Every day, we suffer a barrage of information about the threat of terrorism, war and apocalypse. But while we are preoccupied by our fears, the real risk of these obscure annihilating events taking place is about as likely as winning the lottery. In this ground-breaking new book, Dan Gardner explains our 'risk perception' through our brains' two simultaneous responses to risk the ancient 'fight or flight' instinct and the rational considered response. How do we make choices amidst the bombardment of information we experience every day? And to what extent is that information manipulated to provoke a particular reaction from the public? To discover the answers, Dan Gardner speaks to economists, politicians, psychologists and media commentators, with entertaining and often surprising results.
