Welcome to the game of doors!! Anchor: Alright then, you have three doors in front of you, A, B, C. Two of these three contain nothing, one contains the proof of the unified theory yet unknown to man . You can choose any one door, which one do you choose? You: Uhmmm.. I think I'll go with door A Anchor: Are you sure? You: Yeah! Anchor: (opening door C) Well well, there is nothing behind door C! Arent you glad you didnt choose that door? You: (wiping the sweat off) Yeah! Now show me whats behind door A. Anchor: Wait a minute, what if I made you an offer. Would you like to change your door? Would you like to choose door B instead? You: (Damn, I should have paid attention to those undergrad probability lessons!!) Uhmmm.. I dont know... I think I will go with what probability tells me. Lets ask the folks over at Physics Forums what they think? Should I change doors or stick?
