Instant #1 New York Times BestsellerListed as a Times Self-Help Book of the YearDiscover the critical art of rethinking: how questioning your opinions can position you for excellence at work and wisdom in lifeIntelligence is usually seen as the ability to think and learn, but in a rapidly changing world, the most crucial skill may be the ability to rethink and unlearn. Recent global and political changes have forced many of us to re-evaluate our opinions and decisions. Yet we often still favour the comfort of conviction over the discomfort of doubt, and prefer opinions that make us feel good, instead of ideas that make us think hard.

Intelligence is no cure, and can even be a curse. The brighter we are, the blinder we can become to our own limitations. Adam Grant - Wharton's top-rated professor and #1 bestselling author - offers bold ideas and rigorous evidence to show how we can embrace the joy of being wrong, encourage others to rethink topics as wide-ranging as abortion and climate change, and build schools, workplaces, and communities of lifelong learners.

You'll learn how an international debate champion wins arguments, a Black musician persuades white supremacists to abandon hate, and how a vaccine whisperer convinces anti-vaxxers to immunize their children. Think Again is an invitation to let go of stale opinions and prize mental flexibility, humility, and curiosity over foolish consistency. If knowledge is power, knowing what you don't know is wisdom.
