An intrepid academic travels the world, asking people if it is OK for someone to stab a friend in order to test the sharpness of a knife. If one person says it's OK and another says it's not OK, can both respondents be right? This video is an illustration of a multi-layered experiment designed to test the claims of several traditional philosophers that non-experts (folk) tend to hold rigidly absolutist views of morality. 3D video is used to create harmonious illusions of depth as well asynchronous left and right eye views—a fitting visual analogy for the complexity and mutability of folk moral relativism. Singer Amanda Palmer's disembodied head narrates.
