This one was fun to make: A Huffington Post multimedia slideshow illustrating the 8 culture clashes, plus a scorecard readers can use to figure out how independent and interdependent they tend to be. PLUS: pics of Angelina Jolie, Jennifer Lawrence, and LL Cool J, not to mention video of Michael Moore and Merida. Hope you enjoy this one as much as we do!

The Washington Post named CLASH! one of “Eight Books to Make You Smarter” on its innovator’s summer reading list. “This might just be the perfect summer book to read before a family vacation to visit the in-laws,” wrote Dominic Basulto. “Any book that gets props from Amy Chua of ‘Tiger Mother’ fame is worth reading to understand the deep cultural conflicts that determine how we raise our kids and who we choose to govern us.”

Kara Platoni of Stanford Magazine sat down with Hazel and Alana to discuss Clash! in “About Our Antagonisms.” Among the morsels, Hazel talks about the Japanese art vendor who praised her for picking out the watercolors “that all the American women like,” and Alana reveals “an excellent project for the 21st century.”

Psychology Today profiles CLASH! in its May 2013 issue under the headline “The Real Culture Wars.” Journalist Matt Huston writes about three trade-offs that people make when using their independent versus interdependent sides.



This book is a passkey that opens many doors. Using one simple principle, Clash! explains some of the most bedeviling cultural divides in our workplaces and communities.  It’s mandatory reading for teachers, managers, and parents who want to raise their kids to succeed in a multicultural world.”

Chip Heath, PhD, coauthor, Decisive: How To Make Better Choices in Life and Work and Switch: How To Change When Change Is Hard

What a brilliant, eye-opening book!  Filled with insight, and based on fascinating original research, Clash! offers a way to understand and break through some of the deepest cultural divides of our time. It’s a page-turner — fun, witty, engagingly written.”

Amy Chua, author of Battle Hymn of the Tiger Mother

If you fear that cultural, political, and class differences are tearing America apart, read this important book to learn how we can turn some of our differences into strengths.”

Jonathan Haidt, PhD, author of The Righteous Mind

Clash! offers deep insights into how our cultures and culture clashes make us who we are, and how that matters for success in the 21st century. Everyone should read this book.”

Carol S. Dweck, PhD, author of Mindset

In these days of heedless enthusiasm for gene maps and brain scans, Clash! reminds us that human beings are, above all, culture-bearing, culture-sharing, and culture-shaping animals. This thoroughly engaging book shows that to know a person, one must know a culture.”

Barry Schwartz, PhD, author of The Paradox of Choice and Practical Wisdom

Better than any book I know, Clash! illuminates the cultural influences in our everyday lives and how they underlie the major identity clashes of our times. This delightfully written book also imparts a better understanding of ourselves.”

Claude Steele, PhD, author, Whistling Vivaldi: How Stereotypes Affect Us and What We Can Do

A brilliant and highly accessible exposition of new scientific findings about profound cultural differences. As the world grows smaller and flatter, the wisdom of Clash! will prove essential for effective functioning.”

Richard E. Nisbett, PhD, author, Intelligence and How to Get It

Finally! An entertaining and scientifically rigorous explanation of how our cultures work on us and how we can work on them. Clash! is a must-read for crafting effective personal change strategies that work within and across most cultures.”

Philip Zimbardo, PhD, author, The Lucifer Effect

In the conflict of cultures lies, paradoxically, the ability to construct a self with integrity, agility, and the potential to grow in ways previously unimagined. Full of good science and sage advice, Clash! provides the evidence and strength to approach the hard question, “Who am I?”

Mahzarin Banaji, PhD, coauthor, Blindspot: Hidden Biases of Good People

In this eye-opening guide to becoming a more complete person in a divided world, difference (ethnic, religious, racial, political, gender) is a virtue. Clash! expresses the biggest idea in cultural psychology of the past three decades.”

Richard Shweder, PhD, author, Why Do Men Barbecue? Recipes for Cultural Psychology

We all see the daily battles around us – liberals versus conservatives, religious conservatives versus the more secular, and so on. This book explains why these battles are so fierce and the sides seem so unwilling to compromise.”

Ed Diener, PhD, coauthor, Happiness: Unlocking the Mysteries of Psychological Wealth
