No need to answer

[bonanova]

Somewhere in the vast reaches of the ocean, there is a very strange island known as the Island of Questioners. It derives its name from the fact that its inabitants never make statements, they only ask questions.

The inhabitants ask only questions answerable by Yes or No. Each inhabitant is one of two types, A and B. Those of type A ask only questions whose correct answer is Yes; those of type B ask only questions whose correct answer is No.

For example, an inhabitant of type A could ask, "Does two plus two equal four?" But he could not ask whether two plus two equals five. An inhabitant of type B could not ask whether two plus two equals four, but he could ask whether two plus two equals five.

I once visited this island and met a couple named Ethan and Violet Russell. One morning Ethan asked me, "Are Violet and I both of type B?" Since I am not an inhabitant of the island, I may now ask you, and you now may answer, What type is Violet?

[Pankaj Varma]

Both cannot be type B because then answer will be Yes which is not allowed

Again Ethan cannot be type A since the answer is not Yes.

So Ethan is B and Violet is A

Poor Questioners. They cannot speak anything but questions and then only those for which they already know the answers. How do they exchange any information at all?

I happened to overhear this conversation between Violet and Ehan:

- Do you wnat a steak for dinner, dear?
- If I don't say I do, would you give it to me anyway?
- You'd rather go hungry than ask nicely, would you?
- Did you even cook anything today?

Violet is type A

Can we conclude that a request for confirmation of a premise by a type A questioner is equivalent to the assertion of that premise by a truth teller? In answering that question assume that I am type A.

Is it impossible to conclude that a request for rejection of a premise by a type B questioner is equivalent to the assertion of that premise by a truth teller? Are both myself and bonanova type B?

Able: "Why does a Q always answer a question with another question?"

Baker: "Why shouldn't a Q always answer a question with another question?"

You people are making this too complicated =) Let's say that a speaker wants to convey the statement "I want dinner now".

If the speaker is type B, he should ask "Is the sentence 'I want dinner now' grammatically incorrect?"

If the speaker is type A, he should ask "Is the sentence "I want dinner now' grammatically correct?"

There might be some work getting all the denizens familiarized with this convention, but the bonus is that once established, the convention does not require a speaker to first identify whether he is type A or type B.

Do you mean that for asking questions rather than making statements, Questioners must develop a nested question convention?

Does the question: “Is X=1?” asked by A establish the value for X, whereas the same question asked by B leaves the true value of X wide open? Therefore, is it important to be aware of the type of the person that you converse with?

Was the question in the OP a way of introduction advising Bonanova of the true orientation of his new acquaintances?

Why everyone here chooses type “A” for their own identity? (Oops, that was an illegal question.)

More elegantly, Ethan could relay his wishes to Violet like so:

“Would I be lying if I said, wanted steak for dinner?”
