Imagine a super-intelligent being, "Dr. Psycho," who can predict your choices with 99% accuracy. You are presented with two boxes: Contains $1,000. Box B: Contains either $1,000,000 or nothing.
Dr. Psycho has already predicted whether you will take both boxes or only Box B. If he predicted you’d be "greedy" and take both, he left Box B empty. If he predicted you’d only take Box B, he put the million inside. psycho paradox
