Text: My roommate JS’s grandmother believes that left-handed people are evil. JS himself is left-handed.
Context: Told to me by JS one evening in our apartment. His grandmother’s family is from Texas, and the belief came down through her own family’s Catholic-inflected Mexican folk tradition. JS describes the belief as something his grandmother says with a considerable degree of humor, often teasingly, often when the topic of left-handed people comes up. They laugh together about the contradiction between the stated belief and his own existence as her left-handed grandchild.
Analysis: What is interesting about JS’s case is that the belief is doing none of the work it was originally meant to do, and yet it still circulates, just in a different way. She says it teasingly, often when JS is in the room, and the two of them laugh about the obvious contradiction between the rule she is pretending to hold and the left-handed grandson she is pretending to call evil. The belief has been domesticated into a running family joke. The “left as evil” belief is one of the most widely distributed folk beliefs in the world, showing up in Latin Catholic, Chinese, Islamic, and Hindu traditions with varying degrees of severity. The Latin American Catholic version draws on the Latin sinister (left meaning unlucky in Roman augury), the goats placed on the left at final judgment in the bible, associations of the left hand with the devil’s preferred side. What JS and his grandmother share is the belief’s late life: a folk rule that has lost its teeth, but is yet useful, here as the setup of a joke that grandmother and grandson perform together.
