The SkepDoc, Harriet Hall, coined the phrase Tooth Fairy Science to refer to trying to find the cause or solution to a mystery without first ascertaining that the entity exists.
One could look at the demographics for how much money is given for lost choppers and whether race, religion, or riches play a role. You could look at trends of whether molars are deemed more valuable than incisors. And we could see if the pandemic impacted any of this. But all of this would be to assume the existence of a stealthy spirit who undertakes nocturnal sojourns to children who have one less tooth than they did the day before.
While no one seriously insists on the existence of a Tooth Fairy, they do so with Bigfoot, meridians, and extraterrestrial visitors. They ponder who may be Sasquatch’s closest biological relatives, wonder which internal bodily pathway should be punctured to cure eczema, and postulate as the purpose of alien anal probes. The do so without having first shown the relevant phenomena are real.
While Hall had medicine in mind, the concept of Tooth Fairy Science can also apply to history.
Consider the Holy Grail, which is purported to be the receptacle Jesus drank from during the Last Supper. It has been sought and written about for centuries.
However, there are no references to the Holy Grail in the Biblical accounts of Jesus, nor does the religious receptacle make so much as a cameo in any other first millennium text.
Writing for Skeptoid, Brian Dunning noted that 12th Century cleric Geoffrey of Monmouth published “History of the Kings of Britain,” which described Arthur as an unbeatable warrior and which included one of the first known references to the cup.
Then in 1190, Dunning continued, the poet Chrétien de Troyes created a heroic knight named Perceval, who proposes Arthur and his knights search for the Holy Grail in order to restore the assembly’s honor and prestige. Dunning noted that in this and future fictional works, the object was not near as important as the quest for it.
So it took nearly 1200 years for the notion of a Holy Grail to emerge. Since then, it has assumed iconic status and made countless appearances in print and film. According to Dunning, John Calvin identified nearly two dozen cups that had been identified by the bearer as the true Grail. Many other assertions have been made since, some of which ascribe supernatural powers to the cup, and none of which have cleared the first hurdle of proving that there had ever been a Grail held by a dining Jewish messiah.
