There's a [dead] reply taking me to task on my use of the word "superstition" because apparently Wikipedia thinks that superstitions have to be beliefs in the supernatural. Like all semantic arguments, this is boring and dumb, but in point of fact, the first definition in every dictionary I can find supports my usage.
Here's Random House:
a belief or notion, not based on reason or knowledge, in or of the ominous significance of a particular thing, circumstance, occurrence, proceeding, or the like.
