The subject of the talk is Street Epistomology, which is an effective conversational tool to talk to someone about their deeply held belief without turning the conversation into a debate/argument, or making either party defensive. In a short talk, often as little as five minutes, you can have someone reflect on a belief they hold with absolute certainty, and actually have them reconsider their position to the point where their confidence is lowered or they completely change their mind on the subject.
