Your brain makes countless moral decisions every day ... but have you ever wondered where your morality comes from? Through thought-provoking games and moral dilemmas, such as the "Trolley Problem", we'll test the strength of your moral fiber. What would you do if an out-of-control train barrels down the tracks toward four people? You can save them by diverting the train to another track, but one problem - a person is standing on the second track. Who would you sacrifice? Morality isn't always black and white. We'll test that theory in a series of interactive games and hidden camera experiments.
