How To Make The World Add Up

Reading this in the US or Canada? Then you want the North American edition, The Data Detective.

Tim Harford is our most likeable champion of reason and rigour… clear, clever and always highly readable.”
The Times, Books of the Year

Over the past 13 years of presenting More or Less I’ve come to realise that this clear thinking is only rarely a matter of technical expertise.

Harford is right to say that statistics can be used to illuminate the world with clarity and precision. They can help remedy our human fallibilities.”
