It’s good for the aha intuition moment for some people. It’s the thing that made me get it as a kid. There’s something unsatisfying about it though. You can have 100 doors, and open 98 to leave the initial guess and 1 more. But this is scaling up the rule as “all but one”. I don’t see an obvious reason that the rule shouldn’t scale up as “open one more door”. Then you have 99 closed and 1 open and the result isn’t nearly as obvious, even though switching is the better move.
- diputsmonro 3y agoI agree that it feels weird at first, but thinking about it this way fixed that for me: The whole reason for the apparent paradox is having the "50/50" choice at the end. You either keep the door you picked, or swap with the other door, so it feels like no advantage. If they only revealed a single door, then you would have multiple doors to swap to, so you wouldn't have the "50/50" choice. The only way to keep the "50/50" choice at the end is to reveal all but one door and give you the option to switch to it.
- moffkalast 3y agoYeah I thought about that, both +1 door and infinity-1 door options are both equally unfaithful to the original I suppose. Keeping the 50% door opening ratio would make more direct sense if you wanted to scale it up for other reasons, but isn't nearly as clear in intuitively showing the concept.
