Richard Thaler

Economist and professor of behavioral science at the University of Chicago Booth School of Business, Thaler has been a foundational figure in the field of behavioral science. His work on nudge theory—and particularly his mantra “Make it easy”—played an important role in the development of the EAST Framework, with BIT crediting his ideas and insights as a key influence.⁹ In 2017, Thaler received the Nobel Prize in Economic Sciences for his contributions to behavioral science.¹⁰ 

The EAST model has been applied to both public and private sectors with significant real-world impacts. From strengthening policy design to helping marketing teams and improving workplace management, here are some key areas where the framework has been successfully applied.

Improved Policy Making

Since its conception, the EAST Framework has been fundamental for policy design. The Behavioral Insights Team has demonstrated the framework’s benefits for public policy in the United Kingdom in multiple situations. For example, the Behavioral Insights Team collaborated with the Department of Health, the National Health Service (NHS), and the Government Digital Service in 2013 to explore interventions to increase organ donations.⁹ For one month, people renewing their car tax online randomly received one of eight messages encouraging them to join the organ register. The most successful message variant asked: “If you needed an organ transplant, would you have one? If so, please help others.” BIT explains that this message worked because it drew on the social aspect of reciprocity—our inherent desire to maintain a sense of fairness in social exchanges.

The EAST Framework has been widely applied across a range of industries and contexts to encourage desirable behavior changes. Recently, both the UK and the Canadian province of British Columbia used techniques from the EAST Framework to support the development of their public health policies in response to COVID-19.^5,6 In fact, the framework has been one of the most widely adopted methods for applying behavioral science insights in practice.¹¹ According to Hallsworth, frameworks like EAST are likely popular because of their simplicity. From encouraging people to reduce electricity consumption to making meat alternatives more attractive and socially acceptable, simple and usable frameworks like EAST have a significant draw for policymakers seeking to improve the impact of government programs.

Applications in Marketing

The EAST Framework has also been valuable to marketing teams, as it has been shown to improve customer experience and click-through rates.⁷ From removing points of friction in the customer journey to using authentic customer reviews to endorse high-quality products, components of the framework can help marketers create better experiences for online users. At the same time, these strategies can nudge consumers along the sales funnel to boost conversions.

Importantly, incorporating behavioral science concepts like EAST into digital design and advertising has brought greater attention to ethical considerations in marketing. As more marketers use these insights to nudge consumer behavior, there has been a growing emphasis on transparency, consumer autonomy, and overall responsible design focused on helping customers achieve their own goals—rather than influencing behavior solely for the sake of profit.¹²

Workplace Management

On a slightly smaller scale, EAST has also been used for workplace management, particularly in health and safety initiatives. In a dedicated health and safety report, BIT outlines how to apply each component of the framework to keep people safe when they are at work, accompanied by examples from EAST-aligned interventions tested in real workplace environments.¹³ For instance, a Chinese garment factory reduced the amount of waste thrown on the floor by 20% simply by adding gold coin stickers (representing good fortune) to the floor. This intervention not only attracted attention to the issue but also made it culturally meaningful. Overall, the EAST Framework has become a cornerstone for implementing behavioral insights across industries and the world.

While the EAST Framework has numerous applications for guiding behavior and improving policy design, it’s not without its critiques and limitations. Debates about the framework’s primary focus on environmental behavioral drivers, its simplicity, and the ethics of influencing people’s decisions.

Focus on Choice Architecture

One of the main critiques of EAST is that the model relies heavily on choice architecture, or making changes to the environment to influence behavior, without much consideration toward individual attitudes or beliefs.¹⁴ For example, while linking a behavior to social norms can increase uptake, it may not lead to long-term change if individuals are not sufficiently motivated to alter their behavior. Underlying motivations, cultural influences, habits, and values can play a significant role in shaping what people do. While the EAST Framework has been successfully applied to create immediate shifts in behavior, interventions that fail to address deeper individual factors may fall short in encouraging long-lasting change. 

Limited Scope Across Behavior Change Contexts

Due to its simplicity, some argue that EAST may not be the most effective framework for tackling complex societal issues.¹⁴ Whether discussing climate change, crime, addiction, or unsustainable consumption, many of the challenges we’re facing today emerge from incredibly complex behaviors, calling for the use of more elaborate tools that account for the deeper drivers of behavior that are often overlooked by simpler frameworks.

