The criteria for classification of a paranormal phenomenon

What criteria are used to evaluate the seriousness and reliability of a sighting

Jacques Vallee is a renowned researcher in the field dell'ufologia, in particular for having redefined a classification system for the phenomena ufologist and more generally paranormal experiences. This classification, called Vallee Classification , Became in time the most widely used Hynek system . The criteria for classification are 5: Level of consequences of the phenomenon (sigla AN ) behavior UF (acronym MA ), The presence, quantity and type of evidence of what (acronym FB ) And type of close encounter (acronym EC ) And a criterion of three numbers to judge 's reliability the alert (acronym SVP ).

Consequences of the phenomenon:

  • AN1 : There were anomalies without permanent effects (such as lights or unexplained explosions);
  • AN2 : There were anomalies with lasting effects (such as materialization and circles in the grain);
  • AN3 : There were anomalies with associated entities (ghosts, spirits, creatures legendary);
  • An4 There was an interaction with any entity associated with abnormalities (experience of almost-death, religious miracles and visions, OBE);
  • AN5 : Reports of damage or abnormal deaths (spontaneous human combustion, unexplained injuries);

Behavior underscores:

  • MA1 A UFO was observed to follow a trajectory discontinua;
  • MA2 How MA1 caused more from the physical effects;
  • MA3 As more entities MA1 on board underscores;
  • MA4 : UF maneuvers are accompanied by a feeling of transformation of reality by insurance;
  • MA5 : UF maneuvers have caused permanent damage or death, the observer;

Presence, quantity and type of evidence of what happened:

  • FB1 : A simple UFO sighting across the sky along a straight line;
  • FB2 How FB1 but with physical evidence;
  • FB3 : Sighting of a UFO on board which have been seen living entity;
  • FB4 : Sighting of a UFO with a feeling of transformation of reality by insurance;
  • FB5 A UFO sighting that causes permanent damage or death, the observer;

Type of close encounter:

  • CE1 : Contact with a UFO within 150 meters from the point of observation, no consequence for the witness;
  • CE2 How CE1 but leaves traces of land or tangible harm to the witness;
  • Ce3 Have been observed sull'UFO entities;
  • CE4 : Abduction of the witness;
  • CE5 How CE4 but with permanent damage or death to the witness;

For reliability is based on number format of three digits whose meaning is as follows.
First, reliability of the source:

  • 0: unknown or unreliable source;
  • 1: the source is unknown, but it was not possible to define un'attendibilità;
  • 2: reliable source of second-hand;
  • 3: reliable source of first hand;
  • 4: in person interview with a witness as a source of proven reliability;

Second, experience of those who visited the place of occurrence:

  • 0: no visit to the site;
  • 1: on-site visit by a person not familiar with the phenomenon in question;
  • 2: on-site visit by a person familiar with the phenomenon in question;
  • 3: on-site visit by an investigator with sufficient experience;
  • 4: on-site visit by an experienced analyst;

Three possible explanations:

  • 0: there are more natural explanations with data to support;
  • 1: Natural explanation requires only slight modifications of the data collected;
  • 2: Natural explanation requires major alteration of a parameter;
  • 3: natural explanations require a major alteration of several parameters;
  • 4: given the facts, there is no possible natural explanations;

For example the symbol MA1-301 (taken from a case reported by BUFORA for the British government) means that this is an observation of a UFO that follows a discontinuous path and that the source is reliable, first-hand, that there were on-site visits and natural explanations require slight modifications to the data collected.
