Nudging in communication means redesigning the choice environment so that the desired behaviour becomes the easiest and most natural option. Instead of telling people what to do, you adjust how choices are presented: the order of options, the default setting, social cues, and the framing of your message. For communication professionals, nudging is one of the most effective strategies to move people from reading to doing.
Nudging is one of the most powerful instruments for communication professionals. By cleverly adjusting the way you present choices, you can steer behaviour without banning anything. Yet most communication departments still rely primarily on informing: explaining why something is important, hoping that understanding will lead to action. It rarely does.
In this article, we show you how nudging works in practice, which techniques are most relevant for communication professionals, and how you can apply choice architecture in your daily work: from internal communications to public campaigns.
What is nudging, exactly?
A nudge is a subtle intervention that steers people's behaviour in a predictable direction without restricting their freedom of choice. The term was introduced by behavioural economist Richard Thaler and legal scholar Cass Sunstein in their influential 2008 book Nudge.[1]
The key principle behind nudging is that behaviour is shaped far more by the environment in which decisions are made than by rational deliberation. People do not carefully weigh every option. They follow the path of least resistance. They choose the default. They do what others do. And they are disproportionately influenced by how information is presented.
For communication professionals, this changes everything. The impact of your communication does not depend primarily on the quality of your argument. It depends on how you design the choice environment around your message.

Why traditional communication falls short
Most communication strategies follow the same logic: if people knew what we know, they would do what we want them to do. This assumption has a name in behavioural science: the information deficit model. And it is consistently wrong.
Research shows that knowledge alone rarely changes behaviour. Smokers know that smoking is harmful. Employees know they should complete their timesheets on time. Citizens know they should sort their waste. The problem is not a lack of information. The problem is that behaviour is driven by System 1 (the fast, automatic, effortless thinking system), while information targets System 2: slow, conscious, and effortful.
This is precisely where nudging comes in. Instead of trying to convince people's System 2, you design the environment so that System 1 automatically steers towards the desired behaviour.
Five nudge techniques for communication professionals
Below are five proven nudge techniques that communication professionals can apply directly in their work.
1. Smart defaults
The default option is the single most powerful nudge there is. People overwhelmingly stick with the pre-selected option, regardless of what they know or believe. In the context of communication, this means: do not ask people to opt in to the desired behaviour. Make it the standard.
Practical examples: pre-register employees for a training session and let them opt out if needed. Set the sustainable option as the pre-selected choice on a form. Schedule the team meeting in the new format by default rather than asking people to choose between old and new.
2. Social proof
Social proof is the tendency to look at what others are doing, especially when we are uncertain. In communication, you use this by making the desired behaviour visibly normal.
Instead of explaining why people should complete a survey, communicate: "82% of your colleagues have already responded." Instead of arguing why a new policy matters, show that the majority of teams have already adopted it. The message is not why it matters. The message is that it is already happening.
3. Friction reduction
Every obstacle between intention and action, an extra click, a confusing form, an unclear next step, dramatically reduces the likelihood of the desired behaviour. This is what behavioural scientists call friction. And it is the silent killer of even the best communication campaigns.
Audit your communication for friction. How many steps does it take for someone to act after reading your message? Can you reduce that to one? Can you include a direct link instead of an instruction? Can you pre-fill the form? The less effort required, the more people will follow through.
4. Strategic framing
The framing effect describes how the same information leads to different decisions depending on how it is presented. Loss framing is particularly powerful: people are more motivated to avoid losing something than to gain something of equal value.
Instead of communicating the benefits of switching to a new system ("You will save 30 minutes per week"), frame the cost of not switching ("You are losing 30 minutes per week with the current system"). Instead of highlighting what people stand to gain from attending a session, highlight what they miss by not attending.
5. Timely prompts
Timing is everything in behavioural science. People are most receptive to new behaviour at moments of transition: a new job, a new quarter, the start of a project. These fresh start moments temporarily activate System 2 and create a window for change.
For communication professionals, this means: do not send your message when it is convenient for you. Send it when the recipient is most receptive. Monday morning is better than Friday afternoon. The first day of a new policy period is better than the third week. The moment someone joins a new team is better than a random Tuesday.
