25 Most Popular Superstitions Around The World
Superstitions are one of humanity’s most universal traits. No matter where you live, what language you speak, or what century you were born in, the odds are good that you’ve knocked on wood, avoided a black cat, or tossed a coin into a fountain hoping for a little cosmic help. These rituals and beliefs — rooted in folklore, religion, and cultural memory — have survived thousands of years of scientific progress and still shape how billions of people think and act today.
What makes superstitions so fascinating is that they reveal something deeply human: our need to find patterns, create meaning, and feel some degree of control over an unpredictable world. From ancient Rome to modern Seoul, the 25 most popular superstitions around the world tell a story not just about fear and luck, but about culture, history, and the quirks of human psychology.
Whether you’re a true believer or a skeptic who secretly still picks up a penny from the sidewalk, this guide takes you on a global tour of the superstitions that have captured our collective imagination — where they come from, what they mean, and why they refuse to die.
The Psychology Behind Superstitions
Before diving into the list, it helps to understand why superstitions exist at all. Psychologists point to a phenomenon called illusory correlation — the human brain’s tendency to link two unrelated events simply because they happened close together in time. Break a mirror, then stub your toe an hour later? Your brain files that as cause and effect.
Superstitions also thrive because they offer comfort. When life feels chaotic and uncontrollable, rituals — even irrational ones — provide a sense of agency. Research from the University of Cologne found that participants who were given a “lucky charm” actually performed better on skill-based tasks, suggesting that belief itself can generate measurable psychological benefits.
Cultural transmission plays a huge role too. Children absorb the superstitions of their parents and communities long before they develop the critical thinking skills to question them. By the time they do, the beliefs are already woven into identity and tradition — and that’s a powerful thread to cut.

Superstitions of Good Fortune and Prosperity
1. Knocking on Wood (Global)
Origin: Pagan Europe | Luck: Good
This might be the single most widely practiced superstition on Earth. The act of knocking on wood after making a hopeful or boastful statement is believed to ward off bad luck. The most commonly cited origin traces back to pagan beliefs that trees were inhabited by spirits — touching wood would either invoke their protection or prevent them from hearing your boast. A secondary theory connects it to the Christian tradition of touching the wooden cross for divine protection.
2. Finding a Four-Leaf Clover (Western Cultures)
Origin: Celtic Europe | Luck: Good
The four-leaf clover is rare — only about 1 in 10,000 clovers has four leaves — and that rarity is exactly the point. In Celtic tradition, each leaf represented something: faith, hope, love, and luck. The Druids believed four-leaf clovers allowed them to see evil spirits and thus avoid them. Finding one still carries an unmistakable thrill, even for the most rational among us.
3. Rabbit’s Foot (Various Western Cultures)
Origin: Ancient Europe and Africa | Luck: Good
Carrying a rabbit’s foot for good luck is a practice that spans multiple continents and centuries. Rabbits were associated with fertility and prosperity, and specifically, the left hind foot of a rabbit caught in a cemetery was believed to carry protective power. The superstition traveled to North America through African American folk magic traditions known as hoodoo, where it became one of the most recognized lucky charms in popular culture.
4. Lucky Penny (North America and Europe)
Origin: Ancient beliefs in metal’s divine properties | Luck: Good
“Find a penny, pick it up, all day long you’ll have good luck.” This simple rhyme reflects an ancient belief that metal — forged from the earth and shaped by human hands — was a gift from the gods. Finding a coin face-up was especially auspicious. The luck allegedly doubles if you pass the penny on to someone else rather than keeping it for yourself.
5. Throwing Salt Over Your Shoulder (Global)
Origin: Ancient Rome and Europe | Luck: Averts bad luck
Salt was extraordinarily valuable in the ancient world — Roman soldiers were partly paid in salt, which is where the word “salary” comes from. Spilling it was both economically wasteful and spiritually dangerous. The belief held that the devil lurked over your left shoulder, ready to exploit misfortune. Throwing a pinch of spilled salt over that shoulder would blind him temporarily, averting disaster.
6. Breaking a Wishbone (Western Cultures)
Origin: Ancient Rome | Luck: Good (for the winner)
The tradition of two people pulling apart a dried chicken or turkey wishbone dates back to the Etruscans and was later adopted by the Romans, who would make wishes on fowl bones. The person who ends up with the longer piece after the break gets their wish granted. Today, it’s most closely associated with Thanksgiving in the United States, though the tradition is widespread across the English-speaking world.
7. Lucky Number 7 (Global)
Origin: Ancient religious and mystical traditions | Luck: Good
Seven shows up everywhere: seven days of the week, seven deadly sins, seven notes on the musical scale, seven wonders of the ancient world. In many religious traditions, seven is divine — God rested on the seventh day, there are seven heavens in Islamic tradition, and seven is central to numerous spiritual texts. This cross-cultural significance has cemented its reputation as the luckiest number in the world.
