The science of superstition – and why people believe in the unbelievable

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.
