think about it.

Lie Detectors.

For instance, if you were hooked up to the lie detector and you were asked: "Are you a liar."

You could say: No, and it would beep. Yet if you said No, there is a chance it won't, meaning that there is an answer.
You could say: Yes, and it would beep. Yet if you said Yes, there is a chance it won't, meaning that there is an answer.

There is a correct answer to every question, you just need to think outside the box, but I like your train of thought. You actually had me there.

I don't know if you understand my thought

I mean as in literally there is no right answer

as in the direction

Well:

Are you a liar? ➜ Yes ➜ Not lying
Are you a liar? ➜ No ➜ Lying
