What is the constellation based on to calculate personality?

In fact, a large part of the constellation is Barnum effect, which is a bit like everyone. Many times, everyone will sit in the right place, and everyone will easily believe that a general personality description is especially suitable for him. Even though this description is empty, he still thinks it reflects his personality.

You really need others to like and respect you. You tend to criticize yourself. You have many abilities that can be your advantages, but you also have some shortcomings, which can generally be overcome. Although you look calm on the outside, you are really anxious on the inside. You sometimes doubt whether your decision or behavior is correct. You like some changes in your life and hate being limited. You are proud of being able to think independently. Without sufficient evidence, you won't accept other people's advice. You think it unwise to show yourself too openly in front of others. Sometimes you are outgoing and sociable, and sometimes you are introverted and cautious. Some of your ambitions are often unrealistic. Are you talking about yourself, haha?
