My wife told me a story from her school days. During class, someone threw a wet sponge across the room, and it hit the chalkboard. The teacher turned around, surprised and a bit angry, but he had no idea who did it. The whole class went silent. The teacher took a deep breath and addressed the class intensely but calmly. He said, “I don’t know who threw the sponge, but I know that the actions of one person affect the entire class. I want that kid to announce him or herself now or after class or in a quiet moment. If no one steps up, the whole class will be punished with homework.” This situation closely mirrors a classic dilemma where individual and collective interests clash. It shows how the actions of one person can impact the well-being of the whole group. A friend of mine, who is a sustainability manager in a large corporation, often talks about feeling like they’re in a prisoner’s dilemma when doing their job. They need to rely heavily on trust and collaboration, which can sometimes be challenging. This reminds me of the Prisoner’s Dilemma, first formulated by Albert W. Tucker. In this scenario, two prisoners are interrogated separately and must choose whether to betray the other (by admitting how they committed the crime) or remain silent and not tell the judge how the theft was carried out. If both stay silent, they receive a light sentence as the details aren’t clear enough for a strong conviction. If one explains what happened while the other remains silent, the betrayer goes free, and the silent one gets a heavy sentence. If both admit and explain how the theft was carried out, they each get a moderate sentence.
