Hans Rosling : Factfulness.

Factfulness ... , a light-hearted but data-rich book, calibrates our view of the world and explains how our cognitive processes can lead us astray

Wonderful... a passionate and erudite message that is all the more moving because it comes from beyond the grave... His knack for presentation and delight in statistics come across on every page. Who else would choose a chart of "guitars per capita" as a proxy for human progress?

An immensely cheering book in these anxious times.

An assault both on ignorance and pessimism . . . helping countries improve their governance and public health and opening them up to the rule of law and market exchange works. But not by some sort of magic. Because we act. And to this, as Rosling argues, we first have to understand the world we live in.
