An entertaining guide to human nature that reveals how people really make big choices.

What makes somebody change their world view completely? Why do some people refuse to alter their perceptions, despite prevailing evidence that says they should? And how can you persuade them to change their minds? Eleanor Gordon-Smith meets six ordinary people who made life-altering decisions.

From the woman who realised her husband harboured a terrible secret, to the man who left the cult he had been raised in since birth, and the British reality TV contestant who, having impersonated someone else for a month, discovered he could no longer return to his former identity, all of the people interviewed radically altered their beliefs about the things that matter most. Their stories explore the limits of human reason and persuasion.
