How Language Creates Culture

By Joe Newsum

Language creates culture. It always has.

And yet when organizations set out to build organizational culture today, they start with values, behaviors, and training programs. They skip the one thing that has always come first.

Everything on this page is an argument about a single chain, so here it is before anything else.

The Causal Chain, Link by Link

That is the chain read forward, which is how it explains what already happened in your organization. Read it backward and it becomes something more useful.

Start at the end. What performance do you actually need? Then work back a link. What kind of culture produces that performance? What behaviors, repeated by enough people for long enough, add up to that culture? What would people have to be thinking for those behaviors to be the obvious thing to do, rather than the thing they were told to do? And finally, what language would put that thinking in their heads in the moment it matters?

That last question is the one almost nobody asks. Most culture work jumps from the performance gap straight to a list of desired behaviors, skipping the two links that actually determine whether any of it happens.

And there is a reason the chain has to run through thinking rather than around it. To think differently about something, you have to change the language in your own head first. Not what you say out loud. The words you use to describe the situation to yourself. A hard conversation becomes a confrontation or a chance to get something straight depending on which of those two phrases you reached for, and you reached for it before you walked in the room.

Now scale that up. When enough people share the language they use in their own heads for the same situation, they start thinking about it the same way. Thinking alike, their behavior gets consistent without anyone coordinating it. And consistent behavior, repeated at scale over time, is culture.

Read the chain forward to understand your culture. Run it backward to build one.

Language Comes Before Thinking in Every Discipline and Craft

The rest of this page is the case for that chain, starting with the link people find hardest to believe: that the language comes before the thinking rather than after it.

Think about any discipline you have learned or watched someone learn. The learning is not primarily content. It is language. A medical student does not learn to think like a doctor and then pick up medical vocabulary. They acquire the vocabulary, and that is what makes them think like a doctor. A carpenter does not learn to think like a carpenter and then pick up joinery, grain, and load-bearing. They learn the words, and the wood starts looking different.

An engineer. A chef. A lawyer. A musician. A plumber. Every practitioner of every craft learned the language of their field first. The thinking followed. The skill followed. The identity followed. You cannot pull the language out of the thinking. They are the same thing.

The only thing that truly separates us from our ancestors sitting around a fire ten thousand years ago is language, and the accumulated thinking and culture that language made possible.

How Language Creates a Completely Different Culture: the Dental Office

That is the chain running through one person at a time. Now watch one sentence run it through an entire team.

Two dental offices, same objective: efficiency and patient volume.

The same chain, running in a dental office.

The first tells its team to drive patient visits per day. That language builds a mental model of throughput. Speed. Getting people in and out. Every decision the team makes, consciously or not, optimizes for volume. The patient becomes a unit of production and the experience turns transactional.

The second tells its team that one of the most important things they do is be mindful and respectful of their patients’ time. Completely different mental model. Now the team is thinking about being on time, communicating delays, never letting someone sit in a waiting room feeling forgotten. Every decision optimizes for respect.

Same objective. Same metric underneath. Two entirely different cultures. And the beautiful part is that the office genuinely committed to respecting patient time almost certainly sees more patients per day, because people come back, refer friends, and stop cancelling.

That leader did not post a metric on the wall. They handed their team a way of seeing the work, and the behavior followed. That is culture built on purpose, and it has nothing to do with values.

Where in your organization would a different way of describing the work change how your team thinks about it?

The Observation That Started Everything: McKinsey and the Power of Shared Language

I spent five years at McKinsey, and one thing about it never stopped nagging at me.

The firm had one of the strongest problem-solving cultures on the planet. Every consultant, in every office, in every country, came at problems the same way. A new analyst in London could fly to Singapore on their second project and function immediately, because everyone in that room was thinking with the same framework. Tens of thousands of people across dozens of countries, more coherent in how they thought about problems than most fifty-person companies.

And there was almost no formal training on problem solving. No courses. No certification. No workshops. Just five questions, asked at the start of every project, repeated on every project, in every office, for decades.

1. What is the client really trying to solve? What is the problem statement in the form of a question?

2. What are the prioritized hypotheses we need to prove or disprove?

3. What is the MECE hypothesis tree, mutually exclusive and collectively exhaustive, with no gaps and no overlaps in our thinking?

4. What analysis will prove or disprove the hypotheses?

5. What is the storyboard for the final presentation?

Five questions, repeated until they became the default way every consultant approached every problem. And traveling alongside them, a vocabulary: The Pyramid Principle. So What. Obligation to Dissent. Syndication. Followership. Answer First. Workplan. Boil the Ocean. Hypothesis-driven.

Every one of those is a cognitive tool, not jargon. A shared way of perceiving a situation that every consultant carried into every engagement. McKinsey had done something no business school or training program managed. It took the scientific method, applied it to business problems, and gave the method language precise enough to travel across tens of thousands of people without a single mandatory course.

