Telepathy is not the ability to "read" someones mind, it is the ability to communicate mental thoughts and to receive mental thoughts silently and with complete understanding.
Under the radar, I have been tested many times by the type of people identified in your referenced article but they were under the impression that a telepath has the ability to read someones mind. That is not how it works. Telepathy is just like speaking but you use your mind, not your mouth. It takes two people to communicate telepathecally, one to send and one to receive.
When I am in large crowds, I receive messages from some people, but I am sure that they are unaware that they are transmitting their thoughts. Much of what I have received has been gibberish but occasionally I receive coherent thought. Fitz, I believe that what you have experienced may have been telepathy. I would encourage you to work with whomever you may have these experiences.
Someday, in the future, all mankind will be telepathic and the world will never be the same. But if you want to see real changes to man's society, wait till they discover time travel.
