Replaying old games that I have fond memories of. We’re in an incredible renaissance of classic games getting source ports or updates that bring them up to modern standards, and I’m loving it. Daggerfall, Blade of Darkness, Jagged Alliance 2, Morrowind, Jedi Knight, Caesar 3… I’m sure I’m forgetting some many. They let me forget the present and pretend that I’m back in simpler, happier times, at least for a little while.
I have a sinking feeling he might have made a mistake.
No information regarding the machine’s accuracy is provided, but the fact that you are asked to make a choice implies that it is not perfect. The question explicitly specifies that the prediction has already been made and the contents of box B have already been set. You can’t retroactively change the past and make the money appear or disappear by making a decision, so if your choice must match the prediction, then it’s not your choice at all. You lack free will, and the decision has already been made for you by the machine. In that case the entire question is meaningless.
Both! Critically, the contents of box B depend on the machine’s prediction, not on whether it was correct or not (i.e. not on your subsequent choice). So it’s effectively a 50/50 coin toss and irrelevant to the decision-making process. Let’s break down the possibilities:
Machine predicts I take B only, box B contains $1B:
Machine predicts I take both, box B is empty:
Regardless of what the machine predicts, taking both boxes produces a better result than taking only B. The question can be restated as “Do you take $1M plus a chance to win $1B or would you prefer $0 plus the same chance to win $1B?”, in which case the answer becomes intuitively obvious.
I’ve never heard that before. What I have heard several times is that text is not static, so if you read something, look away, and then read it again, it’ll say something different. That I can corroborate, along with the idea that this is how you realize you’re in a dream and induce lucid dreaming.
