A business anthropologist reveals how cultural intelligence is the essential tool for understanding human behavior

Why do people do what we do? To answer this question, many of us turn to psychology. But it’s not enough to understand how we think. We also have to recognize the influence of where and how we live. From the ways we bring up children and welcome guests, to the products we buy and how we spend our free time, our culture creates who we are.

Trailblazing anthropologist Oliver Sweet has spent decades using cultural insights to help businesses, governments, and NGOs achieve their goals—whether he’s working with the Gates Foundation to encourage South African men to get HIV tests or helping a pet food company break into a new market in Brazil. Now, in The Rules That Make Us, Sweet shows us how to strengthen our own cultural intelligence. Drawing on research conducted in thirty-five countries, he maps culture’s hidden rules: how it governs our behavior and creates our assumptions, how it’s shaped by technology, and even how it can help us predict the future. This book is an indispensable guide to an essential new way of understanding our families and colleagues, our customers and constituents, ourselves and our world. 

 

  • “From national culture to organizational culture, our lives are shaped by hidden rules that govern how we behave and what we believe. In this engaging new book, Sweet uncovers these rules and helps us understand how to recognize their influence. This is a must-read for anyone who wants to understand how the world really works.” 
    Erin Meyer, author of The Culture Map
  • The Rules That Make Us is a clear, compassionate, and much-needed book for our time. In an age obsessed with data and individual psychology, it reminds us that human behavior is never just about the person—it’s about the patterns, rituals, and unspoken rules of culture that make us who we are. With the eye of an anthropologist and the clarity of a storyteller, Sweet helps us see the water we all swim in—the invisible systems that shape our choices, our communities, and even our sense of self. This book doesn’t just explain culture; it restores our ability to see it—to notice what we have stopped noticing. It’s an elegant argument for why understanding people requires understanding the world they inhabit. I read it with gratitude and a sense of recognition: this is how deep seeing begins.” 
    Christian Madsbjerg, author of Sensemaking: The Power of the Humanities in the Age of the Algorithm
  • “Sweet does something rare: he captures cultural complexity without flattening it into easy answers. The evidence is rigorous, the thinking is nuanced, and the whole thing feels genuinely contemporary. People will still be referencing this in a decade … and more!” 
    Rob Scotland, head of brand marketing, Veo
