Before an assumption can become a fact, it must be well supported with a set of reliable evidences. For an evidence to be considered reliable, it should undergo scientific methods first. In short, a fact is a product of a systematic research.
Psychic is one of the subjects of research studies that draws a lot of attention. This shows the apparent interest of most people in things that can't be easily explained by Science. Although there has been a significant increase of information that could prove the existence of metaphysical forces, the people involved in psychic research still find it hard to pull a plausible conclusion out of these. Various professors from different Ivy League universities have tried to come up with concrete explanations, but the truth is still far from reach. The most noted pioneer of psychic research is J. B. Rhine, an expert in the field of Parapsychology from Duke University who conducted his research way back in 1920s.
However, this doesn't mean that efforts on psychic research have been futile. They, of course, have managed to turn over theories that are helpful for future researchers. Every result produced by the studies acts like a piece of puzzle. People who want to learn more about should read about psychic research conducted in the past. Dr. Gertrude Schmeidler's "Sheep-and-Goat Effect" is a good starting point. The result of this particular study shows that non-believers of psychic forces such as ESP and Telekinesis are less likely to have those powers.
