Case Credibility Rating System
★★★★★ Very Low
★★★★★ Low
★★★★★ Moderate
★★★★★ High
★★★★★ Exceptional
Primarily anecdotal, anonymous or unverifiable witnesses, story surfaced long afterward, little/no contemporary documentation, serious inconsistencies, or evidence of fabrication.
Identifiable witness or source, but evidence is weak. Limited corroboration, secondhand reporting, questionable documentation, or plausible conventional explanations significantly weaken the case.
Credible identifiable witnesses and reasonable documentation. Some independent corroboration may exist, but important uncertainties remain or conventional explanations cannot be confidently excluded.
Multiple credible or independent witnesses, strong contemporary documentation, and/or supporting photographic, radar, physical, military, police, or scientific evidence. Conventional explanations have been investigated but remain inadequate or disputed.
Exceptionally well-documented case involving multiple independent sources and several mutually supporting forms of evidence. Records have strong provenance, major details are independently corroborated, and extensive investigation has failed to produce a convincing conventional explanation.
Close Encounters of the 6th Kind
A Close Encounter of the Sixth Kind (CE6) is defined in ufology as an encounter with an unidentified flying object or its occupants that results in the death of a human or animal. While not part of J. Allen Hynek's original 1972 scale, this classification has been adopted to describe severe, fatal incidents linked to UFO sightings.
Key Aspects of the Sixth Kind (CE6):
-
Definition: The fatal outcome (death) of a human or animal associated with a UFO.
-
Severity: This category is considered a more severe form of interaction than lower-level sightings.
-
Distinctions: Some classifications may also refer to this kind as involving the death of an alien entity, or sometimes, it is conflated with paranormal entities rather than extraterrestrials.
An expansion to the classification created by astronomer Dr. J. Allen Hynek, a technical advisor on UFO studies, to categorize experiences by increasing closeness.
