Superstition can be described as the belief in supernatural forces, such as fate, to describe unpredictable factors. Psychologists found that superstition comes from the assumption that a connection exists between non-related events that coincide.

Individual beliefs and experiences drive superstitions, explaining why they are generally irrational.

• Some superstitious beliefs help promote a positive mental attitude, although they can lead to irrational decisions, such as trusting in good luck and destiny rather than sound decision making.
• Carrying charms, wearing certain clothes, preferring specific colours, and using particular numbers are elements of superstition.
• Superstitions can also give rise to the idea that objects and places are cursed. Many buildings do not have a 13th floor. In some countries, such as Italy and Brazil, the typical unlucky number is 17.
