What question do you ask so that you can be sure that you know which door to open to achieve freedom?

Question

You are in a room which has two doors. One door will open and allow you freedom. The other door is blocked.
There are two guys in the room with you. They both know which door opens to freedom. One is a compulsive liar and the other is compulsively truthful. You don't know which guy is the liar or which tells the truth.
You are allowed ask one question of one of the two guys and are allowed only one attempt at opening the correct door.

Answer 1

Ask either of them which door would the other guy tell me to open and then open the other door of the answer.
In otherwords if either answers "door 1", it's door 2 and vice versa. It does not matter which one you ask as long as you remember to ask them what the other guy would answer.

Answer 2

You ask either guy what door would the other guy say is the door to freedom. If you've ask the truth guy, he'll tell the truth about the other guy's lie so pick the other door. If you've asked the liar, he'll lie about the other guy's truth, so again, pick the other door. No matter who you ask, pick the door other than the one indicated by the answerer.

Answer 3

You ask one of them what the other one would say. If he is the liar, he says the other would choose the wrong. If he is honest, he also says the other would choose the wrong. Choose the door the guy doesn't say.

Answer 4

I would study both guys for awhile first (body language, listening to their tone when they talk--high, low). How are their eyes? Do they look at you when they talk, do their eyes shift, do they look more at the floor? Do they dodge direct questions? I know this isn't real, but if you did all these things you'd make the right choice of guys.

Answer 5

if the two guys are attractive, why would i want to leave the room?
