borkcorkedforks,

Both, safer bet.

If the prediction is at all accurate there is a good chance I get nothing.

Double_A,

To throw some extra spice in this: What happens if the player decides to chose randomly?

IsThisLemmyOpen,

It depends. If you mean flip a coin, then you should know that no coin flip or dice roll is truely random, it is random to us only because we couldn't predict it with our current technology. This scenario assumes that there are machines in the world that can predict the future, we just don't know whether this particular machine is accurate or not.

Now if you are talking about quantum-based randomness, I mean... I think the machine could just put $0 in the second box just to fuck with you.

I’d take both boxes.

We’ve been given no information on the accuracy of the machine’s predictions. Therefore, we have to assume it has just as good of a chance of being wrong as being right. There’s essentially a 50/50 chance that box B has $1,000,000,000 regardless of my choice, so I would choose the option that at least guarantees the smaller prize while still giving me the same chance at the larger prize.

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:

  • I take B only - I get $1B.
  • I take both - I get $1.001B

Machine predicts I take both, box B is empty:

  • I take B only - I get nothing.
  • I take both - I get $1M.

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.

FlowVoid,

But if it's true that the machine can perfectly predict what you will choose, then by definition your choice will be the same its prediction. In which case, you should choose one box.

Though OP never actually stated that the machine can perfectly predict the future. If that’s the case, then yes, you should just take box B. But we’re not given any information about how it makes its prediction. If @Sordid is correct in assuming it’s a 50-50, then their strategy of taking both is best. It really depends on how the machine makes its prediction.

FlowVoid,

It's much easier if you reframe the problem:

Someone says they've built a machine that can perfectly predict what you will do. Do you believe them?

If so, take one box.
If not, take both boxes.

But even if you don't believe them, it's got a 50% chance on a coin toss.

FlowVoid,

Regardless of whether the machine is right, if you don't believe it can perfectly predict what you'll do then taking both boxes is always better than just one.

mr-strange,

Yeah, at least you'll have an extra box to keep your stuff in.

Hudell,

I would assume the machine would predict I take both because it would know me too well to belive there would be anything in B, so I would take A.

autumn,

Does the machine know that box is not an option? Thinking that A, A+B, and B are all valid options is something I could see an AI doing.

There also isn't much penalty for taking A+B? You'll always get at least $1M. And if you took only B, the max you could get is $1M.

Edit: I can't read lol. I'd still take both, the result is

Predicted A+B: $1M

Predicted B only: $1001M

If you only take box B, the result is

Predicted A+B: $0

Predicted B only: $1000M

IsThisLemmyOpen,

I think the machine predicts 2 results, either

Box A is taken = True

OR

Box A is taken = False

Something like:

If (Box A Taken = True)
{place ($0) in Box B}
else
{place ($1,000,000,000) in Box B}

Machine doesnt care if you also take Box B, it only cares if Box A is one of the boxes taken. If you take no boxes, Box B would still have a billion dollars, although thats kinda dumb choice from a gameshow host's perspective.

kakes,

Box A and B hands down. 1,000,000 birds in the hand are worth 1,000,000,000 in the bush.

XPost3000,

Both, like a million dollars guaranteed I could live a comfortable life with that

Moghul,

A and B every time because if the machine "predicts" you take both, you get 1kk usd, if the machine "predicts" you take only B, you get 1.1kkk usd. It's a free million dollars at least. Buy a house and invest the rest.

technopagan,

Box A only because ain't nobody got time for any "Paradox" BS & daddy's got bills to pay. Trick someone else with all that Time Travel nonsense!
