'This book is my last battle in my life-long mission to fight devastating ignorance, and my final attempt at making an impact on the world. It has been my daily inspiration and joy. In my previous battles I armed myself with huge data sets, beautiful software, an energetic lecturing style and a Swedish bayonet for sword swallowing. It wasn't enough. But I hope that this book will be.'When you ask people simple questions about global trends, they systematically get the answers wrong. How many young women go to school? What's the average life expectancy across the world? What will the global population will be in 2050? Do the majority of people live in rich or poor countries? In Factfulness, Hans Rosling and his two lifelong collaborators, Ola Rosling and Anna Rosling-Ronnlund, show why this happens. Based on a lifetime's work promoting a fact-based worldview, they reveal the ten dramatic instincts, and the key preconceptions, that lead to us consistently misunderstanding how the world really works. Inspiring and revelatory, Factfulness is a book of stories by a late legend, for anyone who wants to really understand the world.
