Contributor(s): Evan Davis | Never has there been more concern about dishonesty in public life. From President Trump to the Brexit debate, we hear constant talk of falsehoods and fake news, and appeals to alternative facts. In his new book, Post-Truth: Why We Have Reached Peak Bullshit and What We Can Do About It, which he will discuss at this event, Evan Davis steps inside the panoply of deception and spin employed not just in recent politics, but in all walks of life to explain why bullshit is both pervasive and persistent. Drawing on behavioural science, economics, psychology and his knowledge of the media, Evan will discuss why bullshit has apparently become the communications strategy of our time.
