The siren song of significance

How is statistical analysis like the Odyssey? Here’s an analogy that I used in my research methods course last semester to explain the purpose of study pre-registration. If you’ve ever read the Odyssey, you’ll recall the story of the Sirens, the enchanting lady-monsters whose singing lures to certain death any sailor who hears them. (See Wikipedia for crib notes.) On the advise of his witch-friend Circe, Odysseus pulls a stunt so that he can hear the song of the Sirens while still making it safely past.
