Certain beliefs among the members of society sometimes arise out of fear, sometimes from helplessness, and sometimes by chance. These are generally referred to as "superstitions." These beliefs have existed since the earliest days of mankind. Many of them have no scientific basis and are not linked to any particular religious belief. Although they often appear illogical or unreasonable, they are still an integral part of people's hearts, brains, and minds. In the emergence of such beliefs, people's psychological make-up, the words of the, often illiterate, elderly as well as those of religious officials have all played a role. These beliefs have even revealed differences between individuals, yet they all have certain aspects in common.
