Barnum constellation effect

Why do some people believe that people can judge their character through constellations? -Barnum effect

Just like judging personality by blood type, it is a general description that can be applied to anyone, but people just think it describes themselves. This psychological phenomenon is called Barnum effect.

Someone once did an experiment to describe the personality description of type A blood as the personality of type B blood, and then showed it to people with type B blood. As a result, about 90% people think that their personality is very consistent with the description. When you hear people say that you want to be recognized by people around you, that you have a romantic side, and so on. Even if you don't think it's suitable for you, you rarely refute it, say it wrong or your statement is too unclear. Many times, people will agree and answer: yes.

The above is quoted from the book Psychology of Interest.

People often think that a general description of personality reveals their own characteristics very accurately, which is called Barnum effect in psychology.

It is easy to believe that a general description of his personality is particularly suitable for him. Even though this description is empty, he still thinks it reflects his personality. There was once a psychologist who used a common sentence that was suitable for almost anyone to let college students judge whether it was suitable for them.
