You’re standing in a crowded elevator. Everyone is facing the door. That’s the unspoken rule, right? But then, one person walks in and stands facing the back wall. They aren't saying anything. They aren't hurting anyone. Yet, you feel a weird prickle of discomfort. Your brain immediately flags this as weird. In sociology, that’s exactly where we start when asking what is a deviant behavior. It’s not always about crime or being "bad." Sometimes, it’s just about breaking the invisible scripts we all follow to keep society running smoothly.
Deviance is a slippery concept because it’s a moving target. What’s considered totally normal in a boardroom in Manhattan might be seen as an outrageous act of defiance in a rural village in the Himalayas. It’s less about the act itself and more about the audience. As Howard Becker, a heavy hitter in the world of sociology, famously argued in his 1963 book Outsiders, deviance isn't a quality of the act a person commits, but rather a consequence of the application by others of rules and sanctions to an "offender." Basically, you’re only deviant if society decides to point a finger at you.
The Spectrum: From Pink Hair to Bank Heists
We tend to lump everything "different" into one bucket, but that's a mistake. Scholars usually split this stuff into two camps: formal and informal deviance.
Formal deviance is the easy one. It’s crime. It’s when you break a law that’s actually written down in a book somewhere. If you rob a liquor store or cheat on your taxes, you’ve crossed a legal line. The state gets involved. There are handcuffs, fines, or maybe a jail cell. This is the stuff of police procedurals and true crime podcasts.
Informal deviance is way more interesting and happens every single day. This is about "folkways" and "mores"—those unwritten social expectations. Think about picking your nose in public, wearing a tuxedo to a backyard BBQ, or even just talking too loudly in a library. You won't get arrested, but you’ll definitely get "the look." That collective side-eye is society’s way of policing you. It’s a soft punishment designed to make you feel awkward enough to get back in line.
Why Do We Even Care What Is A Deviant Behavior?
It’s easy to think of deviance as a bug in the system. If everyone just followed the rules, everything would be perfect, right? Well, not exactly. Emile Durkheim, one of the founding fathers of sociology, actually argued that deviance is necessary for a healthy society. He believed that when someone breaks a rule, it forces the rest of us to come together and reaffirm what our values are.

When a community reacts to a "deviant," they are drawing a line in the sand. They are saying, "This is who we are, and that is what we are not." It creates social cohesion. Beyond that, deviance is often the engine of social change. Think about the Suffragettes or the Civil Rights Movement. At the time, Rosa Parks refusing to move to the back of the bus was legally and socially classified as deviant behavior. Today, we recognize it as a heroic act of justice. Without people willing to be "deviant," society would just stay stuck in the mud forever.
The Labeling Theory Trap
One of the most fascinating ways to look at this is through Labeling Theory. This theory suggests that people don't just "become" deviant—they are branded. Once someone is labeled as a "troublemaker" or a "criminal," society starts to treat them differently. They might find it harder to get a job or make friends. Eventually, that person might start to believe the label themselves.
It’s a self-fulfilling prophecy. This is why some activists and sociologists get so worried about how we treat "at-risk" youth. If you tell a kid they’re a deviant often enough, they’ll eventually stop trying to prove you wrong and just start leaning into the role.
Biology vs. Environment: Where Does It Come From?
For a long time, people thought you could spot a "deviant" just by looking at them. In the late 1800s, an Italian criminologist named Cesare Lombroso claimed that criminals were "evolutionary throwbacks." He thought big jaws and long arms were signs of a "born criminal." Honestly, it sounds ridiculous now, but people bought into it for years.
Modern science is a bit more nuanced. We know there might be some genetic predispositions—maybe some people are naturally more prone to risk-taking or have lower impulse control. But the environment usually pulls the trigger. Robert Merton’s "Strain Theory" explains this perfectly. Merton argued that society sets up goals (like the American Dream) but doesn't give everyone the same tools to reach them. When someone wants the nice house and the car but has no legal way to get them, they might turn to "innovative" deviance—like selling drugs or white-collar crime—to close the gap. It’s not that they’re "broken"; it’s that the system is rigged, and they’re trying to find a workaround.

