It's a truism to say that politicians lie. They twist the truth, exaggerate and spin. But blatant lying has now become the norm, led by Donald Trump and carried on by Boris Johnson and Scott Morrison. Combine this with an all-out assault on the truth in public debate along with the biggest communications revolution since the printing press, and you have a disaster in real time: a sea of fake news, hyper-partisanship and polarisation. No society or democracy can function without trust, and the consequences of this profound shift are clear. The first step to a remedy is in understanding both the liars and the enviromnents in which they lie. *Lies and Falsehoods* does exactly that, in this highly readable and incicive account of how we found ourselves in this fractured post-truth world, and how we might get out.
