I was looking up thought experiments on t’Internet last night. Look I do these sorts of things, OK. I found this one which I’ve read before and thought I’d post it to see what you lovely blogging folk would say.
In an ancient land a “semi-barbaric King” rules. He has an unusual form of trial justice for criminals. Place the accused in an arena with two exits. Behind one door was a beautiful woman and behind the other was a ravenous and slightly annoyed tiger. The accused is given the choice of picking only one door.
The door with the woman behind it leads to a declaration of innocence and as a reward he was required to marry the woman, regardless of previous marital status.
The door with the tiger behind it leads to a messy and noisy death as punishment for his crime. Clearly he is guilty if he makes such a bad decision.
One day the king found that his daughter, the princess, had taken a lover far beneath her station. The king, not being a progressive ruler, threw the man in prison and set a date for his trial in the arena. When the trial day arrives the man looked to the princess for some indication of which door to pick. The princess knows which door leads to the woman and which door leads to the tiger but is faced with a conundrum. If she indicated the door with the tiger, then the man she loved would be killed on the spot; however, if she indicated the door with the lady, her lover would be forced to marry another woman and even though he would be alive she would never be with him again. Finally she does indicate a door, which the suitor then opens.
The question is: Did the tiger come out of that door, or did the lady?
