There is a character who is abnormally ready to think and act according to practice based upon trust in luck or other irrational, unscientific, or supernatural forces.

Notes:
This theme is primarily used with respect to common and classical superstitions, such as fortune telling. It is not used, for example, with respect to beliefs that were considered scientific, or even pseudo-scientific, in the context of the story.

Examples:
In tz1959e2x07 "Nick of Time", we saw that William Shatner (as Don) was quick to fall victim to the soothsayings of an infernal fortune telling machine, and learned that he had both a four-leaf clover and a rabit's foot, quite sincerely for good luck.
