Factfulness: Ten Reasons We're Wrong About the World—and Why Things Are Better Than You Think

by Hans Rosling

Every group of people I ask thinks the world is more frightening, more violent, and more hopeless—in short, more dramatic—than it really is.

I realized the problem couldn’t simply be that people lacked the knowledge, because that would give randomly incorrect answers—chimpanzee answers—rather than worse-than-random, worse-than-chimpanzee, systematically wrong answers. Only actively wrong “knowledge” can make us score so badly.

Think about the world. War, violence, natural disasters, man-made disasters, corruption. Things are bad, and it feels like they are getting worse, right? The rich are getting richer and the poor are getting poorer; and the number of poor just keeps increasing; and we will soon run out of resources unless we do something drastic. At least that’s the picture that most Westerners see in the media and carry around in their heads. I call it the overdramatic worldview. It’s stressful and misleading. In fact, the vast majority of the world’s population lives somewhere in the middle of the income scale. Perhaps they are not what we think of as middle class, but they are not living in extreme poverty. Their girls go to school, their children get vaccinated, they live in two-child families, and they want to go abroad on holiday, not as refugees. Step-by-step, year-by-year, the world is improving. Not on every single measure every single year, but as a rule. Though the world faces huge challenges, we have made tremendous progress. This is the fact-based worldview.

We love to dichotomize. Good versus bad. Heroes versus villains. My country versus the rest. Dividing the world into two distinct sides is simple and intuitive, and also dramatic because it implies conflict, and we do it without thinking, all the time.

Factfulness is … recognizing when a story talks about a gap, and remembering that this paints a picture of two separate groups, with a gap in between. The reality is often not polarized at all. Usually the majority is right there in the middle, where the gap is supposed to be. To control the gap instinct, look for the majority. • Beware comparisons of averages. If you could check the spreads you would probably find they overlap. There is probably no gap at all. • Beware comparisons of extremes. In all groups, of countries or people, there are some at the top and some at the bottom. The difference is sometimes extremely unfair. But even then the majority is usually somewhere in between, right where the gap is supposed to be. • The view from up here. Remember, looking down from above distorts the view. Everything else looks equally short, but it’s not.

The Chinese harvest in 1960 was smaller than planned because of a bad season combined with poor governmental advice about how to grow crops more effectively. The local governments didn’t want to show bad results, so they took all the food and sent it to the central government. There was no food left. One year later the shocked inspectors were delivering eyewitness reports of cannibalism and dead bodies along roads. The government denied that its central planning had failed, and the catastrophe was kept secret by the Chinese government for 36 years. It wasn’t described in English to the outside world until 1996. (Think about it. Could any government keep the death of 15 million people a global secret today?)

The goal of higher income is not just bigger piles of money. The goal of longer lives is not just extra time. The ultimate goal is to have the freedom to do what we want. Me, I love the circus, and playing computer games with my grandchildren, and zapping through TV channels. Culture and freedom, the goals of development, can be hard to measure, but guitars per capita is a good proxy. And boy, has that improved. With beautiful statistics like these, how can anyone say the world is getting worse?

Dental health, for example, gets worse as people move from Level 1 to Level 2, then improves again on Level 4. This is because people start to eat sweets as soon as they can afford them, but their governments cannot afford to prioritize preventive public education about tooth decay until Level 3. So poor teeth are an indicator of relative poverty on Level 4, but on Level 1 they may indicate the opposite.

Most people’s incomes grow much slower than bacteria, unfortunately. Still, even if your income increases by only 2 percent a year, after 35 years it will have doubled. And then, if you maintain 2 percent growth, in another 35 years it will have doubled again. Over 200 years—if you lived that long—it would double six times, which is exactly what we saw in Sweden’s bubble trail in the last chapter, and which is typically the slow and steady way countries have moved from Level 1 to Level 4.

I didn’t see what I wanted to see. I saw what I was afraid of seeing. Critical thinking is always difficult, but it’s almost impossible when we are scared. There’s no room for facts when our minds are occupied by fear.

