Fuzzy effect-Barnum effect

It means that it is easy for us to believe a general and conceptual concept, and then apply it directly to ourselves and judge ourselves with the help of external information, even if the concept is very vague and unreasonable.

The concept of fuzzy effect is often something empty and irrelevant, but in reality it often plays a psychological, physical or chemical role, resulting in a more real and extensive phenomenon. Many social phenomena have the shadow of Barnum effect, such as fortune telling, such as astrology.
