The Invisible Force Driving Every Business Decision
There is a force shaping every purchase your customers make, every decision your employees take, and every message your brand sends into the world. It is not data. It is not technology. It is not even price. It is culture. And according to business anthropologist Oliver Sweet, most companies are profoundly unprepared to understand it.
Sweet is the head of ethnography at Ipsos, one of the largest research agencies on the planet. He has spent more than two decades studying how cultures operate across the globe, advising companies and governments on how they can become more culturally relevant. His new book, The Rules That Make Us: How Culture Shapes the Way We Act, Think, Believe, and Buy, distills those insights into a compelling argument: if you want to understand your customers, your colleagues, or yourself, you must first understand the cultural rules you all live by.
In a business world obsessed with quarterly metrics and algorithmic targeting, that argument might sound soft. It is anything but. Cultural intelligence—the ability to recognize, interpret, and respond to the unwritten rules that govern human behavior—is rapidly becoming one of the most valuable competencies a business can develop. Here is why.
Culture Is No Longer Linear—And That Changes Everything
When Sweet first began studying culture twenty years ago, the landscape was relatively predictable. Culture moved in a recognizable direction. Trends began at the edges, in subcultures and niche communities, and then migrated toward the mainstream. Marketers and brand strategists could monitor those edges, identify what was coming, and position themselves accordingly. The pipeline was clear.
That pipeline no longer exists in the same form. Culture today is divergent rather than linear. The internet, and social media in particular, has shattered the old model of cultural diffusion. Instead of one mainstream culture gradually absorbing subcultures, we now live in an era of simultaneous, competing cultural realities. Different communities—sometimes living in the same city or even the same household—operate according to entirely different sets of values, aesthetics, and assumptions about what is normal.
For businesses, this divergence creates both risk and opportunity. The risk is that a campaign or product that resonates powerfully with one cultural group can feel tone-deaf, offensive, or simply irrelevant to another. The opportunity is that brands capable of understanding and navigating multiple cultural contexts can build far deeper loyalty with their audiences than brands relying on broad, generic messaging ever could.
What Cultural Intelligence Actually Means in Practice
Cultural intelligence is not the same as cultural awareness. Awareness means knowing that differences exist. Intelligence means knowing how to act wisely in the presence of those differences. It requires curiosity, humility, and a genuine willingness to suspend your own assumptions long enough to understand someone else's world.
In a business context, cultural intelligence shows up in several concrete ways:
- Product development: Understanding why a product succeeds in one market and fails in another often comes down to whether it fits the cultural logic of its users—not whether it has the right features or the right price point.
- Marketing and communication: The most technically sophisticated campaign will fall flat if it speaks to values or assumptions that its audience does not share. Cultural intelligence helps communicators identify not just what to say, but how meaning is made in a particular context.
- Leadership and organizational culture: Multinational teams frequently struggle not because of skill gaps, but because of unspoken cultural differences in how authority, feedback, time, and collaboration are understood. Leaders with cultural intelligence can bridge those gaps rather than inadvertently widen them.
- Customer experience: The way a customer expects to be treated—what feels respectful, efficient, warm, or professional—is deeply culturally shaped. Businesses that recognize this can design experiences that genuinely feel right to their customers rather than just functional.
Ethnography: The Research Method That Gets Beneath the Surface
One reason cultural intelligence remains undervalued in many organizations is that the dominant tools of business research—surveys, focus groups, A/B tests—are not well designed to capture it. These methods are excellent at measuring what people say and what they do when directly observed. They are far less effective at uncovering why people behave as they do, or at revealing the cultural assumptions so deeply embedded that people do not even think to mention them.
This is where ethnography, the core methodology of anthropology, becomes invaluable. Ethnographic research involves spending extended time inside the lived experience of the people you are trying to understand—observing behavior in context, listening carefully, and resisting the urge to interpret everything through your own cultural lens. It is slower and messier than a survey. It is also dramatically richer.
Sweet's work at Ipsos applies this approach at scale, helping global organizations move beyond demographic data and behavioral analytics toward genuine cultural understanding. The insight is not simply that people in different countries behave differently. It is that those differences are systematic, meaningful, and learnable—if you are willing to do the work.
Why This Matters More Right Now
The business case for cultural intelligence has never been stronger. Globalization has put companies in contact with more cultural contexts than ever before. Digital platforms have compressed those contexts into a single, constantly churning feed where cultural misreads become public and permanent in seconds. Meanwhile, consumer expectations for authenticity and genuine understanding have risen sharply—audiences are increasingly skilled at detecting when a brand is performing cultural fluency rather than actually possessing it.
At the same time, internal workplace cultures are under scrutiny as organizations grapple with questions of inclusion, belonging, and psychological safety. These too are cultural questions, and they require cultural intelligence to answer well.
The Competitive Advantage Hidden in Plain Sight
Oliver Sweet's core argument is simple but profound: culture is the operating system of human life. It shapes what we want, how we make decisions, what we trust, and what we reject. Businesses that invest in understanding that operating system will always have an edge over those that treat human behavior as a set of variables to be optimized without ever asking what those variables actually mean.
Cultural intelligence is not a soft skill. It is a strategic capability—one that sits at the intersection of empathy, curiosity, and rigorous inquiry. In a world where culture is no longer linear, where every audience is fragmented and every assumption is contestable, it may well be the most important competitive advantage your organization is not yet developing.
The rules that make us are everywhere, once you know how to look for them.
