Every week, people walk into our studios carrying ideas about self-defense that could get them hurt, arrested, or both. These beliefs get repeated so often that they start to sound like truth. Some come from outdated advice, some from social media, and some from shortcuts that feel good and fail under pressure. Hollywood created its own set of myths, which I cover separately in The Biggest Self-Defense Myths Movies Created. This article focuses on the beliefs I hear from real students on the training floor, especially the ones about decision-making, force, and the law.
The gap between what people believe and what actually works can decide whether someone walks away from a bad situation. Each myth below is followed by what I teach instead.
Myth: “All I Need Is One Thing”
People love the idea of a single answer. A gun, a knife, pepper spray, a groin kick, or an eye gouge. Someone will always argue that their choice solves every problem. Self-defense lives in context: who is in front of you, where you are, what led to the moment, who is watching, what the law allows, and what you are actually willing to do when the person is someone you know. A plan that depends on one tool is a bet. What works is a range of options, from awareness and distance to verbal boundaries and physical skills, and the judgment to choose between them.
Myth: “If I Don’t Fight Back, I’ll Be Safe”
This belief survives because it is sometimes true. In a robbery, handing over a wallet often ends the encounter, and that is usually the right choice. A large portion of violence is emotional, predatory, or explosive, and it has no negotiation phase. Once someone is actively assaulting you, passivity stops being a strategy, and the choice narrows to fighting back or accepting the risk of serious injury. The skill is recognizing which situation you are in, and training helps you make that call quickly.
Myth: “Self-Defense Is a Collection of Techniques”
Many people think self-defense means memorizing moves: block here, twist the wrist, escape the grab. That belief usually comes from programs that teach movements without context. Most real-world self-defense happens before anything physical starts, through awareness, distance, positioning, boundaries, voice, and leaving early. Physical skills matter, and they work best when they are the last layer of a plan that started much earlier. Techniques without judgment are choreography.
Myth: “If You Know Martial Arts, You Know Self-Defense”
Martial arts build skill, coordination, discipline, and conditioning. Self-defense deals with uncertainty, fear, legality, and unfair situations. I have seen skilled fighters make terrible decisions because they were never trained to think beyond a controlled environment. Some escalated when they should have walked away, and some hesitated when they needed to act. Knowing how to hit is different from knowing when, why, and how far to go. We explore this in Self-Defense Training vs Fighting.
Myth: “If I Feel Threatened, I Can Use Any Force I Want”
This belief ruins lives. Feeling threatened is not the legal standard. In most places, the use of force is judged by whether it was necessary, whether the threat was imminent, and whether your response was proportional. Fear and anger do not change those standards. The rules also vary by state, and New York has its own requirements for when force and deadly force are justified. I explain them in plain language in Self-Defense Law in NYC: When Force Is Legal. I am not a lawyer, and anyone who carries a weapon or wants certainty about their rights should consult one.
Myth: “A Warning Shot or Showing My Weapon Is a Safe Middle Step”
Pulling out a weapon to scare someone feels like a compromise. In many places, brandishing is a crime, and warning shots are both reckless and illegal. The law generally does not recognize symbolic force. If the situation does not justify using a weapon, it usually does not justify displaying one either.
Myth: “I’m the Good Guy, So I Won’t Get Arrested”
Police arrive after the fact. They were not there. They look at injuries, witnesses, video, and behavior, and they cannot see your intentions. Even justified self-defense can lead to arrest, charges, or a civil lawsuit. Knowing this changes how you act before, during, and after an incident: you avoid fights you could leave, you stop when the threat stops, and you are careful about what you say afterward. The question of who strikes first is especially misunderstood, and I address it in Can You Legally Hit First in Self-Defense?
Myth: “Prevention Means Blaming the Victim”
Violence is always the responsibility of the person who commits it. That truth does not change when someone teaches awareness. Rejecting prevention does not protect anyone. Awareness, boundaries, and preparation reduce opportunity for people who look for easy targets, and they do not create guilt. Refusing to use them simply leaves more power with those who exploit distraction.
Myth: “I Know Them. They Would Never Hurt Me”
A large share of violence against women, children, and older adults is committed by someone the victim knows. Familiarity lowers defenses and creates blind spots. Training that focuses only on stranger danger ignores where much of the harm actually comes from. Boundaries matter with friends, family, partners, and authority figures, and warning signs deserve attention regardless of who shows them. Our article on warning signs and red flags for sexual violence covers these behaviors in detail.
Myth: “Screaming Will Save Me”
Screaming can help in crowded places by drawing attention. In isolated places it may do nothing, and under stress many people cannot scream at all. A loud, clear command such as “Back off” can set a boundary and alert witnesses, and it works best alongside movement and action rather than in place of them.
Myth: “Training Makes Me Invincible”
Training improves your odds and gives you more options and better judgment. It does not guarantee outcomes. In a real encounter, the goal is to disrupt the attacker enough to disengage and escape. Clean technique helps, improvisation also works, and the body does not care how polished the solution looked. Students who understand this train harder and take fewer unnecessary risks.
Myth: “Always Retreat” and Other Absolute Rules
Distance can save lives, especially against blades and blunt weapons. Running blindly from a firearm at close range can be dangerous, and in a robbery, throwing down valuables and leaving may end things fastest. Retreat is a tactic that works when it creates safety. The same applies to other absolute rules people repeat: never grapple with a knife attacker, always back away, just block, make eye contact, hold keys between your fingers. Each of these can be useful in one context and harmful in another. Knife attacks close distance fast, blocking without countering fails, pain is unreliable under adrenaline, and backing away is slower than forward pressure. Awareness adapts to the situation. Rigid rules do not.
What Replaces These Myths
People want certainty, and violence does not offer it. Self-defense is the ability to think under stress, recognize danger early, respond proportionally, and live with the consequences of your actions. That ability is built through realistic training that includes decision-making and legal awareness alongside physical skills. Training does not make people violent. It makes them harder to manipulate, harder to surprise, and harder to break. If you want to build those skills with honest instruction, you can start with our self-defense classes in NYC.

One Response
The screaming myth deserves more space. Many people can’t produce a loud voice under stress, so a command like “Back off” has to be practiced out loud, repeatedly, before it shows up when it’s needed. That makes voice work a training item in its own right.
