What makes some people more generous than others? And when it comes to altruism, how do we get more of it? In this episode, we learn about how altruism works in the brain, and the clues are surprisingly found in how psychopaths experience fear. Neuroscientist and professor Abigail Marsh will tell us what she's learned about altruism and the human brain.

Her book: The Fear Factor: How One Emotion Connects Psychopaths, Altruists, and Everyone In-Between
Published by Dr. Marsh in 2017 "What is responsible for the extremes of generosity and cruelty humans are capable of? By putting psychopathic children and extreme altruists in an fMRI, acclaimed psychologist Abigail Marsh found that the answer lies in how our brain responds to others' fear. While the brain's amygdala makes most of us hardwired for good, its variations can explain heroic and psychopathic behavior."
TED Talk: Abigail Marsh asks an essential question in her TED talk: If humans are evil, Why do we sometimes go to extraordinary lengths to help others even at a cost to ourselves?
Matthieu Ricard: Points out that empathy on its own can lead to fatigue and burnout.
Michael Krauss: Research shows that increased wealth can actually reduce empathy and altruism.
David DeSteno: People who've experienced significant trauma or natural disasters themselves benefit from self-efficacy, which gives them the confidence to know what to do in a situation they are familiar with.
