Psychological line of fortune telling

A book on psychology says: "Smart people don't need fortune telling; Only those who have doubts can tell fortune. Fortune telling is all fake. The fortune teller says something, and the listener will say something. The more people listen, the greater the chance for fortune tellers to win. " The accurate general criticism is: "Your life, it is not easy for your mother to give birth to you, and life is nine times out of ten unsatisfactory!"

The netizen upstairs is right. Many psychology books are rubbish. Numerology should be the father of psychology.
