Experts described Triskaidekaphobia as a psychology problem. The fear goes beyond rationality, it occurs without a consideration of normal sense. People who have Triskaidekaphobia just believe that they have to fear the Friday the 13th. No rational explanation can convinced them that it only happened on their mind. Their belief can be compared to religious people who believe in whatever they believe.
Donald Dossey, a historian and author of "Holiday Folklore, Phobias and Fun," estimates 17 million to 21 million people in the United States are affected with Triskaidekaphobia. These people won't fly or go about normal business in this particular day, resulting in an estimated $800 million to $900 million of loss in business.
The fear of Friday the 13th has go further. People with Triskaidekaphobia are worried with anything that has number 13 on it. Even with super-advanced technology, many skyscrapers still don't have 13th floors, an example of how superstition can easily defeat technology. Realtors might not care about Friday the 13th, but their Triskaidekaphobia buyers still shows reluctance to look at a house with number 13 in the address.
Science has proven that Friday the 13th is no more dangerous than any other day of the year. It's just another Friday, nothing more. Feeling something bad might happened on Friday the 13th? Statistics from The Dutch Centre for Insurance Statistics shows that fewer accidents and reports of fire and theft occurred on Friday the 13th. This is because people are going more careful or just stay home. Driving is also slightly safer on Friday the 13th, because everyone is too afraid to drive recklessly, or maybe even reluctant to drive at all.
So, Friday the 13th should be a day where something bad is unlikely to happened. As conclusion, it's the best day of the year.