McKinsey did not set out to build a culture. They set out to build a shared language. The culture was the result.

That observation is where everything else in my thinking started. If language built that without anyone trying to build a culture, what could it build if you were deliberate about it?

Where in your organization have you seen shared language produce consistent behavior without anyone managing it?

The Rice Proof: How Language Shapes What Is Perceivable

So the pattern holds at one person, one team, one firm. The reason it holds is what language does to perception itself.

Here is the clearest demonstration of how language shapes perception, thinking, and even enjoyment. Japanese has roughly 7,000 expressions for rice, by the count of researchers at Japan’s National Agriculture and Food Research Organisation, spanning the grain itself, its appearance, its aroma, its taste, its texture, and its preparation. Because they have that vocabulary, Japanese people perceive, think about, and enjoy rice in ways an English speaker simply cannot.

Every term is a mental model. More terms mean more distinctions to taste, more ways to cook, more dimensions to enjoy. The same grain. An entirely different reality. Japan has professional rice sommeliers who deploy this vocabulary the way a wine expert deploys theirs, making distinctions that cannot exist without the language to hold them. The language did not describe the culture around rice. It created it.

Rich language changed what one person can perceive. Shared language is what lets a group perceive together. And a group perceiving together is the beginning of a culture.

Language shapes what is perceivable. What is perceivable shapes what is thinkable. What is thinkable shapes what is possible.

What language does your organization have for feedback? For accountability? For running a great meeting? If the answer is vague, the thinking is vague, and so is the behavior.

The Science Behind How Language Shapes Thinking and Behavior

This is not a consulting theory. It is basic cognitive science, and it holds at three levels: the culture, the conversation, and the single brain.

Start with the culture-level frame. The Sapir-Whorf hypothesis, or linguistic relativity, holds that the language people use shapes what they can perceive and think, and decades of research bear it out: language shapes and biases perception, attention, memory, and judgment. The words available to you shape the thoughts available to you.

George Lakoff’s framing research takes it further. Language does not only communicate ideas, it activates cognitive frames that decide which arguments are even thinkable. Every word evokes a frame, and the frame does its work before the person notices they are thinking. Change the language, change the frame. Change the frame, change what is possible to think.

Uri Hasson’s neural coupling research at Princeton shows what shared language does between two people. When a speaker and listener share the same language and frames, the listener’s brain activity mirrors the speaker’s, and the tighter the coupling, the greater the comprehension. When they do not share a language, the coupling disappears. Shared language is not just communication. It is the mechanism by which two brains align.

And the affect labeling research at UCLA shows it inside one brain. When people simply put a feeling into words, activity in the amygdala measurably drops and the prefrontal control regions engage. Naming an experience changes the brain’s response to it. Cognitive behavioral therapy runs on the same premise: change the language someone uses to describe their experience and you change how they think about it, and therefore what they do.

Your Company Needs Its Own Language

If language shapes thinking, and thinking shapes behavior, and behavior repeated at scale becomes organizational culture, then the highest-leverage move in any culture change is not better values, better training, or better measurement. It is changing the language.

Every group on this page has one. Doctors, carpenters, McKinsey. What they share is not that they talk a lot. It is that they hold a defined, specific vocabulary that every member actually uses, and that vocabulary does their thinking for them before they know they are thinking.

Most companies do not have one. They have jargon, which is a different thing. Acronyms, product code names, org-chart shorthand, the internal words for internal machinery. Jargon names things. A lexicon shapes how people see them. You can be fluent in a company’s jargon and still have no idea how anyone there is supposed to give hard feedback, disagree with a superior, or own a missed commitment.

So an intentional culture starts with a decision most companies never make: to be deliberate about the language. Not to let it accumulate out of whoever happened to be in the room over the last twenty years, but to choose it.

And it is not one list on one wall. A company language runs at levels. There is language everyone shares, whatever their role. There is language a function needs that nobody outside it does. There is language for the seams between functions, which is where most organizations lose the most. And there is language anchored to the activities that actually fill the week: how a meeting runs, how feedback gets given, how a decision gets made, how a missed commitment gets handled. I go deeper into each of these levels on the four types of commitments.

Built deliberately, at every one of those levels, that language becomes the one thing a competitor cannot copy. It is not a program or a policy. It is how several thousand people think.

This is why Culture by Commitment starts with language, and specifically with behavioral commitments: precise, verb-based statements that give people the exact words for the moments that matter most. Values describe a destination. Language tells people how to think when they get there.

One last truth. Changing the language of a company is really hard. It takes massive intentionality: leaders modeling the language in every meeting, repetition long past the point where it feels reasonable, holding on through the stretch where it still sounds like a program instead of how people here talk. McKinsey got there by asking the same five questions for decades.

But once the language takes hold, the chain runs itself. The thinking shifts. The behavior follows. The culture sets. And the payoff is an enduring company, one that grows its people and the bottom line, year after year.

Language first. Everything else follows.
