  1. Cooperate vs Defect mechanism

    In repeated interactions, cooperation preserves a shared surplus, while defection trades that continuing value for an immediate private advantage—and invites retaliation that can leave both sides poorer.

  2. Tit for Tat principle

    In repeated trust games, begin with cooperation, then copy the other party’s previous move. This makes cooperation rewarding and defection costly without turning one betrayal into permanent hostility.

  3. Trust but Verify principle

    Begin with trust to make cooperation possible, then update that trust using evidence of how the other person behaves. This avoids both naive exposure and permanent suspicion.

  4. Low-Trust Society domain

    A low-trust society can manufacture the selfishness it expects: people defend, withdraw, or defect because they anticipate others doing the same, making cooperation fragile and costly.

  5. Prisoner's Dilemma mechanism

    Prisoner's Dilemma is the trap in which protection against expected betrayal makes mutual betrayal the rational choice. Cooperation produces the better shared outcome, but defection offers safety—or a tempting private gain—when you cannot trust the other side to cooperate.

  6. Payoff Matrix mental-model

    A payoff matrix exposes the structure of a strategic choice by mapping every combination of players’ actions to their respective outcomes. It reveals when individually tempting moves produce a collectively worse result.

Description

What is prisoner's dilemma in game theory? In this episode of FutureIQ, we explain the concept of Prisoner's Dilemma in game theory, a scenario where two rational individuals may not cooperate, even if it appears to be in their best interest. We provide an overview of what Prisoner's Dilemma is, how it applies in economics, and what the game entails. Using real-life examples, we illustrate how this concept applies in situations such as business, politics, and even personal relationships. We also discuss how to win at Prisoner's Dilemma and the implications of the game for future interactions. By the end of the episode, you will have a clear understanding of the theory and how it can be applied in various contexts. Hope you enjoyed FutureIQ by Navin Kabra and Shrikant Joshi.
