Retrocognition

Retrocognition (also known as postcognition or hindsight ), from the Latin ''retro'' meaning "backward, behind" and ''cognition'' meaning "knowing", describes "knowledge of a past event which could not have been learned or inferred by normal means". The term was coined by Frederic W. H. Myers.

Overview

Retrocognition has long been held by scientific researchers into psychic phenomena to be untestable, given that, in order to verify that an accurate retrocognitive experience has occurred, it is necessary to consult existing documents and human knowledge, the existence of which permits some contemporary basis of the knowledge to be raised.

For instance, if you purport retrocognitive knowledge that "Winston Churchill killed a parrot", the only way of verifying that knowledge would be to consult extant sources of Churchill's activities. If it is found that he did, indeed, kill a parrot at one time, it could be said that you "simply" obtained contemporary knowledge of this fact (by clairvoyance or telepathy, if need be, of the relevant documents or someone's knowledge of them), rather than directly perceived – in the manner of retrocognition – any event in Churchill's past. Given this fundamental logical difficulty, there has been very little experimental investigation by parapsychologists of retrocognition. The evidence for retrocognition has, therefore, been limited to naturalistic cases suggestive of the phenomenon.

The most popularly celebrated case of retrocognition concerns the visions in 1901 of Annie Moberly and Eleanor Jourdain – two scholars and early administrators of British university education for women – as they tried to find their way to Marie Antoinette's private château, the Petit Trianon. Becoming lost on their way, they believed that they instead came unto the Queen's presence itself. They published an account of their experience in 1911 as ''An Adventure''. Moberly and Jourdain described how they had become convinced, over the following weeks, that persons they saw and even spoke to on that occasion – given certain details of dress, accent, topography and architecture – must have been of a presumed ''recollection'' by Marie Antoinette, on 10 August 1792, of her last days at Trianon in 1789. While often considered in popular literature as evidence for retrocognition, the book was immediately dismissed by Eleanor Sidgwick, a leading member of the British Society for Psychical Research, in an article published in its ''Proceedings'', as the product of mutual confabulation.Iremonger, L.
