“You’ve come into possession of one vial of truth serum. Who would you give it to (with the person’s consent, of course) — and what questions would you ask?”
When I read this prompt I remembered an old joke.
A man asks a woman: “What can I give you to get your love?”
She answers: “Permanent anesthesia!”
In this case the woman is truthful and she answers the man’s question without hesitation.
Now, if I had a vial of truth serum it would make no sense to give it to anyone who is a truthful person.
So a right decision would be to give it to a liar.
However, can anyone believe that a liar consents to drink truth serum?
No way!
So I’ll put the vial in a vault together with a copy of the prompt!
Hopefully, in three hundred years somebody opens a vault, reads a prompt and asks: “Could it really be that there were liars three hundred years ago?!”
PURSUIT OF HAPPINESS 
I love this prompt! However, after being on the internet for all these years, I’ve decided there are just some things I don’t want to know. Lie to me, please 😉
Sorry, hate liars!
Sounds scary… Don’t try once spouse 🙂

Loved the joke! And I feel that with time number of honest people will only dwindle. But you sound optimistic about future generations! Kudos!
LOL – great joke. I imagine the only person willing to give consent to taking truth serum would be someone hoping the truth could set them free of some crime etc. I like your optimism for the future…… 🙂
Good idea about innocent to be executed. He asks for truth serum, tells the truth
and then …they hang him! As re optimism: let’s see! 😉
That’s clever. I think lying is a part of human nature, so you may have more candidates right now than you realize!
I am an optimist… but in my page “Quotes” you can find many posts for
different occasions. Here is one of them:

It’s important how dangerous a liar is!
A good question… how do you know the person is truthful to begin with?
Some axioms are proved logically. Liars will not agree to take truth serum.
So I don’t need to have a method of finding of a truthful person.
Ah, I see.
