Despicable Me (3)
Editor: Sigma
During game shows, host would employ the same trick. If there were three doors at the set, the host would tell the participant that a brand-new car was behind one door, and the other two would lead to nothing. He would then allow the participant to make the choice.
Say the participant chose the first door. Then, the host, knowing where the car was, would go to the third door and open it, revealing nothing. The host would turn to the participant to ask, "Do you still want to choose the first door? Would you like to change your choice?"
Most people would not change their choice, either out of fear or stubbornness, believing the host was employing reverse psychology, trying to trick them. But in reality, no matter where the car was, abandoning all emotions, with only statistics as the basis, one should always change to the second door.
