Self Referential Undecidability Construed as Incorrect Questions

[Sculptor]

Will Jack's answer to this question be no?

Is not even a question that can be directed to Jack.

Sure it is. It would be more commonly phrased as
Will your answer to this question be no?

That is a different question.
And like the other one it is objectively meaningless.

Yet referring to Jack in the third person when speaking with
Jack is not semantically incorrect, it is merely unconventional.

It's rubbish

[PeteOlcott]

I don't care about your proclamations.

Jack can answer "no" to the question. Why is this answer by Jack correct; or incorrect?
Jack can answer "yes" to the question. Why is this answer by Jack correct; or incorrect?
Olcott can answer "yes" to the question. Why is this answer by Olcott correct; or incorrect?
Olcott can answer "no" to the question. Why is this answer by Olcott correct; or incorrect?

You deceiptfully changed this question:
Can Jack correctly answer “no” to this question?

Here is the original PhD computer science professors answer:
Can Jack correctly answer “no” to this question?

Let's ask Jack. If he says “yes”, he's saying that “no” is the correct
answer for him, so “yes” is incorrect.

If he says “no”, he's saying that he cannot correctly answer “no”, which
is his answer. So both answers are incorrect. Jack cannot answer the
question correctly.

Bullshit.

Those were the words of a PhD computer science professor that has been
published several times in several very highly esteemed computer science journals.

So what?

Ask him to translate his question in a query language.

If the question is "incorrect" then the query parser should reject it on some grounds.

I have already shown (in other posts in this forum) that an
isomorphic question posed to Prolog is rejected on the basis
that unify_with_occurs_check/2 recognizes that terms with
pathological self-reference must be rejected as invalid.

Can Carol correctly answer “no” to this question?
Any genius can easily tell that when Carol's question is
posed to Carol both "yes" and "no" are the wrong answer.

It depends on how you define the predicate "correctly"

Clearly you are not a genius or are pretending to be much
dumber than you are as an excuse to be disagreeable.

I am neither agreeing nor disagreeing.

I have no idea what your question means until you define the term "correctly".

So you have no idea than when a yes/no (technically polar) question has a correct
answer of "no" and someone answers "yes" they they provided the wrong answer?

The only correct answer is "no". Do you understand this?

Why are you asking me this?!? You are the person who formulated the question!

Surely you know what you mean by "correct"?

Are kittens a type of fifteen story office building?

Maybe. Show me the type-definitions for both.

The only correct answer is "no".
Do you understand this?

No (the only correct answer).

Q.E.D

[PeteOlcott]

"This sentence is not true." is a self-contradictory expression
that an incorrect statement. The same reasoning equally applies
to self-contradictory questions.

When a yes/no question lacks a correct answer from the solution
set of {yes, no} then this is defined to be an incorrect question.

When a decider/input decision problem instance lacks a correct
Boolean return value from the decider then this is defined to be
an incorrect question for this decider.
