Think Again: The Power of Knowing What You Don't Know by Adam Grant (sad books to read txt) 📕

The other is desirability bias: seeing what we want to see. These biases don’t just prevent us from applying our intelligence. They can actually contort our intelligence into a weapon against the truth. We find reasons to preach our faith more deeply, prosecute our case more passionately, and ride the tidal wave of our political party. The tragedy is that we’re usually unaware of the resulting flaws in our thinking.

My favorite bias is the “I’m not biased” bias, in which people believe they’re more objective than others. It turns out that smart people are more likely to fall into this trap. The brighter you are, the harder it can be to see your own limitations. Being good at thinking can make you worse at rethinking.

When we’re in scientist mode, we refuse to let our ideas become ideologies. We don’t start with answers or solutions; we lead with questions and puzzles. We don’t preach from intuition; we teach from evidence. We don’t just have healthy skepticism about other people’s arguments; we dare to disagree with our own arguments.

Thinking like a scientist involves more than just reacting with an open mind. It means being actively open-minded. It requires searching for reasons why we might be wrong—not for reasons why we must be right—and revising our views based on what we learn.

That rarely happens in the other mental modes. In preacher mode, changing our minds is a mark of moral weakness; in scientist mode, it’s a sign of intellectual integrity. In prosecutor mode, allowing ourselves to be persuaded is admitting defeat; in scientist mode, it’s a step toward the truth. In politician mode, we flip-flop in response to carrots and sticks; in scientist mode, we shift in the face of sharper logic and stronger data.

I’ve done my best to write this book in scientist mode.* I’m a teacher, not a preacher. I can’t stand politics, and I hope a decade as a tenured professor has cured me of whatever temptation I once felt to appease my audience. Although I’ve spent more than my share of time in prosecutor mode, I’ve decided that in a courtroom I’d rather be the judge. I don’t expect you to agree with everything I think. My hope is that you’ll be intrigued by how I think—and that the studies, stories, and ideas covered here will lead you to do some rethinking of your own. After all, the purpose of learning isn’t to affirm our beliefs; it’s to evolve our beliefs.

One of my beliefs is that we shouldn’t be open-minded in every circumstance. There are situations where it might make sense to preach, prosecute, and politick. That said, I think most of us would benefit from being more open more of the time, because it’s in scientist mode that we gain mental agility.

When psychologist Mihaly Csikszentmihalyi studied eminent scientists like Linus Pauling and Jonas Salk, he concluded that what differentiated them from their peers was their cognitive flexibility, their willingness “to move from one extreme to the other as the occasion requires.” The same pattern held for great artists, and in an independent study of highly creative architects.

We can even see it in the Oval Office. Experts assessed American presidents on a long list of personality traits and compared them to rankings by independent historians and political scientists. Only one trait consistently predicted presidential greatness after controlling for factors like years in office, wars, and scandals. It wasn’t whether presidents were ambitious or forceful, friendly or Machiavellian; it wasn’t whether they were attractive, witty, poised, or polished.

What set great presidents apart was their intellectual curiosity and openness. They read widely and were as eager to learn about developments in biology, philosophy, architecture, and music as in domestic and foreign affairs. They were interested in hearing new views and revising their old ones. They saw many of their policies as experiments to run, not points to score. Although they might have been politicians by profession, they often solved problems like scientists.

DON’T STOP UNBELIEVING

As I’ve studied the process of rethinking, I’ve found that it often unfolds in a cycle. It starts with intellectual humility—knowing what we don’t know. We should all be able to make a long list of areas where we’re ignorant. Mine include art, financial markets, fashion, chemistry, food, why British accents turn American in songs, and why it’s impossible to tickle yourself. Recognizing our shortcomings opens the door to doubt. As we question our current understanding, we become curious about what information we’re missing. That search leads us to new discoveries, which in turn maintain our humility by reinforcing how much we still have to learn. If knowledge is power, knowing what we don’t know is wisdom.

Scientific thinking favors humility over pride, doubt over certainty, curiosity over closure. When we shift out of scientist mode, the rethinking cycle breaks down, giving way to an overconfidence cycle. If we’re preaching, we can’t see gaps in our knowledge: we believe we’ve already found the truth. Pride breeds conviction rather than doubt, which makes us prosecutors: we might be laser-focused on changing other people’s minds, but ours is set in stone. That launches us into confirmation bias and desirability bias. We become politicians, ignoring or dismissing whatever doesn’t win the favor of our constituents—our parents, our bosses, or the high school classmates we’re still trying to impress. We become so busy putting on a show that the truth gets relegated to a backstage seat, and the resulting validation can make us arrogant. We fall victim to the fat-cat syndrome, resting on our laurels instead of pressure-testing our beliefs.

In the case of the BlackBerry, Mike Lazaridis was trapped in an overconfidence cycle. Taking pride in his successful invention gave him too much conviction. Nowhere was that clearer than in his preference for the keyboard over a touchscreen. It was a BlackBerry virtue he loved to preach—and an Apple vice he was quick to prosecute. As his company’s stock fell, Mike got caught up in confirmation bias and
