In parapsychology paranormal phenomena indicating knowledge of the events in the future, which can not be inferred from the current state of knowledge (which distinguishes them from predicting or forecasting), a concept closely related to clairvoyance.
Like all psychic matters, precognition is a controversial issue and is often objectionable to the scientific community, and even doubts among those involved in parapsychology. Question the existence of this phenomenon, as well as accuracy, or interpretation of the experiences of precognition.
Here's the position of parapsychology, which does not agree with most scientists.
Parapsychology phenomenon of precognition is divided into two levels:
personal - linked to the future of a particular person
ponadosobisty - on social phenomena, political, economic, natural, etc.
In addition, the ability of precognition is divided into:
immediate - ie, involving the ability to predict events that will occur in a very short time (few seconds)
distant in time - ie, involving the ability to predict events distant in time (eg the forthcoming year.)
The question of the existence of people with the ability of precognition is very controversial from a scientific point of view. While there are many historical and contemporary relationships of people who have had "visions" of future events, all of them are post-factum, and as such can not be regarded as convincing evidence for the existence of this phenomenon.
Founded in the UK and the U.S. Central Premonitions Registry is an institution dedicated to the collection of alleged or real vision for the future. The institution has existed since 1966. However, so far not been able to obtain a description of clairvoyance before the incident that actually took place later, as described clairvoyant person. There are numerous accounts only post factum - and the testimonies of witnesses (usually close friends and family members) claiming that he told his clairvoyant visions before the event actually took place.
Easier to scientific validation is the ability to anticipate events that take place in the near future. Many people in their everyday life is sometimes the impression that "knows" what was about to happen, but it is difficult to determine here is whether this "knowledge" comes from the ability to instantly, but the rational prediction what will happen, or whether it comes from "direct" contact with the not too distant future. The study deals with this phenomenon on a large scale such as Anomalous Princeton Engineering Research Center, which was founded in 1979 and has since carried out a one thousand various tests designed to examine this phenomenon. Many of the results of these experiments seems to confirm that in some situations, people tend to have an instant vision of the near future, which can not be rationally explained, but these results are still highly controversial and still debated in the literature.