However, BIT acknowledges these limitations and emphasizes that the EAST Framework is not intended for understanding the motivations behind behavior or encouraging reflective behavior change. Hallsworth is adamant that the model’s simplicity is, in fact, its strength.¹¹ While models with dozens of components might be attractive to skilled researchers, they can be discouraging for those facing practical problems, especially when these problems require immediate and affordable solutions. Just as the framework is meant to make behaviors easy and attractive, the model itself is digestible and relatively easy to implement, especially when compared to more complex approaches—even if these other tools might capture the complexity of applied behavioral science more comprehensively.

Ethical Considerations and Concerns About Manipulation

Like most other behavior change frameworks, the EAST model often generates ethical debates over concerns that it could be used for manipulation and social engineering. Let’s examine these concerns more closely. The EAST Framework employs multiple techniques, but ultimately is based on nudging. While nudging creates an environment in which people are free to choose, certain decisions are more cognitively taxing than others. In an intervention, for example, this might look like influencing people’s behavior in subtle ways—outside their awareness and without explicit consent. Due to concerns about its paternalistic tendencies and ethical ambiguities, nudge theory has been criticized for its potential to manipulate people and undermine individual autonomy.¹⁵

Proponents of nudge theory, however, argue that there is no way to make a choice neutral and that all choices harbor inherent framing and bias, whether explicit or implicit.⁸ We should therefore judge nudges based on their specific use rather than on discomfort with the idea of choice architecture. Applying the EAST Framework ethically requires prioritizing transparency, ensuring interventions align with individuals’ best interests, and preserving freedom of choice.

Nudging People Back to Work - Jobcentre Plus

A good example of a recent application of the EAST Framework is the BIT’s program for Jobcentre Plus, the UK government’s employment service agency.¹⁶ In 2012, Jobcentre Plus was struggling to bring down unemployment rates and called on the BIT for advice. In a small-scale pilot study, BIT worked with a team of Job Advisors to redesign the process individuals go through when they sign up to receive benefits and begin the job search. The intervention involved several changes rooted in the EAST Framework to nudge people back to work:

1. They made the benefit sign-up process easier by reducing the number of forms involved.
2. They made the program more attractive by personalizing advisors to each individual.
3. They made the process more social by having job seekers commit to weekly advisory meetings.
4. They made it more timely by having job seekers start to make plans on day one about getting back to work.

The results of the pilot study were promising, showing around a 5% increase in job-seekers exiting the benefit program. While this change may seem small, it is considered a substantial effect in this policy area.¹⁶ Researchers went on to refine and test the intervention across 12 Jobcenters in the UK, finding that the simple and low-cost interventions also worked very well when scaled up. Following these trials, BIT supported the training of 25,000 Job Advisors with the new process and worked with the Department for Work and Pensions to get the interventions into all Jobcenters, anticipating that the changes would help hundreds of thousands of people return to work.¹⁷

The EAST Framework for Encouraging Electricity Conservation

The EAST Framework has also been applied to reduce energy consumption across various studies and real-world trials.¹⁸ For example, in two large Swiss studies, around 80% of households and businesses stuck with renewable energy packages when these were presented as the default rather than an opt-in option.¹⁹ This intervention shows the powerful influence of making desired behaviors easy, removing the friction involved in actively choosing the target behavior and instead positioning it as the path of least resistance.

In another study, electricity company customers who were shown how their energy usage stacked up against their neighbors ended up decreasing their own energy consumption.¹⁸ This intervention targeted the social principle of the EAST model by sharing social norms around energy consumption, nudging consumers to adjust their behavior to align with what others were doing.

In yet another study, one company sold more energy-efficient appliances when it provided customers with the estimated lifetime energy costs of various options while they were shopping.¹⁸ Presenting these numbers not only simplified the decision-making process by translating complex long-term savings into clear comparisons, but also made energy-efficient options more attractive by highlighting their monetary benefits. This intervention was also timely, encouraging behavior change at the precise moment when people were making purchasing decisions—when they were most receptive to choosing something different from the status quo.

Each of these interventions showcases how foundational behavioral science insights used in the EAST Framework can encourage sustainable choices without coercing consumers or restricting their options. By making behaviors easy, attractive, social, and timely, interventions rooted in EAST can help nudge people toward sustainable actions that support broader environmental goals.

Nudges Work (and practitioners know exactly how well)

If you are interested in better understanding how nudges work, this article features experts Dr. Elizabeth Linos and Dr. Stefano DellaVigna, who discuss the effectiveness of nudging, how it works, and what to watch for in the field going forward.

Nudges: Social Engineering or Sensible Policy?

In this piece, TDL contributor Jared Celniker dives into the ethical argument surrounding nudging. Specifically, he focuses on the importance of transparency and intent behind choice architecture, the partisan divide on nudging, and its effectiveness in promoting social good.
