Psychics have an amazing gift that gives them an advantage over other people. They use this upper-hand to get good jobs. They gravitate towards the intelligence community. Many in the C.I.A., for example, are psychic.
The reason most people don’t know about psychics is because real psychics don’t want you to know. If you knew that someone was psychic, you might not trust them.
Besides, many psychics believe that you should only talk about psychic things with other psychics. There are some things a person will only tell you telepathically. With that said, psychics are usually pretty honest telepathically. They will tell you exactly how they think they rule the world.
