Psychologist Abigail Marsh was only 19 years old when a stranger saved her life. This transformative event sent her on a trajectory to discover what makes some people put their own well-being at risk for strangers. Functional magnetic resonance imaging (fMRI) brain scans of psychopaths and extraordinary altruists led to a major discovery: The most powerful predictor of altruistic behavior is the ability to recognize fearful facial expressions. Psychopaths lack this ability and have a muted fear response themselves, but extreme altruists show a heightened reaction. Marsh brings laboratory research to life. Her underlying message is one of hope and faith in the goodness of humankind. Readers interested in what makes polar opposites like the Hannibal Lecters and the Mother Teresas of the world tick will relish this eye-opening psychology detective story.
