This book is about the world, and how to understand it. So why start with the circus? And why would I end a lecture by showing off in a sparkly top?

When I was a child my dream was to become a circus artist. My parents’ dream, though, was for me to get the good education they never had. So I ended up studying medicine.

Factfulness is … recognizing when we get negative news, and remembering that information about bad events is much more likely to reach us. When things are getting better we often don’t hear about them. This gives us a systematically too-negative impression of the world around us, which is very stressful.

To control the negativity instinct, expect bad news.

• Better and bad. Practice distinguishing between a level (e.g., bad) and a direction of change (e.g., better). Convince yourself that things can be both better and bad.

• Good news is not news. Good news is almost never reported. So news is almost always bad. When you see bad news, as

• Gradual improvement is not news. When a trend is gradually improving, with periodic dips, you are more likely to notice the dips than the overall improvement.

• More news does not equal more suffering. More bad news is sometimes due to better surveillance of suffering, not a worsening world.

• Beware of rosy pasts. People often glorify their early experiences, and nations often glorify their histories.

Factfulness is … recognizing that a single perspective can limit your imagination, and remembering that it is better to look at problems from many angles to get a more accurate understanding and find practical solutions.

To control the single perspective instinct, get a toolbox, not a hammer.

• Test your ideas. Don’t only collect examples that show how excellent your favorite ideas are. Have people who disagree with you test your ideas and find their weaknesses.

It’s not the numbers that are interesting. It’s what they tell us about the lives behind the numbers

I’m talking about that irresistible temptation we have to divide all kinds of things into two distinct and often conflicting groups, with an imagined gap—a huge chasm of injustice—in between.
