“A hopeful book about the potential for human progress when we work off facts rather than our inherent biases.”
– Barack Obama

Asking big questions about the world is easy. How many people live below the poverty line? How many girls go to school? Why is the global population increasing? How much money do you need to live a happy life?

But answering them ‘factfully’ is hard. So hard in fact, that because of our internal biases we get them wrong more often than not.

In their new book Factfulness, the late, great Professor Hans Rosling, together with his son and daughter-in-law Ola Rosling and Anna Rosling Rönnlund offer a radical new explanation of why we so often make these mistakes. Together Anna and Ola will reveal the 10 instincts that distort our perspective and outline why when we think about the world, we need to stop considering our feelings and start considering the facts.

This event is presented in partnership with Auckland Writers Festival, Byron Writers Festival and State Library of Queensland.

Anna Rosling Rönnlund

Anna Rosling Rönnlund

Anna Rosling Rönnlund holds a Master’s Degree in Sociology and a Bachelor’s Degree in Photography.

She founded the Gapminder Foundation in 2005 with Hans Rosling and Ola Rosling to fight devastating ignorance with a fact-based worldview everyone can understand. She designed the user-interface of the famous animating bubble-chart tool called Trendalyzer, used by millions of students across the world, to understand global development trends. The tool was acquired by Google where she worked as a Senior Usability Designer from 2007 to 2010.

At Google, Anna improved search results for public data, developed data exploration tools for public data and made a bubble tool gadget (Motion Chart) in Google Spreadsheets.

In 2010 Anna came back to Gapminder to develop new free teaching material. Anna is now Vice President and Head of Design & User Experience at Gapminder. She also sits in the Gapminder Board. Anna founded Dollar Street, the biggest systematic image bank with representative home documentations based on data. At the moment it has almost 30,000 photos and 10,000 video clips.

Ola Rosling

Ola Rosling

Ola Rosling is President & Co-Founder of Gapminder Foundation, which he founded together with his wife and his father.

Since 1999, Ola lead the development of the Trendalyzer software, which was acquired by Google in 2007. At Google, Ola and his team delivered the Motion Chart as part of Google Spreadsheets. When Ola worked as the Product Manager for Google Public Data, he helped democratise access to public statistics by developing the infrastructure needed to make official statistics part of Google search results.

Ola and Anna went back to Gapminder in 2011 to develop free teaching materials for a fact-based worldview. In 2014, Ola coined the term 'Factfulness', which Gapminder is now promoting in order to make the education about sustainable development less ideological and more fact-based.
