Think Again: The Power of Knowing What You Don't Know by Adam Grant (best e book reader for android txt) 📗

avoid penalties, which made it difficult for anyone to diagnose the root causes and prevent future problems. They kept repeating the same mistakes.

Since then, research on psychological safety has flourished. When I was involved in a study at Google to identify the factors that distinguish teams with high performance and well-being, the most important differentiator wasn’t who was on the team or even how meaningful their work was. What mattered most was psychological safety.

Over the past few years, psychological safety has become a buzzword in many workplaces. Although leaders might understand its significance, they often misunderstand exactly what it is and how to create it. Edmondson is quick to point out that psychological safety is not a matter of relaxing standards, making people comfortable, being nice and agreeable, or giving unconditional praise. It’s fostering a climate of respect, trust, and openness in which people can raise concerns and suggestions without fear of reprisal. It’s the foundation of a learning culture.

In performance cultures, the emphasis on results often undermines psychological safety. When we see people get punished for failures and mistakes, we become worried about proving our competence and protecting our careers. We learn to engage in self-limiting behavior, biting our tongues rather than voicing questions and concerns. Sometimes that’s due to power distance: we’re afraid of challenging the big boss at the top. The pressure to conform to authority is real, and those who dare to deviate run the risk of backlash. In performance cultures, we also censor ourselves in the presence of experts who seem to know all the answers—especially if we lack confidence in our own expertise.

A lack of psychological safety was a persistent problem at NASA. Before the Challenger launch, some engineers did raise red flags but were silenced by managers; others were ignored and ended up silencing themselves. After the Columbia launch, an engineer asked for clearer photographs to inspect the damage to the wing, but managers didn’t supply them. In a critical meeting to evaluate the condition of the shuttle after takeoff, the engineer didn’t speak up.

About a month before that Columbia launch, Ellen Ochoa became the deputy director of flight crew operations. In 1993, Ellen had made history by becoming the first Latina in space. Now, the first flight she supported in a management role had ended in tragedy. After breaking the news to the space station crew and consoling the family members of the fallen astronauts, she was determined to figure out how she could personally help to prevent this kind of disaster from ever happening again.

Ellen recognized that at NASA, the performance culture was eroding psychological safety. “People pride themselves on their engineering expertise and excellence,” she told me. “They fear their expertise will be questioned in a way that’s embarrassing to them. It’s that basic fear of looking like a fool, asking questions that people just dismiss, or being told you don’t know what you’re talking about.” To combat that problem and nudge the culture toward learning, she started carrying a 3 × 5 note card in her pocket with questions to ask about every launch and important operational decision. Her list included:

What leads you to that assumption? Why do you think it is correct? What might happen if it’s wrong?

What are the uncertainties in your analysis?

I understand the advantages of your recommendation. What are the disadvantages?

A decade later, though, the same lessons about rethinking would have to be relearned in the context of spacewalk suits. As flight controllers first became aware of the droplets of water in Luca Parmitano’s helmet, they made two faulty assumptions: the cause was the drink bag, and the effect was inconsequential. It wasn’t until the second spacewalk, when Luca was in actual danger, that they started to question whether those assumptions were wrong.

When engineer Chris Hansen took over as the manager of the extravehicular activity office, he inaugurated a norm of posing questions like Ellen’s: “All anybody would’ve had to ask is, ‘How do you know the drink bag leaked?’ The answer would’ve been, ‘Because somebody told us.’ That response would’ve set off red flags. It would’ve taken ten minutes to check, but nobody asked. It was the same for Columbia. Boeing came in and said, ‘This foam, we think we know what it did.’ If somebody had asked how they knew, nobody could’ve answered that question.”

How do you know? It’s a question we need to ask more often, both of ourselves and of others. The power lies in its frankness. It’s nonjudgmental—a straightforward expression of doubt and curiosity that doesn’t put people on the defensive. Ellen Ochoa wasn’t afraid to ask that question, but she was an astronaut with a doctorate in engineering, serving in a senior leadership role. For too many people in too many workplaces, the question feels like a bridge too far. Creating psychological safety is easier said than done, so I set out to learn about how leaders can establish it.

SAFE AT HOME GATES

When I first arrived at the Gates Foundation, people were whispering about the annual strategy reviews. It’s the time when program teams across the foundation meet with the cochairs—Bill and Melinda Gates—and the CEO to give progress reports on execution and collect feedback. Although the foundation employs some of the world’s leading experts in areas ranging from eradicating disease to promoting educational equity, these experts are often intimidated by Bill’s knowledge base, which seems impossibly broad and deep. What if he spots a fatal flaw in my work? Will it be the end of my career here?

A few years ago, leaders at the Gates Foundation reached out to see if I could help them build psychological safety. They were worried that the pressure to present airtight analyses was discouraging people from taking risks. They often stuck to tried-and-true strategies that would make incremental progress rather than daring to undertake bold experiments that might make a bigger dent in some of the world’s most vexing problems.

The existing evidence on creating psychological safety gave us
