Bahrain effect: why is the blood group constellation accurate?

In real life, some people like fortune telling, while others like to study horoscopes and blood types. And more or less found that what they said was quite accurate. In fact, it is from the psychological "Bahrain effect" to explain why some horoscopes or zodiac books can "accurately" point out someone's personality. Do you want to know why? People often think that a generalization and general description of personality reveals their own characteristics very accurately, which is called "Barnum effect" in psychology. Barnum Effect, also known as Balin Effect, is named after a popular and famous magician, Shoman barnum. He once said in his evaluation of his performance: His program is popular because it contains elements that everyone likes, so people are cheated every minute. For example, Aquarius is rational, loves freedom, and Cancer is emotional and caring. However, cancer people will never be rational, and Aquarius people will lack love? We don't deny the value of the constellation, after all, it has statistical basis. But if you want to be a smart person and not superstitious about constellations, I have to tell you that you are wrong again! Do you know what it means to be drunk even if you are drunk? Since more than half of the people around you believe in horoscopes, why are you trying to overthrow the ideas rooted in your heart (in fact, this is impossible)? If a couple are not very compatible in astrology, even if they are not superstitious, they will inevitably bear great psychological pressure. In the future communication time, if there is conflict and friction, the existing "really inappropriate" preset will be forcibly established, and eventually it is inevitable to break up! In daily life, we can't always reflect on ourselves, nor can we always observe ourselves as an outsider, so we can only know ourselves with the help of external information. Because of this, when everyone knows himself, it is easy to be hinted by external information, get lost in the environment, be hinted by the surrounding information, and take other people's words and deeds as a reference for their actions. "Know yourself when you succeed and know your friends when you fail" certainly has some truth, but in the final analysis, we all know ourselves. Regardless of success or failure, we must adhere to the dialectical point of view, not ignore the strengths and advantages, but also recognize the shortcomings and deficiencies.
