From the author of the bestselling The Wisdom of Psychopaths, this is a wake-up call, a groundbreaking and timely explanation of the polarization seen in some of the biggest global news stories of our times. - We isolate ourselves from people who are not the same as us. - We refuse to listen to the other side of the argument. - We think in black and white—them or us, left or right, Leave or Remain—and dangerous possibilities arise. ISIS. Brexit. Trump. The Alt-Right. We are hardwired to think in black and white, and our binary brains have led to increasingly polarized beliefs and a rising tide of religious intolerance and political extremism. But by understanding our evolutionary programming we can learn how to see the grey areas and make rational sense of our complex world. In this appeal for a better future, Oxford University psychologist Dr Kevin Dutton argues for a world in which we make subtler—and far better—decisions.
