Factfulness: Ten Reasons We're Wrong About the World – and Why Things Are Better Than You Think (39 page)

Mattias Lindgren for compiling most of the Gapminder historic time series for the economy and demography. All my students and doctoral students, from whom I learned so much, all the teachers and students who welcomed us to their schools to help us test our materials, all the amazing consultants around the world who have helped us, Jimmy Wales and the voluntary editors on Wikipedia, and all the Dollar Street families and photographers.

The previous and current board members of the Gapminder Foundation for their wise and stable support: Hans Wigzell, Christer Gunnarsson, Bo Sundgren, Gun-Britt Andersson, and Helena Nordenstedt (who also helped with fact-checking). And our amazing Gapminder team, Angie Skazka, Gabriela Sá, Jasper Heeffer, Klara Elzvik, Mikael Arevius, and Olof Gränström, headed by Fernanda Drumond, who tirelessly continued to develop Gapminder’s free teaching materials while we finished this book. And who also gave invaluable input to the manuscript!

And finally, our wonderful friends and families, for being patient with us and for helping us throughout the process. You know who you are. Without you this book would not have been possible. Thank you.

In 2017, the Gapminder Test launched. It consists of 13 questions, all with an A, B, C alternative. In 2017, Gapminder worked with Ipsos MORI and Novus to test 12,000 people in 14 countries. Their polls were conducted with online panels weighted to be representative of the adult populations. The test was conducted in Australia, Belgium, Canada, Finland, France, Germany, Hungary, Japan, Norway, South Korea, Spain, Sweden, the United Kingdom, and the United States. The 13 fact questions are freely available in multiple languages at
