Friday the 13th Superstitions List
The list of superstitions continued to grow as time elapsed, with some people adding new superstitions to the list and others following them blindly. The fact that these superstitions cost us in millions every year shows how deep-rooted they are in the society. That being said, given below is a list of Friday the 13th superstitions, some of which may take you by surprise.

An 'accident' is a broad concept which can include everything, ranging from a safety pin pricking your finger to a car accident, and this plays a crucial role when it comes to any superstitious belief - including the superstitions about Friday the 13th. Basically, the slightest bad thing that happens to you on Friday the 13th is bound to stay in your mind forever, even if it is just about forgetting your wallet at home or reaching office late - which must have happened on several occasions. As a non-believer, you might find all this funny, but that's how things work on this allegedly inauspicious day.

The morbid fear of Friday the 13th can be attributed to the concept of 'selective bias' in psychology, wherein one only takes into consideration the data which supports his statement - while ignoring the rest of the facts that don't support or contradict his belief. Many people, for instance, cite the Turkey earthquake which occurred on Friday the 13th March, 1992, when highlighting 'how unlucky this date is', but they ignore the fact that there have been earthquakes - a lot more disastrous than the Turkey earthquake, which neither occurred on Friday, nor on 13th of the month.

That was a brief account pertaining to the history and superstitions on Friday the 13th. Skeptics, in an attempt to eliminate these Friday the 13th superstitions from the society, have been intentionally scheduling the important events of their lives on this day. That though, has done very little good to this date which is more popular as the unluckiest day of the year. At the end of the day, these are just superstitions which are engraved on your mind, and only critical thinking can get rid of these and other such superstitions from our society. And getting rid of this irrational fear is the need of the hour considering that these superstitions are taking a toll on our productivity.

PS: That it can occur at least once, and at the most thrice, in a single year as per the Gregorian calendar, is one of the most interesting, but lesser known facts about Friday the 13th.