For the first time in world history, data exists for almost every aspect of global development. And yet, because of our dramatic instincts and the way the media must tap into them to grab our attention, we continue to have an overdramatic worldview. Of all our dramatic instincts, it seems to be the fear instinct that most strongly influences what information gets selected by news producers and presented to us consumers.

Factfulness is … recognizing when frightening things get our attention, and remembering that these are not necessarily the most risky. Our natural fears of violence, captivity, and contamination make us systematically overestimate these risks. To control the fear instinct, calculate the risks. • The scary world: fear vs. reality. The world seems scarier than it is because what you hear about it has been selected—by your own attention filter or by the media—precisely because it is scary. • Risk = danger × exposure. The risk something poses to you depends not on how scared it makes you feel, but on a combination of two things. How dangerous is it? And how much are you exposed to it? • Get calm before you carry on. When you are afraid, you see the world differently. Make as few decisions as possible until the panic has subsided.

To control the size instinct, get things in proportion. • Compare. Big numbers always look big. Single numbers on their own are misleading and should make you suspicious. Always look for comparisons. Ideally, divide by something. • 80/20. Have you been given a long list? Look for the few largest items and deal with those first. They are quite likely more important than all the others put together. • Divide. Amounts and rates can tell very different stories. Rates are more meaningful, especially when comparing between different-sized groups. In particular, look for rates per person when comparing between countries or regions.

When many people become aware of a problematic generalization it is called a stereotype. Most commonly, people talk about race and gender stereotyping. These cause many very important problems, but they are not the only problems caused by wrong generalizations. Wrong generalizations are mind-blockers for all kinds of understanding.

It will be helpful to you if you always assume your categories are misleading. Here are five powerful ways to keep questioning your favorite categories: look for differences within and similarities across groups; beware of “the majority”; beware of exceptional examples; assume you are not “normal”; and beware of generalizing from one group to another.

Assume You Are Not “Normal” and Other People Are Not Idiots

Even changes that seem small and slow add up over time: 1 percent growth each year seems slow but it adds up to a doubling in 70 years; 2 percent growth each year means doubling in 35 years; 3 percent growth each year means doubling in 24 years.

The Single Perspective Instinct We find simple ideas very attractive. We enjoy that moment of insight, we enjoy feeling we really understand or know something. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple. All problems have a single cause—something we must always be completely against. Or all problems have a single solution—something we must always be for. Everything is simple. There’s just one small issue. We completely misunderstand the world.

Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you like to understand reality. Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, see people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. I have been wrong about the world so many times.

I love experts, but they have their limitations. First, and most obviously, experts are experts only within their own field. That can be difficult for experts (and we are all experts in something) to admit. We like to feel knowledgeable and we like to feel useful. We like to feel that our special skills make us generally better. But … Highly numerate people (like the super-brainy audience at the Amazing Meeting, an annual gathering of people who love scientific reasoning) score just as badly on our fact questions as everyone else. Highly educated people (like the readers of Nature, one of the world’s finest scientific journals) score just as badly on our fact questions as everyone else, and often even worse. People with extraordinary expertise in one field score just as badly on our fact questions as everyone else. I had the honor of attending the 64th Lindau Nobel Laureate Meeting, and addressing a large group of talented young scientists and Nobel laureates in physiology and medicine. They were the acknowledged intellectual elite of their field, and yet on the question about child vaccination they scored worse than any public polls: 8 percent got the answer right. (After this I never take it for granted that brilliant experts will know anything about closely related fields outside their specializations.)

Anyone who claims that democracy is a necessity for economic growth and health improvements will risk getting contradicted by reality. It’s better to argue for democracy as a goal in itself instead of as a superior means to other goals we like. There is no single measure—not GDP per capita, not child mortality (as in Cuba), not individual freedom (as in the United States), not even democracy—whose improvement will guarantee improvements in all the others. There is no single indicator through which we can measure the progress of a nation. Reality is just more complicated than that.

