Why We Believe in Luck

Why We Believe in Luck

Good luck.

Bad luck.

A lucky break.

We talk about luck constantly. Finding a perfect parking spot, catching a green light, landing the right job at the right moment. But what do we actually mean when we say something was lucky?

In this episode of Curious by Design, we explore why humans believe in luck—and what’s really happening beneath that idea.

For most of history, people used luck to explain events that felt meaningful but unpredictable. Long before probability theory existed, luck helped fill the gap between randomness and understanding. Our brains are wired to search for patterns, even when none exist, which is why people develop lucky rituals, believe in streaks, and assume chance events should “balance out.”

We’ll explore the psychology behind these beliefs, from the illusion of control to the gambler’s fallacy, and why cultures around the world created symbols like four-leaf clovers and horseshoes to represent good fortune.

But the story of luck gets even more interesting. Research shows that people who believe they’re lucky often behave differently—they notice opportunities more often, take more risks, and stay optimistic after setbacks.

In other words, luck may not be a mysterious force controlling events.

But the belief in luck can still change how people act—and sometimes that makes all the difference.

Because what we call luck is often something else entirely:

chance meeting preparation.

That’s Curious by Design.

Welcome to Curious by Design. I'm your host, Jason Hardwick. This is the show about how things get built and why they end up the way they do. We tend to think design is about logos, architecture, or how something looks. But in reality, design is about choices. It's about trade-offs. It's about the invisible decisions that shape businesses, cities, systems, and even our everyday lives. On this podcast, we explore the thinking behind the work. How we got here, what worked, what didn't. All starting from the same place. Curiosity. A way to understand what's working, what's broken, and how we might design things better. If you've ever found yourself asking, why did they do that? You're in the right place. This is Curious by Design. Think about the last time you said the word luck. Maybe it was after finding a good parking spot, or catching a green light just before it turned red. Maybe it was something bigger. Landing a job, meeting the right person, avoiding a problem you never saw coming. We talk about luck all the time. Good luck, bad luck, lucky breaks, unlucky days. Entire lives are sometimes described as lucky or unlucky. But here's the strange thing. Luck is one of the most commonly used ideas in human language, and also one of the hardest to define. Because when we say something is luck, what we usually mean is something else entirely. We mean something happened that we didn't expect. Something that feels meaningful, but something we can't fully explain. And humans have always struggled with that space between randomness and meaning. The word luck itself has an interesting origin. It didn't appear in English until the late Middle Ages. It likely came from a Middle Dutch word, geluk, which meant happiness or good fortune. At the time, people didn't think of luck as random chance. They thought of it more like fate, a force that guided outcomes, something closer to destiny. If a harvest succeeded, that was luck. If it failed, that was luck too. Luck wasn't just coincidence. It was a way of explaining events that felt larger than human control. Before modern science and probability theory existed, luck filled an important gap. It gave people a framework for understanding uncertainty. And uncertainty has always been one of the most uncomfortable parts of being human. Our brains are designed to search for patterns. This ability helped humans survive. If early humans noticed that rustling grass sometimes meant a predator nearby, they survived longer. Recognizing patterns meant recognizing danger. But there's a side effect. Our brains often detect patterns even when none exist. Psychologists call this patternity, the tendency to see meaningful patterns in random events. It's the same reason people see shapes in clouds, or faces on the surface of the moon, or believe that wearing the same socks during a winning streak helps their team win. Our brains prefer patterns over randomness because randomness feels unsettling. This is why humans are so susceptible to something called the illusion of control. We like to believe we influence outcomes that are actually random. Gamblers are famous for this. Rolling dice harder when they want a higher number, softer when they want a lower one, blowing on dice for luck. None of these actions change the physics of the role, but they create a sense of participation, a sense of agency, which makes uncertainty feel less frightening. Casinos understand this psychology very well. Games are designed to reinforce the illusion that players influence outcomes. Slot machines include buttons. Dice are rolled by hand. Cards are physically handled. All of these elements make the player feel involved, even when the outcome is entirely determined by probability. Probability itself is actually a relatively new concept in human history. For most of civilization, people didn't have a mathematical way to describe chance. The first real