Self Help

During his twenty years as a Navy officer and SEAL, Rich Diviney was intimately involved in a specialized SEAL selection process, which whittled a group of hundreds of extraordinary candidates down to a handful of the most elite performers. Diviney was often surprised by which candidates washed out and which succeeded. Some could have all the right skills and still fail, while others he might have initially dismissed would prove to be top performers. The seemingly objective criteria weren’t telling him what he most needed to know: Who would succeed in one of the world’s toughest military assignments?

It is similarly hard to predict success in the real world.

It happens often enough that underdog students accomplish exceptional achievements while highly skilled, motivated employees fail to meet expectations. Dark-horse companies pull away from the pack while dream teams flush with talent and capital go under. In working with and selecting top special operators for decades, Diviney saw that beneath obvious skills are hidden drivers of performance, surprising core attributes—including cunning, adaptability, courage, even narcissism—that determine how resilient or perseverant we are, how situationally aware and how conscientious. These attributes explain how we perform as individuals and as part of a team. The same methodology that Diviney used in the military can be applied by anyone in their personal and professional lives, and understanding these attributes can allow readers and their teams to perform optimally, at any time, in any situation.

Diviney defines the core attributes in fresh and practical ways and shares stories from the military, business, sports, relationships, and even parenting to show how understanding your own attributes and those of the people around you can create optimal performance in all areas of your 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. We think too much like preachers defending our sacred beliefs, prosecutors proving the other side wrong, and politicians campaigning for approval–and too little like scientists searching for truth. Intelligence is no cure, and it can even be a curse: being good at thinking can make us worse at rethinking. The brighter we are, the blinder to our own limitations we can become.

Organizational psychologist Adam Grant is an expert on opening other people’s minds–and our own. As Wharton’s top-rated professor and the bestselling author of Originals and Give and Take, he makes it one of his guiding principles 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, bring nuance to charged conversations, 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, a vaccine whisperer convinces concerned parents to immunize their children, and 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 over foolish consistency. If knowledge is power, knowing what we don’t know is wisdom.
