Why are people superstitious?

 Chardonnens says superstions belonging to magic category are exceedingly hermetical and ritualistic and its examples are witchcraft, potions, incantations, amulets etc. Chardonnens says Observation category needs an observer, divination category needs participant to tell what is to be observed, where as magic requires a participant who must follow a protocol to influence the future, and that these three types of superstition need increasing stages of participation and knowledge.
