Newcomb’s Problem

Newcomb’s Problem is a thought experiment about decision-making and prediction. You face two boxes: one transparent with $1,000, and another opaque, which may contain either $1 million or nothing. A highly accurate predictor has already foreseen your choice—either taking both boxes or only the second. If they predicted you'll take both, the second box is empty; if they predicted you'll only take the second, it contains $1 million. You must choose: take both boxes or only the second. The dilemma explores whether to trust the predictor’s foresight or prioritize immediate gain.
