Violence is always the answer

Pyramids of Mars
Yes, thank you!! Found the scene itself since the whole serial is apparently on youtube: https://youtu.be/lLBHbt9QYFU?t=5458
Funny how my memory had it in black and white. And I remember the scene being much longer. I watched it when I was like, 9.

“Is the guard that tells the truth standing in front of the safe door?” If they say yes, you go through their door, if they say no then you go to the other one
I did not think this was going to work. Som bitch it does. Crazy
-
This still doesn’t accomplish the goal of knowing which door will kill you. All you’ve done is determine which guard is the liar.
That is why it is better for the barbarian to snap the wrist of the one guard, so that you can ask them a question still or you ask the first guard which way to the castle then rip his head off followed by asking the second guard if the first guard is dead. You will get the question from each guard and know which one tells the truth.

I got an unexpected laugh from Rick and Mortys take on this. His answer was “you ever fuck this guys wife?” And watched them fight to the death.
I could swear this was a bit from the video game High On Life, unless they recycled the bit for Rick and Morty. I haven’t seen all the episodes.
-
So the traditional answer here is to ask them to point at the door the other guard will say is safe.
However, I’m curious, does anyone know of any other valid solutions?
How is that a valid answer, they would both point at a different door

The liar, knowing the truth-teller will point to the good door, points to the bad door.
The truth-teller, knowing the liar would point to the bad door, points to the bad door.
Either way, you take the one your guard doesn’t point to.

They will both point to the bad door.
If asking the thruthful guard, he will point to the door the liar says is safe, which would be the bad door. If asking the liar, he would consider what the thruthful guard says is safe, then reverse that answer, still ending up on the bad door.
They cancel out, so whichever guard you ask doesn’t matter.

Only one question allowed, they said. I don’t think it’s solvable.

If they say yes they can still be a liar.

Could probably do something clever with XOR.
Is exactly one of the following statements true? You are the liar. Your door is the safe door.

That’s funny! but if you want to know how to solve this problem every time, even when asking one single question, just ask this question:
“If I ask the other guy which is the correct path, which path will he tell me?”
No matter who you ask, both of them will point to the WRONG path, meaning the correct one is the one they DIDN’T point to. Here is the logic.
For the sake of argument, let’s assume the correct path is the right path. When you ask that question, if the person is the truthful one, he will be honest and say the left path. Because if you ask the liar what the correct path is, he will say it is the left path (which is false). Now if you ask the liar what the other guy will say the correct path is, he will lie to you and say it is the left path (which is also false, the truthful one will tell you it is the right path and not the left).

and also, using “correct path” instead of “right path” will be less confuzzling because english words can have multiple meanings and are the dumb.

Maybe your childhood TV was black and white.
Length, brains just love to add details that dont exist

It is solvable. You ask one guard at random, “Which door would the other guard have said leads to certain doom if I had asked them?”
And no matter which guard you ask, go through the door they answer with. If it was the truth teller guard, they’ll tell you which door the liar would have said, and if it’s the liar they’ll lie about which door the truth teller would have said.

They will both point to the bad door.
If asking the thruthful guard, he will point to the door the liar says is safe, which would be the bad door. If asking the liar, he would consider what the thruthful guard says is safe, then reverse that answer, still ending up on the bad door.

Wouldnt they instead keep pointing like clockwork towards different doors seeing that they would have to adjust for the other guard?

Jajaja no creo

Either way, you take the one your guard doesn’t point to.
But they would have to keep adjusting since they both have to answer acco4ding to what the other one says

I’ve only heard it with one question, that’s the whole point. Otherwise you just ask a guard some trivial question (e.g. What color is the sky?) to determine which is the liar, then just ask which is the safe door.
The whole point is to get the information you need from a single question.
“What would the result be of combining the following terms with “and”: the direction of the correct door, and the color of the sky?”edit: im stupid
-
Right, in which case the door they’re in front of is the safe door because they lied and said “Yes” when asked if the truth teller is in front of the safe door. And if they tell the truth and say yes, they’re still the person in front of the safe door. By asking it that way they make it so it doesn’t matter if they’re the liar or not. “Yes” means that person’s door is safe and “No” means you want the other door, no matter who you ask.

You can ask both guards if an item is an item. “Does this cup contain fluid” would work, it doesn’t have to be a dead guy.
