Are there any evidence of psychic abilities?

The potential existence or absence of psychic abilities, also known as dogs, was scientifically examined by the US National Academy of Sciences for about 150 years (since 1858). In 1985, the organization issued a statement that came to the conclusion that there was "no scientific justification from research conducted for 130 years for the existence of parapsychological phenomena". According to the survey, only 2% of scientists at the National Academy of Sciences in Phenomena or Psychic Abilities believed.

According to parapsychologists, these scientists are closed and some phenomena dogs, including ESP (extrasensory perception) and psychokinesis have experimental support. Most scientists argue that any apparent experimental support for the existence of psychic abilities is either within what would be predicted (this accusation is particularly common when the size of the sample is low), it represents intentional fakers (Eitjeje experimenters or subjects),The existence of dogs. "Sender" versus random picture. This effect persisted, although conditions have been used that allegedly increased psychological abilities, such as the use of twins, siblings or spouses. Scientists called these experiments "the strongest evidence so far against the existence of paranormal mental phenomena".

One of the first and most popular tests for the presence of dog phenomena are famous zener cards, five cards with symbols: circle, cross, wavy lines, square, aa star. The experimenter goes through the deck of the cards, observes the result and (when hiding the card) asks an object to be a symbol on the other side. After many thousands of these experiments, participants rarely worked better than chances, and when a new experimental control was introduced, such as shuffling the card using a machine, performing more attempts and separating the participant and the experimenter by a greater distance, the effect disappeared.Karl Zenner has shown a bad understanding of statistics and scientific methods, such as interpretation of results worse than chances as indicating the presence of dog phenomena ("skipping dogs") and attributing convergence to random performance over time (which is to be expected unless real) if tests are required.

Since the brief revival of activities in the 1970s. almost all university departments practicing dog research was closed. Today, there are only two, the Department of Psychiatric Medicine of the University of Virginia and the Veritas University of New Mexico.