Nudging versus manipulating
A common concern: is nudging not just a polite word for manipulation? The distinction matters, and it is clear-cut.
A nudge preserves freedom of choice. People can always choose differently. The desired option is made easier, not mandatory. A manipulation restricts choice or deliberately misleads. Dark patterns in digital design (hidden opt-out buttons, confusing cancellation flows, pre-ticked consent boxes) are manipulations, not nudges.
Ethical nudging follows three principles: it serves the interest of the person being nudged, it is transparent about its intent, and it never makes the alternative option invisible or unreasonably difficult. As Richard Thaler himself put it: nudges should be easy to avoid. If someone needs to hire a lawyer to opt out, it is not a nudge.
Nudging in practice: three scenarios
To make nudging tangible, here are three scenarios that communication professionals regularly encounter.
Scenario 1: Increasing survey response rates
The traditional approach: send an email explaining why the survey is important and ask people to participate. Response rate: 25%.
The nudge approach: send a personal invitation with a pre-filled link (reduce friction). Include the line "73% of your team has already responded" (social proof). Set a clear deadline with a countdown (scarcity). Send a reminder at Monday 9:00 AM, not Friday at 17:00 (timely prompt). Response rate: 60%+.
Scenario 2: Driving adoption of a new tool
The traditional approach: communicate the benefits of the new tool, organise a training session, send follow-up reminders. Adoption after three months: 30%.
The nudge approach: make the new tool the default for all new projects (smart default). Remove access to the old tool for new tasks (friction on the old behaviour). Show a dashboard of teams already using it (social proof). Provide five-minute micro-tutorials at the moment of first use, not a full-day training six weeks earlier (timely prompt). Adoption after three months: 85%+.
Scenario 3: Encouraging attendance at a voluntary session
The traditional approach: send an invitation, explain the benefits, hope people sign up.
The nudge approach: auto-enrol people and allow them to opt out (smart default). Add "12 of your colleagues have already confirmed" to the invitation (social proof). Include a one-click confirmation link (friction reduction). Frame the session as "what you will miss if you do not attend" rather than "what you will learn" (loss framing).
Where to start tomorrow
Nudging does not require a complete overhaul of your communication strategy. Start with one campaign, one email, one internal announcement. Ask yourself three questions:
- What is the desired behaviour? Not "what do I want people to know" but "what do I want people to do?"
- What are the barriers? Where is the friction? What makes it easier to do nothing than to act?
- Which nudge can I apply? Can I change the default? Can I add social proof? Can I reduce friction? Can I reframe the message?
The shift from informing to nudging is not a rejection of communication. It is an evolution. The communication professional who understands behavioural science does not stop crafting messages. They start designing choice environments. And that is where the real impact lies.
Frequently asked questions
What is nudging in communication?
Nudging in communication means using insights from behavioural science to guide people's choices without restricting their options. Instead of telling people what to do, you adjust the choice environment: the order of options, the default setting, social cues, and the framing of your message. The goal is to make the desired behaviour the easiest and most natural choice.
How do you apply nudging in practice?
You apply nudging by redesigning the choice environment. Concrete techniques include: setting smart defaults (pre-selecting the desired option), using social proof ("80% of your colleagues already signed up"), reducing friction (fewer steps, simpler forms), strategic framing (presenting information in terms of what people stand to lose rather than gain), and using timely prompts at moments when people are naturally receptive to change.
What is the difference between nudging and manipulation?
The real difference is transparency and intent. A nudge preserves freedom of choice: people can always choose differently. Manipulation restricts choice or deliberately misleads. Ethical nudging works in the interest of the person being nudged, is transparent about its intent, and never makes the alternative option invisible or unreasonably difficult.
PS
At SUE, we see communication professionals make the same discovery time and again: the moment they stop trying to change what people think and start redesigning how choices are presented, their impact multiplies. Nudging is not a trick. It is a fundamental shift in how you think about the role of communication. From broadcasting information to designing environments in which the right behaviour happens naturally.
