Join host Jason Silva in a series of interactive games and experiments that explores your brain's capacity for compassion, and questions the motives behind both your selfless and selfish acts. In this episode we'll tackle the age-old question of nature vs. nurture, and test whether altruistic inclinations are hardwired in our brain from birth. You'll discover if you're actually born naughty or nice, and explore the chances of finding a psychopath among your family or friends — or even in the mirror!
