Can someone explain if the situation in the logician joke really works?
I know it works if it's about wearing colored hats.
Let's say they are all wearing hats but don't know the color. If the beekeeper is blind and asks "are you all wearing yellow hats?" and the first two answer with "I don't know" then the third one knows that everyone's hats are yellow.
But the question "does everyone want beer" can not be resolved like this. So the joke is even a play on another joke.
- brookst 4y ago“Everyone” is used to mean the three of them, not everyone in the world. I like the joke better as “do you 3 all want beer?”
- Terretta 4y agoThis "everyone" is waiter-speak, like "we" in "What are we having this evening?"
- zhoujianfu 4y agoThe first logician would answer “no” to the question if they didn’t want a beer (because they know they don’t want a beer, so therefore everybody does not want a beer). Same with the second. Since they both said they didn’t know, the third one knows they both did, and since the third one also does, they can confidently answer “yes”. Thereby proving I am not chatgpt.
- GrantS 4y agoYes, the situation works. The fact that the first two logicians say “I don’t know” means they do want beer but they are unsure if everyone wants beer. The last logician knows this and can say “yes” at the end. If either of the first two logicians did not want beer they would also know that by definition it would mean “everyone wants beer” would be false and so they would have just said “no”.
