If you’ve ever tossed a coin, you’re familiar with the phrase “heads or tails.” It’s an iconic term that has its roots in ancient history.
Learn more about this phrase and why it was invented in the first place!
History of the Coin Toss
Tossing a coin to determine an outcome has been around for centuries. The first recorded coin toss was in the Roman Empire.
The Romans used a coin called a “dupondius,” and its face was stamped with either two heads or two tails. “cavum” meant head, while “caput” meant tail.
The rules for coin tossing in the Roman Empire differed; one of the challengers would be assigned the “heads” side of the coin.
It was believed that whenever the coin landed on the “heads” side, the emperor agreed with that person because the emperor was on the heads side of the coin, and the tails side always lost.
Why Heads or Tails?
Since the Roman empire, the term heads or tails has been acknowledged by civilizations.
Heads always refer to the front side of the coin, which features a portrait or a head, and the tails refer to the opposite side.
It has been used as far back as ancient Greece, where it was said that King Midas would use a “magic” coin when he needed to make important decisions.
For example, if he had a difficult choice between two options—which road to take home from battle—he would flip the coin and see what side was facing up when it landed on the ground.
If his opponent won with heads and he lost with tails, then Midas knew that this was not an auspicious day for him and chose another path home instead!
How Does Coin Toss Usually Work?
Most people are familiar with the essential way coin tosses work: a coin is flipped in the air, then lands on one side or the other.
The side it lands on is called the “heads,” while the other is called “tails.”
Is it Reliable?
Let’s now look at some of how it’s unreliable.
- The coin is not weighted. This means that the coin was not specifically designed to land on one side or another more often than the other. While this does not make it impossible for a coin toss to result in “heads” every time, it makes it less likely—and makes you question why everyone would think this is how things work!
- The coin is not biased (biased). A biased object has been purposefully made to favor one side over another; for instance, if you were playing football with a ball and wanted your team to win every game, you could put extra weight on one side of it so that when thrown downfield toward someone from your team (who would hopefully catch), they would have more chance than usual of catching and returning towards their goal line (or perhaps even into their opponent’s end zone). This would give them an advantage over their opponents if done correctly—but luckily, our standardized coins aren’t purpose-built like this! That being said.
- The coin may have been damaged in some way, such as being bent or broken off at an angle, because these factors can affect its ability to land correctly on either end every time they’re flipped into midair while spinning around randomly through space before falling back down again after being tossed into the atmosphere by hand.
Before you go…
We can only say for sure if coin tosses are genuinely reliable. However, we know people have used them throughout history to decide something. And while they may not always be right, they seem pretty accurate most of the time. It’s not just luck, either! There are some things you can do before tossing a coin that will ensure it lands on its side more often than others (like using heavier coins).
