Why do many rural divination "fortune tellers" know things like gods? How are they calculated?

I think the unpredictability of fortune-telling in rural areas is not without reason.

You said that a rural area is so big in total, and this fortune teller will always hear something about the countryside to some extent. After all, for his own work, he also needs to know the living conditions of his neighbors and what new things have happened recently. This is also the material when we write news. When he listens to these stories, it is equivalent to accumulating material. When others ask, he can quickly reflect the corresponding people and things.

Besides, we only see people who have calculated correctly, but we can't see people who have calculated incorrectly.

People have a characteristic, that is, they only pay attention to success, not to failure, only to the first and not to the second.

The fortune teller has helped others to tell their fortune many times, but just because someone wins, like a blind cat hitting a mouse, he is right about someone. Then it was widely circulated and regarded as a classic.

This is actually piled up with probability and cardinality.
