How does science explain the accuracy of fortune telling?

This is a psychological phenomenon.

Bertram Fowler, an American psychologist, conducted an experiment at 1948. "It is easy for everyone to believe that a general and general description of his personality is especially suitable for him. Even if it is empty, he still thinks it reflects his personality." Psychology calls this tendency "Barnum effect".

In daily life, we can't always reflect on ourselves, nor can we always observe ourselves as an outsider, so we can only know ourselves with the help of external information. Because of this, when everyone knows himself, it is easy to be hinted by external information, get lost in the environment, be hinted by the surrounding information, and take other people's words and deeds as a reference for their actions. "Barnum effect" refers to a psychological tendency, that is, people are easily hinted by external information, which leads to the deviation of self-cognition, and think that a general and general personality description reveals their own characteristics very accurately.

On the other hand, fortune-telling, horoscope, zodiac and other predictions can also be explained by probability. Everything has two sides, so these predictions often have a 50% chance of winning. "You are very compassionate and like small animals." A popular description like this works most of the time, but there is also a 50% chance of failure.

Constellation, after all, is also summed up according to people's behavior. Don't blindly pull yourself in.
