Why do many people think it is right after seeing some constellation analysis on the Internet?

Barnum effect says that people tend to believe that a general and general personality description is especially suitable for him. Even if this description is empty, people will still think that it reflects their own personality and appearance, even if they are not such people at all. Simply put, people will only believe what they want to believe. For example, because you believe in Virgo's perfectionism, when you observe Virgo friends around you, you will only remember their nitpicking details, such as putting books exactly the same and sorting clothes by color, while subconsciously ignoring other facts, such as his computer desktop is messy. The result of this observation is that friends around you, no matter what constellation, will have the typical personality of that constellation, which further deepens your trust in astrology. If you continue to ride a bike, you will find astrological numerology very accurate.
