First of all, the description of constellations is generally in line with their own.
This is probably the Barnum effect, which means that people are more likely to believe some general personality descriptions, and constellation books will also write some personality descriptions that everyone has in order to give people a particularly accurate first impression. You can't deny it the first time, so you will believe it.
The second is confirmatory bias. People tend to look for evidence to support their own views and selectively ignore some different views. Look on the bright side of your wishes and ignore the bad ones. The description of the constellation's personality will always lead us to look for memories in the memory according to the direction he gives.
The final Rosenthal effect. Simply put, it is psychological suggestion. Allow yourself to develop into a character that conforms to the horoscope description, and you will really become the kind of person described in the horoscope book. Over time, this puts a mask on yourself.
People who believe in constellations probably want to become a really beautiful state described in a constellation book. I don't like myself now. There is nothing wrong with making yourself better.
