It’s almost impossible to feel confident we’ve made the right choice when we are constantly faced with conflicting data. From choosing the right school for our children to understanding major social and political events, making informed decisions can feel overwhelming. In a world overflowing with data, it is more important than ever to decipher what the numbers tell us.

Drawing on years of work interpreting and explaining data about almost anything, renowned data journalist Kiko Llaneras offers practical tools and shortcuts to help you understand the numbers and make better decisions using a quantitative lens. Through a series of compelling examples, he reveals some of the surprising insights that a data-driven perspective can offer such as:

• What caused the Chernobyl disaster


• How Barack Obama made decisions and slept so peacefully during his presidency


• Why so many footballers are born in January

An essential guide for decoding the complexities of our modern world, Think Clearly will transform the way you view and use data in every aspect of your life.
