If you go back to Palladium Games' Beyond the Supernatural, you run into a class called the nega-psychic. Psychic theory in Palladium games is that everybody has some psychic power, and most of us use it in mundane ways. Those with a great deal of it channel it into the ways of their unconscious desires. Thus, one psychic might become a "sensitive" (telepath/empath), where another might become a physical psychic (TK and pyrogenesis, etc.)

A nega-psychic is a psychically talented individual that doesn't believe in all this bullshit. Thus, his own psychic abilities conspire to prove him right. Without thinking that he is a psychic (because he doesn't believe that they exist), he is constantly using his psychic abilities to counter any other psychic or magical abilities going on around him.
