Shoehorning is a ploy used by psychics, or religiousapologetic or other charlatans, as a way to make it sound like their prophecies or those of earlier prophets had come true. The word is derived from shoehorn, a smooth curved implement, often of plastic or metal, inserted at the heel to help put on a shoe. In a similar fashion, shoehorning involves taking an earlier prophecy and attempting to affix a current event to it, with the event apparently "fulfilling" the prophecy, even though this has been realized after the fact. Shoehorned prophecies usually take vague prophecies and twist them to "mean" the event in question even if the evidence for the connection is shaky. Also, many psychics, such as James van Praagh, are accused of stating after the fact that they had predicted the event, even if evidence proves otherwise, also being an example of retroactive clairvoyance.
