The Business Skill No One Is Talking About Enough
In a world saturated with data analytics, AI-powered insights, and performance marketing, one skill continues to be chronically undervalued by organizations of all sizes: cultural intelligence. Yet according to Oliver Sweet, a business anthropologist and head of ethnography at Ipsos — one of the largest research agencies in the world — understanding culture isn't a soft skill or a nice-to-have. It is the foundational framework through which every human decision, purchase, and belief is made.
Sweet's new book, The Rules That Make Us: How Culture Shapes the Way We Act, Think, Believe, and Buy, makes a compelling case for why companies and governments that ignore cultural intelligence do so at their own peril. Drawing on two decades of fieldwork across global markets, Sweet offers a fresh, anthropologically grounded perspective on why culture should sit at the center of every business strategy.
What Is Cultural Intelligence, and Why Does It Matter?
At its core, cultural intelligence is the ability to recognize, understand, and adapt to the cultural rules that govern how people live, think, and make decisions. Culture, as Sweet defines it, is our shared way of living. It's the invisible operating system running beneath every social interaction, every consumer behavior, and every organizational dynamic.
When businesses fail to account for culture, they often misread their audiences entirely. A product that resonates deeply in one market can fall completely flat — or worse, cause offense — in another, not because of poor quality, but because of a failure to understand the cultural rules shaping consumer expectations. Cultural intelligence bridges that gap. It transforms assumptions into understanding and generalizations into genuine insight.
For Sweet, this isn't theoretical. As head of ethnography at Ipsos, he and his team literally live alongside communities around the world, observing how people actually behave rather than how they say they behave in surveys. It's a methodology that repeatedly reveals blind spots that conventional research misses.
Culture Is No Longer Linear — It Is Divergent
One of Sweet's most provocative and important insights is that the old model of how culture evolves is no longer accurate. For most of the twentieth century, culture followed a relatively predictable linear path. Trends would emerge in niche or subcultural spaces — in music scenes, fashion communities, or youth movements — and then gradually flow outward into mainstream adoption. Marketers and anthropologists alike could observe the edges of culture and reliably predict where the center would move next.
That model is broken. Sweet argues that culture today is divergent rather than linear. Digital platforms have shattered the idea of a single mainstream. Instead of culture converging toward shared norms, it is splintering into countless parallel micro-worlds, each with its own aesthetics, values, language, and rules. TikTok communities, Reddit subcultures, fandoms, and ideological tribes all operate simultaneously without any single one dominating or absorbing the others.
This has profound implications for businesses. Companies that still think in terms of a single target audience or a universal consumer truth are operating with an outdated map. The territory has fundamentally changed, and cultural intelligence is what allows organizations to navigate it without getting lost.
Why Companies That Invest in Cultural Intelligence Win
The business case for cultural intelligence is not abstract. Organizations that develop genuine cultural fluency consistently outperform those that rely solely on demographic data or behavioral metrics. Here's why:
- They build more authentic brand relationships. When a brand understands the cultural values and unspoken rules of a community, it can communicate in ways that feel genuinely resonant rather than tone-deaf or pandering. Authenticity in this context isn't a branding aspiration — it's a cultural competency.
- They avoid costly missteps. Some of the most damaging brand failures in recent history have been the result of cultural ignorance — campaigns that inadvertently violated cultural norms, product names that carried unintended meanings in local languages, or messaging that ignored the lived experiences of a target community. Cultural intelligence is, among other things, a powerful form of risk management.
- They identify opportunities others miss. Because cultural intelligence requires looking at behavior from the inside out rather than the outside in, it surfaces needs, desires, and tensions that traditional market research overlooks. These gaps are often exactly where the most significant growth opportunities lie.
- They build more effective teams. Cultural intelligence isn't only externally facing. Organizations that cultivate it internally foster more inclusive, adaptive, and high-performing teams — teams that can collaborate across difference rather than being stymied by it.
How to Start Building Cultural Intelligence in Your Organization
Sweet's work at Ipsos suggests that developing cultural intelligence is not a one-time exercise but an ongoing practice. It requires curiosity, humility, and a willingness to spend time observing the world as others experience it. For businesses looking to take their first steps, this means moving beyond focus groups and surveys toward more immersive, ethnographic approaches — spending time in the environments where your customers actually live, work, and make decisions.
It also means resisting the temptation to confirm what you already believe. The most dangerous assumption in cultural research is that your own cultural lens is neutral or universal. Every researcher, strategist, and executive carries cultural biases that shape what they notice and what they dismiss. Genuine cultural intelligence begins with acknowledging that blind spot.
Training teams to ask better questions, partnering with cultural consultants or anthropologists, and building diverse research panels that reflect the actual complexity of your markets are all practical starting points. But perhaps most importantly, it requires leadership that treats cultural insight as strategic intelligence rather than a creative afterthought.
The Bottom Line: Culture Is the Context for Everything
Oliver Sweet's central argument is both simple and radical: you cannot truly understand why people do what they do without understanding the culture they inhabit. For businesses, that means cultural intelligence is not a department or a diversity initiative — it is a core competency that shapes product development, marketing strategy, organizational design, and long-term growth.
As culture continues to fragment and diverge at unprecedented speed, the companies that thrive will be those that invest in understanding not just what people are doing, but why — and what invisible cultural rules are guiding them every step of the way. In that sense, the lessons from The Rules That Make Us are less a guide to anthropology and more a blueprint for building businesses that are genuinely fit for the world as it actually is.