studies of probability emerged in the sixteen hundreds. Mathematicians began analyzing games of chance. Dice, cards, lotteries, and they discovered something fascinating. Random events could be predicted over long periods of time. Not individually, but statistically. Flip a coin once, anything can happen. Flip it ten thousand times, and the results will almost always approach a perfect fifty-fifty split. What feels like luck in the short term often reveals predictable patterns in the long term. But human intuition doesn't naturally think this way. We're wired to focus on individual experiences, not statistical averages. So when someone wins the lottery, it feels extraordinary, even though millions of people were statistically guaranteed to lose. This disconnect between intuition and probability creates something psychologists call the gambler's fallacy. Imagine flipping a coin five times, and it lands heads every single time. Many people believe the next flip is more likely to be tails, because heads has already happened so many times. But that's not how probability works. Each coin flip is independent. The coin has no memory. Heads doesn't make tails more likely, and tails doesn't become overdue. Yet the human brain instinctively believes outcomes should balance out. This belief fuels gambling behavior, and it reinforces the idea that luck can shift, that a lucky streak can start, or an unlucky streak can end, even when the underlying probabilities remain exactly the same. Luck also shows up in the objects we associate with it. Many cultures have symbols meant to bring good fortune four leaf clovers, lucky coins, rabbits' feet, horseshoes hung above doorways. These objects aren't random, they come from specific historical beliefs. Take the four leaf clover. The plant Trifolium repens normally grows with three leaves. A fourth leaf is a genetic mutation. It occurs in roughly one out of every five thousand clovers, so finding one is genuinely rare, and rarity naturally feels special. Over time, rarity turned into symbolism. The four leaves were said to represent faith, hope, love, and luck. Horseshoes became lucky symbols in medieval Europe. Iron was believed to repel evil spirits, and the crescent shape resembled a protective symbol. People hung horseshoes above doors to guard homes from bad fortune. Whether the open end pointed up or down depended on the region. Some believed the horseshoe should hold luck inside. Others believed it should pour luck outward. The important thing wasn't the orientation, it was the belief that luck could be influenced. But interestingly, research suggests that people who believe in luck sometimes perform better in certain situations. Not because luck is real, but because belief affects behavior. Psychologist Richard Wiseman conducted studies comparing people who describe themselves as lucky versus unlucky. The results were surprising. Self-described lucky people tended to notice opportunities more often, take more social risks, remain optimistic after setbacks, and interpret ambiguous situations more positively. In other words, people who believed they were lucky behaved in ways that created more opportunities, which then reinforce the belief that they were lucky. Luck in this sense becomes partially self-fulfilling, not because chance changes, but because perception changes. There's also another psychological effect at work, something called survivorship bias. This happens when we focus on the visible winners and ignore the invisible majority who didn't succeed. Imagine hearing about a startup founder who dropped out of college and became a billionaire. It feels like luck. But we rarely hear about the thousands of people who took the same risk and failed, because their stories disappear from view. When only the winners are visible, luck starts to look more powerful than it actually is. And yet, luck does exist in one important way. Chance events really do influence outcomes. Where you're born, who you meet, the moment an opportunity appears. These things often lie outside personal control. But how people respond to those moments makes the difference. Two people can experience the same chance event. One might ignore it, the other might act on it. One sees coincidence, the other sees opportunity. From the outside, both outcomes look like luck. But inside the story, behavior often plays a much bigger role than chance. So why do humans believe in luck? Because it helps us navigate uncertainty. It gives language to events we can't predict. It softens the discomfort of randomness. And sometimes, believing in luck encourages behaviors that make positive outcomes more likely. Optimism, curiosity, a willingness to take chances. In that sense, luck may not be a force controlling the universe, but the belief in luck can still shape human behavior, which means it can shape outcomes too. The next time someone says they were lucky, it might be true in one sense. Chance played a role, but there's often more happening beneath the surface. Attention, perception, action, opportunity. Luck may feel mysterious, but often it's just probability meeting preparation. And that is curious by design. If something in this episode made you pause, rethink a decision, or see the world a little differently, that's the point. Design isn't just something we consume, it's something we participate in every day, whether we realize it or not.
