What is Paraskavedekatriaphobia?

Paraskavedekatriaphobia is the abnormal and irrational fear of Friday the 13th. The origins of the superstitions surrounding the number 13 bleed over into any application, such as fearing the 13th floor, but the real origins of the superstition are not clear.
According to the Stress Management Center and Phobia Institute in North Carolina, as many as 21 million people in the U.S. suffer from this fear to a notable degree. The Phobia Institute has also estimated that as much as $900 million are lost in business annually due to avoidance of Friday the 13th.

The term paraskavedekatriaphobia is derived from the Greek words “paraskevi” and “dekatries” which mean “Friday” and “13” respectively.

Causes of Paraskavedekatriaphobia

Paraskavedekatriaphobia is a specific (or “isolated”) phobia, centered on non-social key factors. Isolated phobias tend to have some previous trauma (often in childhood and often physically injurious) as a root cause; a fear of bees may stem from an injury in childhood, for instance.

Upbringing can also play a role, such as parental warnings about a direct threat (such as “snakes can bite and kill you”) which is especially notable in cases where a threat is more imminent. (An allergy to bees or peanut butter, for instance, would naturally reinforce a real medical concern.)

It is thought that genetics and hereditary factors may play a role in specific phobias, especially those related to a danger of injury. (A primal “fight or flight” reflex may be more easily triggered in those with a genetic predisposition, for instance.)

By contrast, social phobias (like a fear of body odor or touch) are less well understood, are driven by social anxiety and are broadly labeled as “social anxiety disorder”.

In all kinds of phobias, external experiences and / or reports can further reinforce or develop the fear, such as seeing a family member or friend who is affected. In extreme cases, indirect exposures can be as remote as overhearing a reference in conversation or seeing something on the news or on TV and movies.

Paraskavedekatriaphobia, like most phobias, stems from a subconscious overprotection mechanism, and as with many phobias can also be rooted in an unresolved emotional conflict.
