Train tracks. Split decisions. And a philosophy humdinger worth debating. Dr. Joshua Greene is a Harvard Psychology professor, neuroscientist, and *actual* Trolleyologist. This thought experiment pops up in everything from policy discussions to board games and looks at: What makes you a good person? How do you reason with people who make you scream into a jar like Yosemite Sam? How far would you go to save others? Which charities should get your money? What is active versus passive harm? And what would a monk do? Also: how neurodivergence influences moral decisions, religion used as a moral compass, and your new favorite skeleton on the planet.
