Train tracks. Split decisions. And a philosophy humdinger worth debating. Dr. Joshua Greene is a Harvard Psychology professor, neuroscientist, and *actual* Trolleyologist. The moral humdinger that has been used in everything from Supreme Court decisions to board games 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. 

Visit Dr. Greene’s website, his charity platform Giving Multiplier, and his online quiz game Tango

Buy his book, Moral Tribes: Emotion, Reason, and the Gap Between Us and Them, on Bookshop.org or Amazon
