13 Global Superstitions That Actually Make Sense

Superstitions exist in every culture, shaping beliefs, traditions, and behaviors. While some seem illogical or amusing, many global superstitions have surprising roots in science, psychology, or historical events.

From avoiding broken mirrors to fearing unlucky numbers, superstitions often stem from practical wisdom, ancient observations, or cultural practices that made sense in their original contexts. Whether designed to prevent misfortune, ensure prosperity, or protect against the unknown, these beliefs have stood the test of time.

In this article, we explore 13 global superstitions that, despite their mystical origins, actually make sense when examined through science and history.

1. Knocking on Wood for Good Luck (Worldwide)

Knocking on wood is a common superstition meant to prevent bad luck or invite good fortune. Its origins date back to ancient tree worship, where people believed spirits resided in trees. By knocking on wood, they sought the spirits’ protection.

From a psychological standpoint, this act also provides a sense of control over uncertain situations, making it a comforting habit.

2. Walking Under a Ladder Brings Bad Luck (Western Europe)

This superstition has both religious and practical origins. In Christianity, the triangle formed by a ladder leaning against a wall symbolizes the Holy Trinity, and disturbing it was considered blasphemous.

From a safety perspective, walking under a ladder is genuinely risky. Objects or the ladder itself can fall, making the superstition a practical warning.

3. Breaking a Mirror Brings Seven Years of Bad Luck (Ancient Rome)

The belief that broken mirrors bring bad luck originated in Ancient Rome, where mirrors were thought to reflect a person’s soul. Damaging a mirror meant damaging one’s spirit, and Romans believed the soul regenerated every seven years.

While there’s no scientific basis for soul damage, breaking a mirror often led to financial loss in ancient times, as mirrors were expensive. This superstition likely discouraged careless handling.

4. The Evil Eye Can Curse You (Middle East, Mediterranean, South Asia)

The Evil Eye superstition suggests that a person can curse another simply by looking at them with envy or malice. Many cultures use charms or amulets (like the Nazar eye) to ward off negative energy.

Psychologically, the belief in the Evil Eye may stem from social anxieties and the power of suggestion—people may subconsciously act differently when they feel watched or envied.

5. Friday the 13th is an Unlucky Day (Western Cultures)

The fear of Friday the 13th combines Christianity and numerology. The number 13 was considered unlucky because Judas, the betrayer of Jesus, was the 13th guest at the Last Supper. Additionally, Friday was the day of Jesus’ crucifixion, reinforcing the association with misfortune.

Psychologists argue that this superstition creates self-fulfilling prophecy effects, where people experience more misfortune simply because they expect it.

6. Sweeping Over Someone’s Feet Brings Bad Luck (Latin America, Italy, Turkey)

In some cultures, sweeping over someone’s feet is said to doom them to a life without marriage. This belief originated when sweeping symbolized removing fortune or opportunities, discouraging careless cleaning around people.

From a cultural perspective, this superstition may have been a way to teach respect and etiquette, ensuring people were mindful of others while cleaning.

7. Opening an Umbrella Indoors Brings Misfortune (Victorian England)

The superstition against opening umbrellas indoors began in Victorian England, when early umbrellas had metal spokes and springs that could easily injure people or break objects indoors.

This belief made practical sense, as accidents were common, and the superstition helped enforce safer behavior.

8. Whistling Indoors Attracts Bad Spirits (Russia, Korea, Japan)

In several cultures, whistling indoors is believed to invite bad luck or evil spirits. This belief likely emerged because, in the past, whistling was associated with calling supernatural entities or unsettling spirits.

Another practical explanation is that whistling at night could attract thieves or unwanted attention, making it a discouraged habit in many societies.

9. Tucking a Coin in a New Wallet or Purse Brings Wealth (China, Italy, Philippines)

Many cultures believe that gifting a wallet or purse should always include a coin or small amount of money to ensure financial prosperity.

This superstition likely originated from symbolic wealth attraction, reinforcing the idea that starting with money invites more financial success. It also aligns with psychological priming, where people who start with money tend to be more financially mindful.

10. Covering Mirrors During Mourning (Jewish and Chinese Traditions)

Some traditions involve covering mirrors after a death in the household to prevent spirits from becoming trapped.

While this belief has spiritual roots, it also serves a psychological function, helping mourners focus on grief instead of their reflections. The practice may also stem from avoiding distressing hallucinations during emotional mourning periods.

11. Leaving Shoes Upside Down Brings Bad Luck (Brazil, Middle East, India)

In many cultures, flipping shoes upside down is believed to invite misfortune or death into the household.

While this might seem purely superstitious, it also has a practical aspect. Flipped shoes often get dirtier, and discouraging this behavior helps maintain cleanliness in homes.

12. Itchy Palms Predict Money Gains or Losses (Caribbean, Europe, Africa)

One widespread belief states that an itchy right palm means incoming wealth, while an itchy left palm signals financial loss.

This superstition may have stemmed from associations between hands and financial exchanges. Historically, hands were used for bargaining and trade, making them symbols of economic luck.

13. Eating Grapes at Midnight on New Year’s Eve Brings Good Luck (Spain, Latin America)

In Spain and Latin American countries, eating 12 grapes at midnight on New Year’s Eve is believed to bring prosperity for the upcoming year. Each grape represents one month of good fortune.

This tradition has a practical origin: Spanish grape farmers promoted the custom in the early 20th century to encourage grape sales.

However, it also serves as a festive ritual that strengthens social connections and creates a positive mindset for the new year.
