Culture change in organisations: why it almost always fails (and what actually works)

Over the past few years I have had a close look at dozens of culture change programmes. And I too once believed that the key lay in formulating the right core values, organising inspiring kick-offs and hanging the new mission statement on the wall of the canteen. Until I realised: none of those programmes ever delivered what they promised. Not because intent was lacking, but because one layer was missing. The behavioural layer.

Research tells us that around 60 to 70 percent of culture change efforts in organisations fail - or at least fall short of their intended goals.¹ The most commonly cited cause: employee resistance. But that is, as I keep learning, a misdiagnosis. The real cause is far simpler and at the same time far more uncomfortable: the context has never been designed to make new behaviour easier than old behaviour. And as long as that is the case, culture change in organisations goes nowhere.

What makes culture change so difficult

Let us start at the core. What is culture, exactly? Not the values on the wall. Not the mission in the annual report. Culture is what people actually do in practice. How they run meetings. Who speaks up and who stays silent. How mistakes are discussed. Whether there is room for dissenting voices. Whether managers are available to their teams or not. Culture is the sum of everyday behaviour - a thousand small choices per day that together form a pattern.

And here lies the first problem. If culture is behaviour, then culture change is behaviour change. And behaviour change is inherently difficult - for individuals, but squared for collectives.

Why? Because culture is synonymous with what we call Comforts in the SUE Influence Framework™: the collective habits, social norms and identity-linked behaviours that keep people anchored in their current behaviour. Comforts are the positive sides of existing behaviour - the ease, the familiarity, the social safety of doing-what-everyone-does. And comforts are remarkably sticky. Not because people are irrational or hate change. But because, as humans, we naturally prefer comfort over effort.

Culture change is not fighting resistance. It is fighting comfort itself.

There is something else at play too: the Fundamental Attribution Error. This is one of the most robust insights from social psychology:² we tend to explain other people’s behaviour through their character or attitude, while systematically underestimating the influence of the situation. Managers who say their team “is not open to change” or “is not embracing the new way of working” are making precisely this error. They are naming a property of people, when they should be naming a property of the context.

The right question is not: Why are our people so resistant? The right question is: What context makes old behaviour easier than new behaviour?

Good person, bad circumstances. That is the lens that changes everything.

The three most common mistakes in culture change

Mistake 1: Starting with values instead of behaviour

The first and most common mistake: starting a culture change programme by formulating or revisiting core values. We are transparent. We are innovative. We put the customer first. That kind of statement.

The problem? Values say nothing about behaviour. An organisation can list “transparency” as a core value while meetings still take place behind closed doors and bad news is only shared when it can no longer be avoided. Values are an abstraction; culture is concrete. And as long as you do not define which behaviours you want to see - specific, observable, repeatable - there is little point talking about values.

The behaviour-oriented question is not: What do we believe? But: What do we do - and what do we want to start doing?

Mistake 2: Informing instead of designing

The second mistake: the communication campaign as the primary intervention. Newsletters, town halls, a polished video from the CEO, a workshop on the new culture. I call this “design for disappointment”: you build a programme that looks good on paper but fundamentally fails because it relies on the idea that people will adjust their behaviour once they are well informed.

They do not. Information barely changes behaviour. We have known this for decades from behavioural science - and yet the informational approach remains the most widely used intervention in culture change programmes. Why? Because it is easy. It is easier to produce a communication plan than to design a behavioural context.

But context is everything. Whether someone displays the new behaviour depends almost not at all on what they know or believe - it depends on whether the environment prompts, rewards and repeats that behaviour.

Mistake 3: One big programme instead of moments that matter

The third mistake is the ambition to change everything at once. Culture change as a grand transformation, where every value, every behavioural pattern, every team and every layer of the organisation must be set in motion. The result is always the same: overload, fatigue, and after a year a quiet death.

An effective approach deliberately selects two or three key behaviours that are most defining for the desired culture. Behaviours that are visible, that occur regularly and that - if they change - create a flywheel effect for the rest. In behavioural science we call these the “Moments that matter”: the specific situations where the new culture needs to land.

Culture change through the lens of the Influence Framework

The SUE Influence Framework™ is a diagnostic model that makes visible the unconscious forces that determine whether people change their behaviour. Four forces are central: Pains and Gains drive change. Comforts and Anxieties keep people anchored in current behaviour.

Suppose an organisation wants to develop a more feedback-oriented culture. People should give and receive feedback more frequently, more directly and more constructively. What does that look like through the lens of the Influence Framework?

Pains (driving): Employees and managers are frustrated by misunderstandings that pile up, by problems that only surface late, by the feeling that real conversations are being avoided. The pain is there - it makes people receptive to change.

Gains (driving): The promise of a feedback culture is attractive: faster growth, better collaboration, fewer surprises, a sense of psychological safety. The gains are real and appealing.