8. New Year’s Eve Grapes (Spain)
Origin: Alicante, Spain, circa 1909 | Luck: Good
In Spain, the clock strikes midnight on New Year’s Eve and people race to eat 12 grapes — one for each bell toll — representing 12 months of prosperity. The tradition is believed to have originated in 1909 when Alicante grape growers, sitting on a surplus harvest, promoted the custom to boost sales. Over a century later, it’s one of Spain’s most beloved national traditions, complete with grape-eating competitions and pre-portioned grape packages sold in supermarkets.
9. Elephant Statues Facing the Door (India and Southeast Asia)
Origin: Hindu tradition | Luck: Good
In Hindu tradition, the elephant-headed god Ganesha is the remover of obstacles and the bringer of prosperity. Placing elephant statues at the entrance of a home with their trunks raised and facing the door is believed to invite good fortune inside. If the trunk points downward, the luck stays contained and stable — different positions carry different meanings across various regional traditions.
10. Beginner’s Luck (Global)
Origin: Psychological observation | Luck: Good
This universal belief holds that people new to an activity have an inexplicably higher chance of succeeding. While statistically questionable, psychologists suggest that beginners’ lack of anxiety and overthinking actually does give them an edge in certain skill-based activities. The expectation of good fortune also creates a relaxed mental state conducive to performance — making this superstition arguably one of the most self-fulfilling on the list.

Superstitions of Caution and Misfortune
11. Black Cats Crossing Your Path (Western Cultures)
Origin: Medieval Europe | Luck: Bad (in some cultures, good in others)
Few superstitions are as internationally recognized — or as culturally inconsistent — as the black cat. In medieval Europe, black cats were associated with witchcraft and were believed to be familiars of witches or even witches in disguise. In the United States and much of continental Europe, a black cat crossing your path still signals bad luck. Ironically, in the United Kingdom and Japan, black cats are considered good luck — a reminder that superstitions are entirely in the eye of the beholder.
12. Breaking a Mirror (Global)
Origin: Ancient Rome | Luck: 7 years of bad luck
Ancient Romans believed that mirrors held a fragment of the observer’s soul, and that breaking one would damage that soul. They also believed the soul renewed itself every seven years — hence the duration of the curse. The seven-year period may also have practical roots: mirrors were expensive and incredibly difficult to replace in the ancient world, so the superstition may have encouraged careful handling of valuable household objects.
13. Walking Under a Ladder (Global)
Origin: Ancient Egypt and medieval Christianity | Luck: Bad
A ladder leaning against a wall creates a triangle — a shape the ancient Egyptians considered sacred. Walking through that triangle was seen as desecrating holy space. Medieval Christianity reinforced this: the triangle represented the Holy Trinity, and passing through it was blasphemous. There’s also a practical theory — ladders were commonly used to carry coffins and later set up at gallows — making walking beneath one a grim symbolic act.
14. Friday the 13th (Western Cultures)
Origin: Christian tradition | Luck: Bad
The fear of Friday the 13th is so widespread it has its own clinical name: paraskevidekatriaphobia. Both components carry independent bad luck: Friday was traditionally associated with the crucifixion of Jesus, and 13 is linked to the 13 people present at the Last Supper — including Judas, who betrayed Christ. The combination of the two into a single dreaded day is a relatively modern cultural construction, popularized in the 20th century through films and media.
15. Opening an Umbrella Indoors (Western Cultures)
Origin: Ancient Egypt | Luck: Bad
Ancient Egyptians used canopied umbrellas as sacred shields against the sun — a symbol of the sky deity. Opening one indoors was an insult to the sun god and an invitation for divine wrath. A more practical Victorian-era explanation also exists: spring-loaded umbrellas were notorious for popping open violently, and doing so indoors risked injuring people or damaging fragile household items. The superstition may have begun as a safety rule dressed up in spiritual clothing.
16. Spilling Salt (Global)
Origin: Ancient civilizations worldwide | Luck: Bad
Salt was used as currency, as a preservative, and as a sacred purifying agent across ancient Rome, Egypt, and the Middle East. Spilling it was a serious offense — both economically and spiritually. The belief that spilled salt invites evil is so persistent that Leonardo da Vinci depicted a spilled salt shaker next to Judas in his famous painting The Last Supper. Of course, the remedy is simple: throw a pinch over your left shoulder.
17. Unlucky Number 13 (Western Cultures)
Origin: Norse mythology and Christianity | Luck: Bad
The number 13 carries such cultural weight that architects routinely skip the 13th floor in building designs, airlines omit row 13, and entire cities report measurable drops in economic activity on Friday the 13th. In Norse mythology, Loki was the uninvited 13th guest at a dinner party who caused chaos and death. Combined with its Christian associations, 13 became the most feared number in the Western world.
