- (C,C)(the outcome the agents achieve)
- Notation meaning both agents chose to cooperate (the C stands for 'cooperate'); this is the mutually beneficial outcome.
- Correlated equilibria(the mechanism by which cooperation happens)
- A situation where players can receive a recommendation (like a traffic light) about what move to make, and each player is better off following that recommendation than ignoring it.
- Evolution (in this context)(how the social contract develops)
- Here, it means how strategies and behaviors gradually develop and change over time, not biological evolution.
- Game theory(mathematics and philosophy)
- The mathematical study of strategic interactions where each person's outcome depends not just on their own choices, but on what other people choose to do.
- PD (Prisoner's Dilemma)(the game structure being discussed)
- A famous scenario in game theory where two people each have to choose between cooperating or betraying the other, and betrayal seems tempting even though both would do better by cooperating.
- Skyrms(the author being referenced)
- Brian Skyrms is a philosopher who studies how people's behavior and agreements evolve over time using math and game theory.
- agents(referring to people in this philosophical discussion)
- People, or more broadly, any thinking being capable of having beliefs and making decisions.
- social contract(Rawls's interpretation of the social contract tradition)
- A hypothetical situation or thought experiment designed to uncover the most reasonable principles of justice, not an actual historical event.
