Through the eyes of people who became convinced of a date for the end of the world, Right Between Your Ears explores how people believe, how we turn beliefs into certainties, and mistake them for the truth. A stock trader with a young family, a philosophy student about to graduate, a retail manager who became so convinced she quit her job of 18 years. As they face the consequences of their conviction, neuroscience and social psychology offer insight into how we can become convinced we're right, even when we're wrong.
