Did you know that the fear of the number 13 is so widespread that it has a clinical name? It is called triskaidekaphobia.
All around the world, people actively try to dodge this seemingly ordinary number. You can see its influence everywhere—from elevators skipping floor 13 to hotels omitting the room number and airlines leaving out specific seating rows.
When Friday Meets the 13th
The superstition intensifies significantly when the 13th day of the month lands on a Friday. This specific phobia is known as paraskevidekatriaphobia.
Far from just being a quirky old myth, this fear has tangible, real-world economic impacts. Every single year, millions of people cancel travel plans, avoid booking flights, and postpone high-stakes business meetings to stay safe from perceived bad luck. Studies and market reports have shown that this mass avoidance costs the global economy millions of dollars in lost revenue.
Whether it is skipping a row in a conference room or altering vacation schedules, our society’s choices are surprisingly dictated by a two-digit number.
