Paranormal is a general term (coined ca. 1915–1920) that designates experiences that lie outside “the range of normal experience or scientific explanation” or that indicates phenomena understood to be outside of science’s current ability to explain or measure. Paranormal phenomena are distinct from certain hypothetical entities, such as dark matter and dark energy, only insofar as paranormal phenomena are inconsistent with the world as already understood through empirical observation coupled with scientific methodology.
Thousands of stories relating to paranormal phenomena are found in popular culture, folklore, and the recollections of individual subjects. In contrast, the scientific community, as referenced in statements made by organizations such as the United States National Science Foundation, maintains that scientific evidence does not support a variety of beliefs that have been characterized as paranormal.
Notable paranormal beliefs include those that pertain to ghosts, extraterrestrial life and unidentified flying objects, and cryptids.
