Why do some people calculate the loss of goods so accurately?

Fortune tellers are actually using people's psychology, which is called Barnum effect. Generally, people who actively seek fortune-telling believe in fortune-telling, so when the fortune-telling results come out, regardless of whether the results are right or not, the psychology will subjectively believe them. If you count the lost things, it may be 10 times, 9 times wrong, but once it is right, but the person who successfully finds the lost things this time will believe the fortune teller's story and then promote it for him. The cause of Barnum effect is considered as subjective verification. Subjective verification can affect us, mainly because we want to trust our hearts. If we want to believe something, we can always collect evidence to support ourselves. Even if it doesn't matter, we can still find a logic and make it conform to our own ideas. In our hearts, the ego occupies most of the space, and everything about me is very important.
