Prisoner's Dilemma

Why Use It

Whether you're leading a team, building a product, or just trying to argue less at dinner, there's a mental model for that. Probably several, actually.

When to Use It

Pay attention to recurring challenges in your work and personal life. When you notice yourself stuck in the same loop, that's your signal to apply a structured thinking tool rather than relying on gut instinct alone.

Start by mapping your most frequent decisions to the models that address them. Over time, this becomes second nature, like a chess player recognizing board patterns without conscious effort.

How to Use It

Apply the model to a specific situation you're facing right now. Start small, observe the results, and gradually expand your use across different areas of your life and work.

The most effective approach is deliberate practice: pick one model per week, apply it consciously to every relevant decision, and reflect on what you learn at the end of each day.
