Ologies with Alie Ward
Trolleyology (MORAL DILEMMAS + THE TROLLEY PROBLEM) with Joshua Greene
20 Aug 2025
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.

Full Episode
Oh, hey, it's that guy at the coffee shop overthinking his milk choice, Allie Ward. This is not one you saw coming, is it? Unless you're either a Harvard and Princeton-trained philosopher and academic. But my guest is a Harvard and Princeton-trained philosopher and academic. He's a member of the Center for Brain Science and a professor of psychology at Harvard.
He's dedicated his life and career to the psychology and the neuroscience of how the brain forms complex ideas. and makes choices and uses real, real philosophical humdingers in his analyses. And one of the courses he teaches is titled Evolving Morality from Primordial Soup to Super Intelligent Machines. And he wrote the book Moral Tribes, Emotion, Reason, and the Gap Between Us and Them.
Now, during this interview, we chatted via a video call and I had to ask the guest a few times to make sure that the collar of his shirt wasn't rubbing on his mic. And the best solution was to undo a couple of shirt buttons and like splay his collar out like he was going to saunter onto a dance floor in Miami. And he seemed genuinely mortified by it. But I like to think that it made for
a super casual vibe. This is such a fun conversation. Never did you think gruesome philosophy could be this engaging and friendly. But the moral thought experiment that's now known as the trolley problem, it originated with this English philosopher, Philippa Foot, who wrote on virtue ethics.
Like if a streetcar or a trolley is careening on a track that splits, is diverting it to kill fewer people ethical? Philosopher Judith Jarvis Thompson used that example in 1976. after Philippa did and coined it the trolley problem. So we're off to these like streetcar races.
And the trolley problem examines morals and ethics and utilitarianism and religion and sacrifice and how to look at the principles of the greater good. Also looks at neuroscience. So we're going to get into that. But first, thank you so much to patrons of the show who support us for a dollar or more a month and submit questions for Theologist before we record.
Thank you to everyone out there wearing Ologies merch from ologiesmerch.com. And thank you to everyone who leaves reviews of the show, which keeps it up in the charts. And also I read them all, such as this recent one from KWZ New York who wrote, come for the science and fun facts, but you'll leave with one remarkable example after another of human beings who care deeply about the world.
So thank you KWZNY for caring enough to submit a review. I read every single one. So keep them coming and know that they make your internet dad. the lady named me, cry sometimes. Also, if you do need any shorter, kid-friendly, non-swearing episodes, you can find those in their own feed. Wherever you get podcasts, they're called Smologies, S-M-O-L-O-G-I-E-S.
Okay, let's get into what makes you a good person? How far would you go to save others? Which charities should get your cash? Why are the political divides killing people? What is active versus passive harm? What would a monk do?
