"Brilliant... guaranteed to make you rethink your opinions and your most important decisions." –Nobel Prize winner Daniel Kahneman

“THIS. This is the right book for right now. Yes, learning requires focus. But, unlearning and relearning requires much more—it requires choosing courage over comfort. In Think Again, Adam Grant weaves together research and storytelling to help us build the intellectual and emotional muscle we need to stay curious enough about the world to actually change it. I’ve never felt so hopeful about what I don’t know.”

“Adam Grant makes a captivating argument that if we have the humility and curiosity to reconsider our beliefs, we can always reinvent ourselves. Think Again helped me learn about how great thinkers and achievers don’t let expertise or experience stand in the way of being perpetual students.”

I loved this one!”

Malcolm Gladwell

#1 New York Times bestselling author of Outliers and host of Revisionist History

“In a world of aggressive certitude, Adam Grant’s latest book is a refreshing mandate for humble open-mindedness. Think Again offers a particularly powerful case for rethinking what we already know… that is not just a useful lesson; it could be a vital one.”

The Financial Times

“Grant, an organizational psychologist, coaches readers on how to better understand their unexamined — and unchallenged — beliefs. Think Again delivers smart advice on unlearning assumptions and opening ourselves up to curiosity and humility.”

The Washington Post

“I highly recommend Think Again. Adam is one the most revered experts in what makes organizations and people successful and he loudly and clearly tells you what is most important… Adam’s book… will radically improve your life.”

Ray Dalio

Founder of Bridgewater Associates and #1 New York Times bestselling author of Principles

Think Again is a must-read for anyone who wants to create a culture of learning and exploration, whether at home, at work, or at school. With warmth and humor, Adam Grant distills complex research into a compelling case for why each of us should continually question old assumptions and embrace new ideas and perspectives. In an increasingly divided world, the lessons in this book are more important than ever.”

The bestselling author of Give and Take and Originals examines the critical art of rethinking: learning to question your opinions and open other people’s minds, which can position you for excellence at work and wisdom in life

Intelligence is usually seen as the ability to think and learn, but in a rapidly changing world, there’s another set of cognitive skills that might matter more: the ability to rethink and unlearn. In our daily lives, too many of us favor the comfort of conviction over the discomfort of doubt. We listen to opinions that make us feel good, instead of ideas that make us think hard. We see disagreement as a threat to our egos, rather than an opportunity to learn. We surround ourselves with people who agree with our conclusions, when we should be gravitating toward those who challenge our thought process. The result is that our beliefs get brittle long before our bones. Intelligence is no cure, and it can even be a curse: there’s evidence that being good at thinking can make us worse at rethinking. The brighter we are, the blinder to our own limitations we can become.

As an organizational psychologist, Adam Grant is an expert on opening other people’s minds–and our own. As Wharton’s top-rated professor and the #1 New York Times bestselling author of Originals and Give and Take, one of his guiding principles is to argue like he’s right but listen like he’s wrong. With bold ideas and rigorous evidence, he investigates how we can embrace the joy of being wrong, harness the surprising advantages of impostor syndrome, bring nuance to charged conversations, and build schools, workplaces, and communities of lifelong learners. You’ll learn how an international debate champion wins arguments, how a Black musician persuades white supremacists to abandon hate, how a vaccine whisperer convinces concerned parents to immunize their children, and how Adam has coaxed Yankees fans to root for the Red Sox. Think Again reveals that we don’t have to believe everything we think or internalize everything we feel. It’s an invitation to let go of views that are no longer serving us well and prize mental flexibility, humility, and curiosity over foolish consistency. If knowledge is power, knowing what we don’t know is wisdom.
