A select few countries are on Level 1 and Level 4. He says that the majority of the countries in the world are on Level 2 or Level 3. Instead, he offers a four category model based on income per person (adjusted for price differences): He shows that today most countries are 'developed' and the others are not how developing countries were when the term became popular.

Rosling criticizes the notion of dividing the world into the ' developed world' and the ' developing world' by calling it an outdated view. (Left to right) Anna Rosling Rönnlund, Hans Rosling, and Ola Rosling discuss their book Factfulness in 2016.

īill Gates highlighted the book as one of his suggested five books worth reading for summer 2018, offering to purchase a copy for any 2018 college graduate upon request. Rosling recommends thinking about the world as divided into four levels based on income brackets (rather than the prototypical developed/developing framework) and suggests ten instincts that prevent us from seeing real progress in the world. He demonstrates that his test subjects believe the world is poorer, less healthy, and more dangerous than it actually is, attributing this not to random chance but to misinformation. In the book, Rosling suggests that the vast majority of people are wrong about the state of the world. The book was published posthumously a year after Hans Rosling died from pancreatic cancer. Factfulness: Ten Reasons We're Wrong About the World – and Why Things Are Better Than You Think is a 2018 book by Swedish physician, professor of international health at Karolinska Institute and statistician Hans Rosling with his son Ola Rosling and daughter-in-law Anna Rosling Rönnlund.