Comforts (restraining) - this is where it breaks down: Current behaviour is comfortable. Withholding feedback is socially safe. Avoiding a difficult conversation is the path of least resistance. The social norm is “don’t rock the boat.” Nobody wants to be the disruptive force. And this comfort - the silence, the indirect behaviour, the polite detour - is not a lack of will. It is a collective pattern ingrained over years and confirmed anew every single day.

Anxieties (restraining): What if I hurt someone? What if feedback is received negatively? What if after an honest conversation I get a worse performance review? What if my manager sees this as criticism of their leadership? Fear of the social consequences of honesty is one of the most powerful restraining forces in organisations.

A culture change programme that only communicates the gains (“feedback is a gift!”) and fails to design away the comforts and anxieties is doomed to fail. It is like asking people to merge onto the motorway while the crash barriers are missing.

How behavioural design approaches culture change

The behavioural approach turns a classic misconception on its head. The classic view assumes you must first change the mindset, and the behaviour will follow. Train, inspire, persuade - and then hope that people start acting differently.

Robert Cialdini’s research demonstrates compellingly that it works exactly the other way around.³ Attitudes follow behaviour. When people display different behaviour - even if that is initially prompted or facilitated by the context - their attitudes and identity gradually adjust. Behaviour changes mindset, not the other way around.

This is the foundation of the behavioural approach to culture change. You do not start by changing what people think. You start by designing a context that prompts different behaviour.

A good example is how Basecamp handled the transition to fully remote working. Instead of expecting the informal social connection that the office offered - the conversations by the coffee machine, the spontaneous lunch, the shared jokes in the corridor - to simply disappear, they actively redesigned that connection. They created online channels for hobbies, for small talk, for non-work-related conversations. They replaced the comfort of physical proximity with a designed alternative. Not by communicating that remote could also be sociable - but by arranging the context so that sociability could continue to exist.

This is context design. And it is the core of what behavioural design adds to culture change.

The SWAC model offers four keys that are directly applicable to culture change in organisations:

• CAN - Make the new behaviour easy. As long as the new behaviour costs more effort than the old, people will choose the old. Defaults, simplified routines and a supportive social context make new behaviour more accessible. A feedback culture does not begin with a course on giving feedback - it begins with a dedicated slot in every team meeting where feedback is expected and normalised.
• WANT - Build social proof from respected colleagues. People watch what others do. When the people they respect display the new behaviour, the threshold drops. The question is not: how do you convince everyone at once? But: who are the informal influencers whose behaviour others follow?
• SPARK - Design trigger moments for cultural key moments. Behaviour changes at concrete moments, not in the abstract. Which moments are the moments that matter in your organisation? Those are the moments where you need to prompt and facilitate the new behaviour.
• AGAIN - Culture is habit. Systematic repetition is the only way. One-off interventions do not work. Behaviour change only sticks when the new behaviour is repeated often enough to become a new habit. And that requires a designed repetition structure - not a one-off programme.

The role of leadership in culture change

No discussion of culture change is complete without addressing leadership. And here too: most organisations fundamentally misunderstand the role of leaders in culture change.

Leaders are deployed as communicators of the new culture. They give speeches at the kick-off. They communicate the core values. They explain why the change is necessary. And then they expect the organisation to start moving.

But the science of social norms teaches us something different. People adjust their behaviour based on what they see others - and particularly people with status and standing - actually doing. Not based on what those people say. A leader who preaches “transparency” but never shows vulnerability reinforces the existing culture. A leader who emphasises “psychological safety” but ignores or punishes critical voices tells the organisation what the real norm is.

The difference between telling a culture and demonstrating a culture is the difference between a programme that fails and one that sticks.

Leaders are the most powerful context designers in an organisation - not through what they say, but through what they consistently do. Behavioural contagion is a real phenomenon: when leaders model the new behaviour, they lower the social threshold for everyone else to do the same.

In concrete terms, that means: leaders must be the first to display the new behaviour, and do so consistently, in the small everyday moments. Not once on stage - but in every meeting, every conversation, every decision. And they must identify the informal “cultural carriers” in the organisation: the people who inspire others, not because of their title, but because of their impact. Those people are the lever of every culture change.

Conclusion: culture change is context design

Culture change in organisations does not fail from lack of ambition, not from unwilling employees and not from poor communication. It fails because the context has never been designed to make new behaviour easier than old behaviour.

The behavioural approach reverses the classic sequence. You do not start with values - you start with behaviour. You do not start with communicating - you start with designing. You do not start with the whole system at once - you start with the two or three key behaviours that are most defining for the desired culture.

And above all: you start with the honest question of which comforts are holding the current culture in place. Which behaviour is currently easy, socially safe and familiar? And how do you design a context in which the new behaviour becomes those things too?

That is not a communication challenge. That is a design challenge. And behavioural design has the tools to answer it.
