How to Make the World Add Up Ten Rules for Thinking Differently about Numbers

In How to Make the World Add Up, Tim Harford draws on his valuable experience as both an economist and presenter of the BBC's radio show More or Less. He employs an easy to follow mix of anecdotes to highlight wider truths about how we are taken in with:
. disinformation,
. bad research, and
. misplaced motivation.

The message is:
. be aware of your cognitive biases,
. identify thinking errors and to update your predictions.
. understand when you use heuristics (trial and error, a rule of thumb or an educated guess)
. establish how the data is being interpreted and look beyond it

Straightforward and to the point really.
