Superstition is the belief in supernatural causality—that one event causes another without any natural process linking the two events—such as astrology, religion, omens, witchcraft, and prophecies, that contradicts natural science.The word superstition is sometimes used to refer to religious practices (e.g., Voodoo) other than the one prevailing in a given society (e.g. Christianity in Western culture), although the prevailing religion may contain just as many superstitious beliefs.
