Black hat fortune telling _ Is black hat lucky?

Why do people in black hats say they are smart?

There is such a story in the legend:

There is a Turkish businessman looking for an assistant. Two people came to "apply", and the businessman wanted to test who was smarter.

The businessman took the two of them to a room, which had neither mirrors nor windows. The businessman lit a lamp for lighting, then put a box with hats in front of two people, opened the lid and said, "There are five hats in it, two are red and three are black. Now I'm going to turn off the lights. " Then the light went out, and the room was dark and nothing could be seen. The businessman went on to say, "Now each of us takes out a hat from the box and puts it on our heads." After three people put their hats on their heads in the dark, the businessman put the hat on the box again, lit the lamp and said, "Please tell me the color of your hat as soon as possible."

As soon as the light came on, both of them saw that the businessman was wearing a red hat, while the other man was wearing a black hat. What color hat should he wear on his head? Black? Or red?

Only after a while, one of them said excitedly and confidently, "I'm wearing a black hat!" " "This man is right, the businessman hired him.

Why can he tell the color of his hat quickly and definitely?

He thinks like this: there are only two red hats, and the businessman has already worn a red hat on his head. If I wear a red hat on my head, the other person can immediately judge that he is wearing a black hat without hesitation. However, the other party didn't say it immediately after the light came on. At this point, I can be sure that I am not wearing a red hat. It is because I wear a black hat that he has the same consideration and hesitation as me. I made this judgment when the light was on and the other party was still hesitating.

This analysis and judgment is convincing. Can you think like a wise man?
