Here’s a simplified version of the Prisoner’s Dilemma that I created for use in the classroom. The Prisoner’s Dilemma is a fundamental exercise in game theory and serves as a great catalyst for discussions about decision making, communications, ethics and responsibility.

In these examples student have to first ask the question – what information do I need to solve this problem? The textbook usually gives you that information. But here students build the problem and decide what matters. The question that’s usually buried at the bottom – it’s the last thing in the textbook problem – now becomes the first thing in the student’s mind. I want to make that question “irresistible” to the student, so they have to know the answer.
