Book Review – Factfulness

The world today seems like a scary place. Many things or incidences are being shown as negative. But are things as bad as they seem?

Swedish statistician Hans Rosling in his 2018 book, Factfulness, took a step back to analyze trends and data to see whether our lives are getting worse or better, and show that on larger canvas perhaps things are better.

Factfulness is about understanding how our instincts program us to exaggerate situations and distort our perception of reality in ways that further exacerbate problems and how we react to them. In his book, Rosling outlines ten of these fundamental instincts and how to combat them to cultivate shift towards a perception based in the fact that will ultimately alter the way we think, feel, and behave as a result. 

Here is a summary of major 10 key insights and lessons for building a more “factful” perspective:

1. The Gap Instinct 

Summary: The tendency to divide things into distinct and often opposing groups and project some sort of gap between them (e.g. us and them).

Key Takeaways:

  • More than 85% of the modern world falls into what we would call in the past, the “developed” world, with most of the remaining 15% in between “developed” and “developing.” As few as 13 countries (6% of the world’s population) qualify as “developing” countries. 
  • In addition to this, low-income countries are significantly more developed than most people think, with vastly fewer people still living in them. This means the perception of a massively divided world in which the majority remains relatively poor and deprived is a misconception. 


  • The world is better understood by imagining data distributions on a bell-curve rather than as a series of opposing polarities – the majority (and accurate perception) usually exists in the middle, not as warring opposites. Polarizing our view of the world can foster an “us versus them” mentality that spills into our actions and imagines a separation “them” and “us” that in fact, does not truly exist.

2. The Negativity Instinct

Summary: The tendency to emphasize the negatives over positives (or in evolutionary terms, threats versus opportunities – e.g. believing that things are getting worse when they may actually be getting better).

Key Takeaways:

  • People’s attention naturally gravitates towards negatives over positives. Evolutionists would argue that this prioritization is a biological protective mechanism to help us recognize danger. However, this instinct can also bias us towards a more negative perception of many things than is actually true. 
  • Mass-media can often fuel negative perception since it rewards and emphasizes that which will garner the most attention, which is more frequently negative than positive. Good news and gradual improvement don’t make for great topics, and often negative perception is owed more to surveillance of suffering than a worsening world. 


  • Recognize that the media machine feeding us news prioritizes negativity by nature, but that doesn’t mean the nature of things is negative. Like with the first instinct above, the truth is most often found somewhere in the middle. 

3. The Straight Line Instinct

Summary: The tendency to believe that things will continue as they have before.

Key Takeaways:

  • We know that things change (often permanently) over time, yet we so often fallaciously believe that one aspect or another of life will remain constant. 
  • We often seem to believe that the earth’s population is somewhat static and stable, but data reveals that the world’s population is actively growing and there is little indication of that slowing. This raises questions about how to manage natural resources and the potential implications for future generations.


  • Acknowledge that many things will change over time and pay attention to data that may protect you from falsely believing that some aspect of your life will continue as it has before. 

4. The Fear Instinct

Summary: The tendency to pay more attention to “frightening” things.

Key Takeaways:

  • Much like our instinct to gravitate towards negativity and our brain’s programming to identify threats, we tend to notice things that scare us. However, this same protective instinct often leads us to exaggerate our negative perceptions, and fear left unchecked can cloud our judgement and decision-making.
  • The world can seem scarier and more dangerous because what you see and hear is selected, either by your own internal filters or information outlets like the news and media for the very fact that it is scary.


  • Risks should be calculated, not avoided. There is no way to eliminate risk without negating opportunity. In the same way, if we let our fear steer us we will miss many positive due to miscalculating situations.  
  • Unbalanced, fear can lead to panic, and panic only increases risk.

5. The Size Instinct 

Summary: The tendency to perceive things out of proportion (especially when isolated numbers seem impressive).

Key Takeaways:

  • We tend to misperceive scale and volume often when we base too much of our conclusions on small sample sizes and solitary bits of data. Fragmented evidence can easily lead to an inaccurate sense of proportion, which can, in turn, produce misdiagnoses of problems and misallocated resources and solutions.
  • Numbers, while they seem straightforward and factual, can be woven to tell many stories. It’s critical to examine data in context and use numbers like pieces of a puzzle to form a complete picture.


  • There are two critical tools for properly contextualizing your perception: Comparing and Dividing. Compare your data and numbers with different numbers, data, and sources to gain a more accurate approximation. Dividing allows you to examine rates and ratios, and rates are often more meaningful, especially when comparing groups of different size or scale. 

6. The Generalization Instinct

Summary: The tendency to generalize by categories.

Key Takeaways:

  • Generalizing makes us vulnerable to missing details and differences. Similar to the Gap Instinct, we tend to divide things into binary groups to more easily understand them, but this can also easily blind us to diversity inside and between individual groups.
  • Beware of simple and exaggerated generalizations.


  • Cultivate a habit of questioning your categories and noticing differences that can provide data for a new and refined understanding of things and groups. 

7. The Destiny Instinct

Summary: The tendency to believe that seemingly inborn and past characteristics determine the “destiny” of people, things, groups, institutions, or cultures and that they will remain the same.

Key Takeaways:

  • Small changes compound with time and trajectory. A closer look across history at changes in almost any area will show that things change radically and often given enough time. 
  • Change at the micro-level of an individual can seem apparent, but a change in groups often takes more time. It is easy to fail to recognize change around us when it’s slow, but valuable to remember that small change adds up to a significant difference over time. 


  • If things seem like they’re not changing fast enough, the same rules from the Size Instinct apply: Comparing and divide
  • Update your knowledge – Some information changes more quickly than others. Technologies, countries, societies, cultures, and religion are constantly changing and it’s important to refresh your perspective with new knowledge.

8. The Single Perspective 

Summary: The tendency to prefer simple explanations and solutions and miss differing perspectives, angles and complexities.

Key Takeaways:

  • “Being always in favour 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 favourite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about the new information that does not fit, and information from other fields.


  • Factfulness involves recognizing that we cannot develop the best perspective without accounting for others. Our ideas should be tested and refined but different angles, data, and opinions. 

9. The Blame Instinct

Summary: The tendency to seek simple and clear reasons for why a bad thing occurs.

Key Takeaways:

  • People tend to look for guilty parties to blame for problems, but problems and their causes are often more complex than we want to realize. People are often more preoccupied with rationalizing someone’s fault and pointing fingers than truly analyzing the problem and developing a real solution.


  • Look for causes, not villains. Recognize that bad things occur always and that your energy is best directed towards solving the deeper, intricate and interacting reasons underneath the surface.
  • Look for systems, not heroes – When something consistently works well, it is often because there is a system supporting and facilitating individuals more than any one person’s heroics. Ask just how much influence the individual can or might have had given the systems that support the outcome. 

10. The Urgency Instinct

Summary: The tendency to take immediate actions in response to perceived danger or threats, and in doing so, amplify our other instincts.

Key Takeaways:

  • Taking immediate action in the face of oncoming physical danger is a helpful instinct that has enabled us to survive. Yet, the problems and threats of the modern world are most often slower and more complex than an attacking lion or angry enemy. As such, abstract problems require more complex solutions, and reacting with too much urgency and force can lead to bad decisions and outcomes. 


  • Urgency can be helpful, but it can also amplify all of our other biases, instincts, and reactions and lead us to make mistakes in panic. When urgency clouds your thinking, take a deep breath, examine the data, think analytically, and beware of predictions that fail to account for uncertainty and complexity.

Hope, this will help you to review the situations and realign them in a “factful” manner.