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. • Limited expertise. Don’t claim expertise beyond your field: be humble about what you don’t know. Be aware too of the limits of the expertise of others. • Hammers and nails. If you are good with a tool, you may want to use it too often. If you have analyzed a problem in depth, you can end up exaggerating the importance of that problem or of your solution. Remember that no one tool is good for everything. If your favorite idea is a hammer, look for colleagues with screwdrivers, wrenches, and tape measures. Be open to ideas from other fields. • Numbers, but not only numbers. The world cannot be understood without numbers, and it cannot be understood with numbers alone. Love numbers for what they tell you about real lives. • Beware of simple ideas and simple solutions. History is full of visionaries who used simple utopian visions to justify terrible actions. Welcome complexity. Combine ideas. Compromise. Solve problems on a case-by-case basis.

To understand most of the world’s significant problems we have to look beyond a guilty individual and to the system.

To control the blame instinct, resist finding a scapegoat. • Look for causes, not villains. When something goes wrong don’t look for an individual or a group to blame. Accept that bad things can happen without anyone intending them to. Instead spend your energy on understanding the multiple interacting causes, or system, that created the situation. • Look for systems, not heroes. When someone claims to have caused something good, ask whether the outcome might have happened anyway, even if that individual had done nothing. Give the system some credit.

Data must be used to tell the truth, not to call to action, no matter how noble the intentions.

Factfulness is … recognizing when a decision feels urgent and remembering that it rarely is. To control the urgency instinct, take small steps. • Take a breath. When your urgency instinct is triggered, your other instincts kick in and your analysis shuts down. Ask for more time and more information. It’s rarely now or never and it’s rarely either/or. • Insist on the data. If something is urgent and important, it should be measured. Beware of data that is relevant but inaccurate, or accurate but irrelevant. Only relevant and accurate data is useful. • Beware of fortune-tellers. Any prediction about the future is uncertain. Be wary of predictions that fail to acknowledge that. Insist on a full range of scenarios, never just the best or worst case. Ask how often such predictions have been right before. • Be wary of drastic action. Ask what the side effects will be. Ask how the idea has been tested. Step-by-step practical improvements, and evaluation of their impact, are less dramatic but usually more effective.

They would protect the next generation from a lot of ignorance. • We should be teaching our children that there are countries on all different levels of health and income and that most are in the middle. • We should be teaching them about their own country’s socioeconomic position in relation to the rest of the world, and how that is changing. • We should be teaching them how their own country progressed through the income levels to get to where it is now, and how to use that knowledge to understand what life is like in other countries today. • We should be teaching them that people are moving up the income levels and most things are improving for them. • We should be teaching them what life was really like in the past so that they do not mistakenly think that no progress has been made. • We should be teaching them how to hold the two ideas at the same time: that bad things are going on in the world, but that many things are getting better. • We should be teaching them that cultural and religious stereotypes are useless for understanding the world. • We should be teaching them how to consume the news and spot the drama without becoming stressed or hopeless. • We should be teaching them the common ways that people will try to trick them with numbers. • We should be teaching them that the world will keep changing and they will have to update their knowledge and worldview throughout their lives.

Being humble, here, means being aware of how difficult your instincts can make it to get the facts right. It means being realistic about the extent of your knowledge. It means being happy to say “I don’t know.” It also means, when you do have an opinion, being prepared to change it when you discover new facts. It is quite relaxing being humble, because it means you can stop feeling pressured to have a view about everything, and stop feeling you must be ready to defend your views all the time.

Being curious means being open to new information and actively seeking it out. It means embracing facts that don’t fit your worldview and trying to understand their implications. It means letting your mistakes trigger curiosity instead of embarrassment. “How on earth could I be so wrong about that fact? What can I learn from that mistake? Those people are not stupid, so why are they using that solution?” It is quite exciting being curious, because it means you are always discovering something interesting.