The Power of Social Control
Why don't most of us just go wild? If I’m stuck in traffic, why don't I just drive on the sidewalk? Travis Hirschi’s Control Theory says it’s all about our bonds to society. He pointed out four main things that keep us behaving:
- Attachment: We don't want to disappoint people we care about, like our parents or partners.
- Commitment: We’ve invested too much in our "normal" lives. A high school teacher isn't going to shoplift because they’d lose their career.
- Involvement: If you’re busy working, playing sports, or volunteering, you literally don't have time to get into trouble.
- Belief: You actually believe that the rules are fair and right.
When these bonds weaken—if someone feels isolated, has nothing to lose, and doesn't believe in the system—that’s when you see an uptick in deviant acts. It's less about "bad people" and more about "broken connections."
Context Is Everything (The "Where" Matters)
You can't talk about deviance without talking about culture. Take tattoos, for example. Fifty years ago, if you had a full sleeve of ink, people might assume you’d been to prison or were part of a rough biker gang. It was a clear marker of deviance. Today? Your dental hygienist probably has a tattoo. Your accountant might have a piercing. The behavior hasn't changed—people are still putting ink in their skin—but the meaning of the behavior has shifted entirely.
The same goes for things like cannabis use. In many places, it’s gone from a "deviant" drug associated with counter-culture and crime to a legal product you buy at a store with a credit card. This shift is called "normalization." It happens when a deviant behavior becomes so common that the social stigma eventually just... evaporates.
The Dark Side of the Digital Age
The internet has changed the game for deviance. Before the web, if you had a really niche, deviant hobby or a strange belief, you were the "village oddball." You were isolated. Now, you can find a community of thousands of people who share that exact same deviance.

This has a double-edged effect. On one hand, it’s great for marginalized groups to find support. On the other hand, it allows for the "echo chamber" effect. People with extreme or harmful views can find validation online, making their deviant behavior feel "normal" within their specific bubble. Cyber-deviance, from hacking to online harassment, is a whole new frontier that sociologists are still trying to map out. It's much easier to break a rule when you're behind a screen and don't have to look your "victim" in the eye.
Real-World Examples You Might Not Have Considered
Think about "Positive Deviance." This is a concept used in international development and public health. It’s the idea that in every community, there are some people whose uncommon but successful behaviors enable them to find better solutions to problems than their neighbors who have access to the same resources.
A famous study in Vietnam looked at childhood malnutrition. Researchers found that even in the poorest villages, some kids were healthy. Why? Because their mothers were engaging in "deviant" feeding practices—like adding tiny shrimps and crabs from rice paddies to their food, or feeding them four times a day instead of two. These moms were breaking the local "norm" of how to feed a child, and in doing so, they saved their kids. This proves that being "deviant" isn't just about rebellion; it's often about survival and innovation.
Misconceptions to Toss Out
- Deviance = Mental Illness: While some people with mental health issues may act deviantly, the two are not the same. Most deviant acts are committed by people who are perfectly "sane" but have different values or goals.
- Deviance is always harmful: As we’ve seen, deviance can lead to social progress and better health outcomes.
- Only "bad" people are deviant: We are all deviant at some point. Ever gone 10 mph over the speed limit? Ever took a "sick day" when you weren't actually sick? Congrats, you’ve engaged in deviant behavior.
Moving Forward: How to Navigate Deviance
Understanding deviance isn't just a fun academic exercise. It’s a tool for empathy. When you see someone acting "weird" or breaking a norm, instead of immediately judging, try to look at the context. Ask yourself: What rule are they breaking? Why does that rule exist? Who does the rule benefit?
If you feel like you’re being labeled as "deviant" yourself, remember that labels are often more about the person doing the labeling than they are about you. Society loves boxes, but humans are messy.
Actionable Insights for Everyday Life
- Check your bias: Next time you feel that "elevator discomfort," pause. Is the person actually doing something harmful, or are they just breaking a script you’ve been taught to follow?
- Evaluate the "Why": If you’re struggling with a behavior that society deems deviant, look at Merton’s Strain Theory. Are you lacking the resources to meet a goal? Sometimes changing your environment or your goal is more effective than just trying to "be better."
- Support positive deviance: If you’re in a workplace or a community that’s stuck, look for the "positive deviants"—the people doing things differently and getting better results. Instead of pressuring them to conform, learn from them.
- Understand the power of the label: Be careful about the words you use to describe others, especially kids. Calling someone "bad" or "lazy" can stick in ways that are hard to un-stick later in life.
Deviance is simply the shadow cast by our social rules. You can't have one without the other. By understanding what is a deviant behavior, we get a clearer picture of the invisible walls we live inside—and we learn when it might actually be a good idea to kick one of them down.
