Friday the 13th: 13 superstitions explained
Superstitions are surprisingly widespread, including a fear of Friday the 13th and a belief in good-luck charms.

We humans are a superstitious lot, believing that Friday the 13th is bad luck and finding a penny is good luck.
Many superstitions stem from the same human trait that causes us to believe in monsters and ghosts: When our brains can't explain something, we make stuff up. In fact, a study last year found that superstitions can sometimes work, because believing in something can improve performance on a task.
Here, then, are 13 of the most common superstitions.
13. Beginner's luck
Usually grumbled by an expert who just lost a game to a novice, "beginner's luck" is the idea that newbies are unusually likely to win when they try a sport, game or activity for the first time.
Beginners might come out ahead in some cases because the novice is less stressed about winning. Too much anxiety, after all, can hamper performance. Or it could just be a statistical fluke, especially in chance-based gambling games.
Or, like many superstitions, a belief in beginner's luck might arise because of confirmation bias. Confirmation bias is a psychological phenomenon in which people are more likely to remember events that fit their worldview. If you believe you're going to win because you're a beginner, you're more likely to remember all the times you were right — and forget the times you ended up in last place.
12. Find a penny, pick it up …
And all day long, you'll have good luck. This little ditty may arise because finding money is lucky in and of itself. But it might also be a spin-off of another old rhyme, "See a pin, pick it up/ and all day long you'll have good luck/ See a pin, let it lay/ and your luck will pass away."
11. Don't walk under that ladder!
Frankly, this superstition is pretty practical. Who wants to be responsible for stumbling and knocking a carpenter off his perch? But one theory holds that this superstition arises from a Christian belief in the Holy Trinity: Since a ladder leaning against a wall forms a triangle, "breaking" that triangle was blasphemous.
Then again, another popular theory is that a fear of walking under a ladder has to do with its resemblance to medieval gallows. We're sticking with the safety-first explanation for this one.
10. Black cats crossing your path
As companion animals for humans for thousands of years, cats play all sorts of mythological roles. In ancient Egypt, cats were revered; today, Americans collectively keep more than 81 million cats as pets.
So why keep a black cat out of your path? Most likely, this superstition arises from old beliefs in witches and their animal familiars, which were often said to take the form of domestic animals like cats.
9. A rabbit's foot will bring you luck
Talismans and amulets are a time-honored way of fending off evil; consider the crosses and garlic that are supposed to keep vampires at bay. Rabbit feet as talismans may hark back to early Celtic tribes in Britain. They may also arise from hoodoo, a form of African-American folk magic and superstition that blends Native American, European and African tradition. [Rumor or Reality: The Creatures of Cryptozoology]
8. Bad luck comes in threes
Remember confirmation bias? The belief that bad luck comes in threes is a classic example. A couple things go wrong, and believers may start to look for the next bit of bad luck. A lost shoe might be forgotten one day, but seen as the third in a series of bad breaks the next.
7. Careful with that mirror
According to folklore, breaking a mirror is a surefire way to doom yourself to seven years of bad luck. The superstition seems to arise from the belief that mirrors don't just reflect your image; they hold bits of your soul. That belief led people in the old days of the American South to cover mirrors in a house when someone died, lest their soul be trapped inside.
Like the number three, the number seven is often associated with luck. Seven years is a long time to be unlucky, which may be why people have come up with counter-measures to free themselves after breaking a mirror. These include touching a piece of the broken mirror to a tombstone or grinding the mirror shards into powder.
Three sixes in a row give some people the chills. It's a superstition that harks back to the Bible. In the Book of Revelation, 666 is given as the number of the "beast," and is often interpreted as the mark of Satan and a sign of the end times.
According to State University of New York at Buffalo anthropologist Philips Stevens, the writer of Revelation was writing to persecuted Christians in code, so the numbers and names in the book are contemporary references. Three sixes in a row is probably the numeric equivalent of the Hebrew letters for the first-century Roman Emperor Nero.
5. Knock on wood
This phrase is almost like a verbal talisman, designed to ward off bad luck after tempting fate: "Breaking that mirror didn't bring me any trouble, knock on wood."
The fixation on wood may come from old myths about good spirits in trees or from an association with the Christian cross. Similar phrases abound in multiple languages, suggesting that the desire not to upset a spiteful universe is very common.
4. Make a wish on a wishbone
The tradition of turkey bone tug-of-war goes back a long way. Legend has it that first-century Romans used to fight over dried wishbones — which they believed were good luck — and would accidentally break them, ushering in the idea that whoever has the largest bit of bone gets their wish. Bird bones have also been used in divination throughout history, with a supposed soothsayer throwing the bones and reading their patterns to predict the future.
3. Cross your fingers
Those wishing for luck will often cross one finger over another, a gesture that's said to date back to early Christianity. The story goes that two people used to cross index fingers when making a wish, a symbol of support from a friend to the person making the wish. (Anything associated with the shape of the Christian cross was thought to be good luck.) The tradition gradually became something people could do on their own; these days, just saying "fingers crossed" is enough to get the message, well, across.
2. No umbrellas inside
… And not just because you'll poke someone's eye out. Opening an umbrella indoors is supposed to bring bad luck, though the origins of this belief are murky. Legends abound, from a story of an ancient Roman woman who happened to have opened her umbrella moments before her house collapsed, to the tale of a British prince who accepted two umbrellas from a visiting king and died within months. Like the "don't walk under a ladder" superstition, this seems to be a case of a myth arising to keep people from doing something that is slightly dangerous in the first place.
1. Friday the 13th
If you're not scared of Friday the 13th, you should be scared of the word used to describe those who are: friggatriskaidekaphobics. (An alternative, though just as tongue-twisty, word for the fear is "paraskevidekatriaphobia.")
For a superstition, the fear of Friday the 13th seems fairly new, dating back to the late 1800s. Friday has long been considered an unlucky day (according to Christian tradition, Jesus died on a Friday), and 13 has a long history as an unlucky number.
According to the Stress Management Center and Phobia Institute in North Carolina, about 17 million people fear Friday the 13th. Many may fall prey to the human mind's desire to associate thoughts and symbols with events.
"If anything bad happens to you on Friday the 13th, the two will be forever associated in your mind," said Thomas Gilovich, a psychologist at Cornell University. "All those uneventful days in which the 13th fell on a Friday will be ignored."
