This is a book that explains clearly and not too technically why we are wrong about a great many things written by a statistician who really knows his stuff. Do you think teenage girls are getting pregnant at an alarming rate? Or that a large percentage of the prison population are immigrants? Or that global immunisation figures are pretty low? You’d be wrong in all cases. The author looks at various global issues that matter and sets us straight. He also explains much about our thinking processes, and analyses the role of social media and fact-checking in this post-truth age. In the final chapter he gives a list of ten useful things we can do to truth-proof ourselves. Of course, Donald Trump and Brexit get mentions, as do Facebook, Google, climate change, education levels, degrees of emotionality among countries and so on. It’s sane, balanced, wide-ranging and highly informative. Plaudits.