18. Unlucky Number 4 (East Asian Cultures)
Origin: Linguistic coincidence in Chinese | Luck: Bad
What 13 is to the West, 4 is to East Asia. In Mandarin Chinese, the word for “four” (sì) sounds nearly identical to the word for “death” (sǐ). The same linguistic overlap exists in Japanese (shi) and Korean (sa). The result is tetraphobia — the widespread avoidance of the number 4. In Hong Kong, South Korea, and parts of China, buildings routinely skip floor numbers containing 4, and products with a “4” in the price point or model number can see dramatically lower sales.
19. Birds as Omens (Various Cultures)
Origin: Ancient divination practices worldwide | Luck: Often bad
Birds have served as omens across virtually every human civilization. A bird flying into your house is considered an omen of death in many European and Native American traditions. An owl hooting during the day is a bad omen in much of Africa and South America. In ancient Rome, the direction and species of birds in flight were formally studied by priests called augurs, and military campaigns were launched or abandoned based on their findings.
20. Whistling Indoors (Russia and Nordic Countries)
Origin: Slavic and Norse folklore | Luck: Bad
In Russia, whistling indoors is believed to whistle away your money — a superstition so embedded in daily life that many Russians visibly wince when someone does it. Nordic traditions carry a similar warning, with whistling indoors thought to summon wind spirits or evil entities. Sailors across northern Europe extended this to ships: whistling onboard was thought to provoke storms by “calling the wind.”
21. Placing Shoes on a Table (UK and Ireland)
Origin: British tradition | Luck: Bad
Putting shoes on a table is one of the most persistent and specifically British superstitions. The most widely accepted origin connects it to the practice of placing the shoes of a deceased miner on the table to announce his death to the household. Another theory links it to the tradition of new shoes being hung from a gallows after a hanging. Either way, shoes on the table remain a quick way to make a British grandmother deeply uncomfortable.
22. Not Cutting Nails at Night (India and Turkey)
Origin: Practical and spiritual traditions | Luck: Bad
Before electric lighting, cutting nails at night was genuinely risky — a nick in the dark could lead to infection. But the superstition evolved well beyond practicality. In Hindu tradition, cutting nails after dark invites negative energy and displeases Lakshmi, the goddess of wealth. In Turkey, the same act is said to invite the devil or cause a death in the family. The practical origins have been completely eclipsed by spiritual ones.
23. Chewing Gum at Night (Turkey)
Origin: Turkish folklore | Luck: Bad
One of the more unsettling entries on this list, Turkish folklore holds that chewing gum after dark is the equivalent of chewing on the flesh of the dead. The exact historical root of this belief is murky, but it persists widely enough that many Turks — particularly older generations — genuinely refuse to chew gum after sunset. It’s a vivid example of how a superstition’s persistence has almost nothing to do with its plausibility.
24. Pointing at a Rainbow (Philippines)
Origin: Filipino folk tradition | Luck: Bad
In Filipino folklore, pointing directly at a rainbow will cause your finger to rot, become deformed, or fall off entirely. The belief likely stems from the idea that rainbows are sacred natural phenomena — divine bridges between worlds — and that pointing at them is a form of disrespect that invites physical punishment. Children across the Philippines are routinely warned against it, and many adults still curl their fingers when gesturing toward one.
25. Fan Death (South Korea)
Origin: Modern South Korean culture | Luck: Fatal
Perhaps the most uniquely modern superstition on this list, fan death is the widespread South Korean belief that sleeping in a sealed room with an electric fan running can cause suffocation or hypothermia — and death. Despite being completely debunked by science (electric fans don’t remove oxygen from a room), this belief has been so persistent that South Korean fan manufacturers used to include safety warnings on their products, and Korean news outlets have reported “fan death” as a cause of death for decades. It’s a remarkable case study in how modern superstitions can form and calcify in a single generation.

FAQ
What is the most common superstition in the world?
Knocking on wood is widely considered the most universally practiced superstition, recognized and performed across dozens of cultures on every inhabited continent.
Why do people still believe in superstitions despite scientific evidence?
Superstitions persist because they serve psychological functions: they reduce anxiety, provide a sense of control, and are deeply embedded in cultural identity. Even people who intellectually reject them often practice them out of habit or cultural loyalty.
Are any superstitions considered good luck in some cultures but bad luck in others?
Absolutely. The black cat is the most famous example — it’s a bad omen in the United States and much of Europe, but considered good luck in the UK and Japan. Similarly, the number 4 is unlucky in East Asia but carries no negative meaning in the West.
What is the fear of Friday the 13th called?
The clinical name is paraskevidekatriaphobia — derived from Greek words for “Friday,” “thirteen,” and “fear.” While few people suffer it severely enough to qualify as a phobia, millions worldwide do modify their behavior on this day.
Is fan death a real danger?
No. There is no scientific evidence that sleeping in a room with an electric fan can cause death. The belief is specific to South Korea and has been thoroughly debunked by medical experts, yet continues to persist culturally.
Which continent has the most unique superstitions?
Every continent has rich superstition traditions, but Asia — spanning East Asia, South Asia, and Southeast Asia — arguably offers the widest variety due to its linguistic diversity, ancient religious traditions, and population size.
