This episode explores one of the most intriguing questions in human psychology: why do some people show extraordinary compassion while others display extreme callousness? Featuring renowned neuroscientist Dr. Abigail Marsh, the video dives into cutting-edge research comparing the brains of highly altruistic individuals—such as anonymous organ donors—with those of people who exhibit psychopathic traits.

Dr. Marsh explains how differences in the amygdala and related neural networks influence fear perception, empathy, and social decision-making. The discussion examines what neuroscience reveals about moral behavior, emotional sensitivity, and the biological foundations of kindness. Viewers will learn how genetics, environment, and brain structure shape a person’s capacity for compassion—and why both extremes of the spectrum provide valuable insight into human nature.

The conversation also explores practical ways to become more empathetic, highlighting evidence-based habits that strengthen prosocial behavior and emotional resilience. Whether you're interested in psychology, neuroscience, mental health, or simply becoming a better human being, this episode offers a clear, authoritative look at how our brains guide the way we treat one another.
