who can figure this out first?
Six logicians finish dinner. The waitress asks, “Do you all want coffee?”

First logician: “I don’t know.”

Second logician: “I don’t know.”

Third logician: “I don’t know.”

Fourth logician: “I don’t know.”

Fifth logician: “I don’t know.”

Sixth logician: “No.”

Who gets coffee and why?

The first 5, because they would know if they didn't want coffee, and would have then said not everyone wants coffee
#5
The waitress gets coffee.

I get coffee cause I am drinking a mug right now. I like coffee because it has a bold flavour and aroma that arouses my senses. It is also a social drink as I can ask someone to come with me to get a cup and then we can socialize.

question: do you all want coffee?
"i don't know" * 5 = 0.5 * 5 = 2.5
"no" = 0

2.5 + 0 = 2.5 < 6/2
so the answer to "do you all want coffee?" is no
so nobody gets coffee

hmu if i'm right


EDIT: ACTUALLY NOPE
1-5 get coffee
because
#6 says no cos he knows not everyone wants coffee cos he doesn't
but the others only know that they personally want coffee

hmu if i'm right

The question fails to specify whether said coffee was tasty or a frappe, so you really cannot tell.

Everyone that answered the poll is wrong.

nobody because that's how logic works. if all parts of a conjunction are not true (or yes in this case), the conjunction is false. so nobody gets coffee
#13
^But there's two separate questions: will the individual have coffee and will all individuals have coffee. The answer to the first only affects the second if the individual opted not to have coffee so "I don't know" to the latter equates to "I want coffee but I don't know about the others."

Incorrect.

That's what I thought at first, but that's from the wrong perspective. The last guy is saying "No, not everyone wants coffee." He's not negating the statement "everyone wants coffee"

What? If any of the first 5 logicians didn't want coffee, they'd know that the answer is "no".

The negation of "they all want coffee" is "not all of them want coffee", and not "none of them wants coffee".

the waitress didn't say "do some of you want coffee," she said, "do ALL of you want coffee." she expressed an all-or-nothing proposition, and since the answer is not all, the answer is nothing.
#19
1-5 could've wanted coffee.

She asked "do you all want coffee?"

The first five guys didn't know since it was impossible to know until everyone else answered. The sixth and final person came to the conclusion that they don't all want coffee because he knew he himself did not want coffee and he was the last of the group to reply, making the answer "no."

It's possible that any of the 1-5 wanted/didn't want coffee though but we'll never know since they all died shortly after in an armed robbery at the diner. Sad, sad stuff, really.

That's what happens when you work in a state where marijuana is legal.

Right.

Not everyone wants coffee.


^Nah he's just saying that not everyone wants coffee, because he knows for certain that he doesn't.

The rest is true about dying and marijuana though.

We are assuming follow up questions, there is a degree of real-worldlyness to this scenario.

but the waitress didn't offer to give coffee to some of them, she offered to give coffee to all of them. since not all of them want coffee, none of them get coffee

She's asking "Do all of you want coffee"

The last guy is saying "No, not all of us want coffee" because he knows certainly that he does not.

He isn't saying "None of us want coffee"

The waitress just asked if everyone wanted coffee. She didn't make any offer.

Sentence: do you all want coffee?

Translation: does P1 AND P2 AND P3 AND P4 AND P5 AND P6 want coffee?

Due to the rules of conjunction, when not all parts of the conjunction are true, the conjunction is false. I understand that ~(everyone wants coffee) =/= everyone does not want coffee. But since she's making the offer for coffee as a conjunction (which is an all-or-nothing proposition), if there is even a single one of them that doesn't want it, then none of them get anything.

I understand that you're saying the first 5 guys said "I don't know" because they couldn't answer for everyone else, but because the last guy said no, and because the waitress asked a conjunction, the conjunction as a whole is false and nobody gets coffee.

But proggy-froggy, what nutty restaurant doesn't serve people because one person doesn't want it?

@progdude: Yeah but she's not making an all-or-nothing offer. I don't know where you got that from. She's simply asking if they all want coffee. Naturally, she'd bring coffee to whoever wants coffee because that's what waiters do.

"Do you all want coffee?" is succinctly different than, "Would any one of you logicians want coffee for yourselves?"

On these terms this is really easy, because she did not say she would get them any coffee. So we have no reason to believe that anybody is getting any coffee or that any coffee even exists, just that the first four logicians want coffee.

My poll question should've been "Who wants tasty frappe" to fit with the question more accurately. But I'm not making another thread now.

Sure, I understood that. Do you also think, like progdude, that no one gets the coffee?

Yes, but "Do you all want coffee?" is sufficiently different than "Do you all want coffee? If so, I will bring you all coffee, if not then I will not bring any of you coffee." If you assume that addition, then yes, the answer is nobody. But why would you?

Way to take a simple thought problem and turn it into a circle jerk, prog.

If I were the waitress, I'd cut into the third logician's, "I don't kn-" with, "Fuck all of you, I don't have time for this."

I mentally pictured the logicians to be a party of Mr. Pinks, so I suppose there's a personal bias against their indecisiveness. There were probably several hungry people roaming the streets that could have been in need of the small caloric intake that was squandered over their state of affairs.
