This is where the professor tells you that to play optimally in a game like Rock-Paper-Scissors (or soccer penalty kicks), you have to randomize. You have to calculate the exact probability (p) that makes your opponent indifferent between their options.
Let me be honest with you. I walked into my first Game Theory lecture expecting a semester of The Dark Knight . I thought I’d spend fifteen weeks watching clips of the Joker blowing up ferries and nodding wisely about "rational actors."
You learn to solve this via Backward Induction . You start at the end of the game and rewind. Suddenly, you realize the Monopolist is bluffing. A price war hurts them more than you. Therefore, the Entrant should always enter.
Here is why you should stop scrolling and actually attend (or rewatch) that lecture recording. Most economics lectures feel like history. Game theory feels like a chess match against the future.
The magic happens during the module. The professor draws a tree diagram. You have two players: an Entrant and a Monopolist. The Entrant decides to "Fight" or "Acquiesce." The Monopolist decides to "Price War" or "Accommodate."
It hurts your head. You ask, "Why can't I just pick the best option?" The professor smiles. "Because if you do, your opponent will read your mind and crush you. To win, you must be a statistically perfect slot machine."
Instead, I got a blackboard full of matrices, strange squiggly lines, and a professor muttering about "common knowledge of rationality."
It is a difficult class. It is a math-heavy class. But if you stick with it through the lecture on Bayesian Games, you will realize you aren't just learning economics. You are learning the operating system of human strategy.
