Factfulness by Hans Rosling (of TED talks and Gapminder charts fame) is an exceptionally good book. It provides great insight into how to think more effectively and how to understand the reality of the world we live in (versus the large distortions so common in most people’s vision of the world). You can take a quick quiz to see how well you understand the world

The truth of the very widespread increase in wealth around the globe has influenced my investing strategy for decades. It should be influencing yours, is it?

Data is extremely valuable in helping us make decisions and evaluating the effectiveness of policy. However it is critical to be careful. It is very easy to focus on meeting targets that seem sensible – increasing the number of hospital beds – but that lead to less effective policy.

Dollar street provides photos of people at all 4 income levels from around the globe. This illustrates Hans’ point that what determines how people live and what their circumstances look like is mostly a matter of income not the country they live in. It is simple idea but one that runs counter to much of the economic discussion focused so much on national boundaries. National boundaries do matter and the laws and economic reality of the national economy has a large impact but the issues for people at each level of income are much more tied to those in their level of income anywhere in the world than they are tied to their nation.

The book relentlessly points out the great progress that has been made globally over the last 50 years and how that progress continues today and looks to be set to continue in the future. We have plenty of areas to work on improving but we should be aware of how much progress we have been making. As he points out frequently he has continually seen huge underestimation of the economic conditions in the world today. This book does a great job of presenting the real success we have achieved and the progress we can look forward to in the future.
