Quick Answer
Surprisingly, Friday the 13th often sees fewer insurance claims for accidents, fires, and thefts than other Fridays. This is due to superstition. People, subconsciously or consciously aware of the date's 'unlucky' reputation, tend to be extra careful, leading to a demonstrable dip in reported incidents. It's a fascinating example of how a widespread belief can actually influence behaviour and create a safer reality.

- 5Data shows lower rates of fire, theft, and traffic accidents on Friday the 13th compared to other Fridays.
- 6Collective superstition inadvertently creates a safer environment through mass psychological caution.
Why It Matters
It's surprising that the superstition surrounding Friday the 13th actually leads to fewer accidents due to people being extra cautious.
Friday the 13th is statistically safer than a typical Friday because the prevailing fear of bad luck leads people to behave with extreme caution, resulting in fewer accidents and insurance claims.
Summary
- The Dutch Centre for Insurance Statistics found fewer reports of fire, theft, and accidents on Friday the 13th compared to other Fridays.
- Psychologists attribute this to paraskevidekatriaphobia, a fear that drives people to stay home or drive more carefully.
- Financial markets and air travel often see lower volume, but not necessarily lower returns or safety risks.
- The superstition costs the US economy an estimated 800 million dollars in lost productivity each year.
Why It Matters
Understanding the Friday the 13th effect reveals how collective superstition can inadvertently create a safer physical environment through a mass shift in human psychology.

The Safety of Superstition
The fear of Friday the 13th is so pervasive it has its own clinical name: paraskevidekatriaphobia. While many dismiss it as a relic of medieval dread, the data suggests that this phobia acts as a strange sort of public safety announcement.
Researchers at the Dutch Centre for Insurance Statistics (CVS) analyzed data over a two-year period to see if the date actually correlated with disaster. The results were counterintuitive. On a typical Friday, the CVS recorded around 7,800 traffic accidents. On Fridays that fell on the 13th, that number dropped to roughly 7,500.
The same trend appeared in data regarding fires and thefts. Because people were primed to expect disaster, they took fewer risks. They checked their stoves twice, drove at lower speeds, or simply stayed off the roads entirely.
The Origin of the Dread
The marriage of Friday and the number 13 as a harbinger of doom is relatively modern, but its components are ancient. In Christian tradition, there were 13 guests at the Last Supper, and the Crucifixion occurred on a Friday. In Norse mythology, a dinner party for twelve gods was crashed by a 13th guest, Loki, leading to the death of Balder.
However, the specific dread of the date only solidified in the popular consciousness during the 19th and early 20th centuries. The publication of Thomas Lawson’s 1907 novel, Friday, the Thirteenth, played a significant role in cementing the date as a day of potential financial ruin.
Economic and Behavioral Shifts
While the physical world might be safer, the economy takes a hit. Donald Dossey, founder of the Stress Management Center and Phobia Institute, estimated that the US economy loses hundreds of millions of dollars every time the 13th falls on a Friday. This is not due to accidents, but to avoidant behavior. People cancel flights, postpone weddings, and delay major purchases or business contracts.
According to a study published in the American Journal of Psychiatry, there is no spike in psychiatric admissions on Friday the 13th, yet the psychological weight remains heavy enough to influence global travel patterns. Airlines often report a significant dip in bookings, and many hotels around the world still skip the 13th floor entirely to appease guests.
Real-World Applications
The Commuter Choice
If you are planning a road trip, Friday the 13th might actually be the most logical day to choose. With fewer drivers on the road and those who are present being more attentive to hazards, the statistical likelihood of a collision decreases.
Professional Bargain Hunting
The date is an ideal time for major life events that require bookings. High-end wedding venues, caterers, and photographers often have gaps in their calendars for these specific Fridays. Choosing the 13th can lead to significant discounts and better service due to the lack of competition for the date.
Financial Market Strategy
While the Lawson novel suggested market crashes, modern analysis shows that the stock market is largely indifferent to the calendar. Investors who remain rational can often find opportunities while others are distracted by perceived omens.
Is Friday the 13th the unluckiest day for everyone?
No. In many Spanish-speaking countries, Tuesday the 13th (Martes 13) is considered the day of misfortune. In Italy, Friday the 17th is viewed with similar suspicion.
Does the 13th floor exist in most buildings?
Structurally, yes, but many developers skip the number in the elevator panel and floor numbering. A survey by the Otis Elevator Company found that up to 85 percent of high-rise elevator panels omit the number 13.
How many Friday the 13ths happen in a year?
Every year has at least one Friday the 13th, and there can be up to three in a single calendar year. Any month that begins on a Sunday will contain a Friday the 13th.
Key Takeaways
- Safety through fear: The date is statistically safer for driving and home security because of increased human vigilance.
- Economic friction: Significant revenue is lost due to cancelled plans and travel anxiety.
- Cultural variation: The superstition is not universal; other cultures fear different number and day combinations.
- Rational advantage: Those who ignore the superstition can benefit from cheaper flights and easier bookings.
