Lourdes effectとは 意味・読み方・使い方

The term Lourdes effect has been coined by the Belgian philosopher and skeptic Etienne Vermeersch to account for the conjecure that some supernatural powers seem to have a sort of resistance to manifesting themselves in a completely unambiguous fashion. According to Vermeersch, should the miraculous power of Lourdes actually exist there would be no reason to think that it would be more difficult for the Virgin Mary or God to reattach a severed arm than to cure paralysis or blindness. According to Vermeersch, the visions and photos of, for instance, the Loch Ness Monster and the Yeti lack reliability and clarity due to a similar effect.
