Have you heard of "mob mentality?" Most people might know the phrase but don't know that there's a generally regarded psychological term for it: deindividuation. The term is used by many to refer to how people in a group can lose their sense of identity, possibly causing them to behave in ways they normally wouldn't as a result.

Often, it can result in “innocent” crowd-oriented behavior—but not always. The more serious results of deindividuation can include codependency and the development of anxiety disorders. 

Deindividuation can be a serious and dangerous issue. Read on to learn more about the condition and possible supportive strategies that can help. 

What is deindividuation?

Your identity is generally a core part of who you are. It can include your self-awareness, your thoughts, beliefs, and behaviors. Self-awareness, in this context, is defined as being aware of yourself in relation to your standards. It may involve knowing your character, your morals, and your desires—all of which can be significant factors to consider as you continue to define your personhood. 

What is deindividuation? Definition

Deindividuation generally refers to an occurrence in which a person becomes part of a crowd or group and begins to lose their individual identity as a result. They might become less aware of themselves and who they are.

The more the person becomes involved in the group, the less self-awareness they may have, which includes a possible loss of ownership and awareness of their morals, character and beliefs. These qualities, then, might start to be replaced by the identity of the group. The individual may then begin to take on the morals and character that are held by the group as a whole, for better or for worse. 

What is deindividuation? Example

Think of being surrounded by fans at your favorite team's home game. Everybody is likely yelling, some people might be thumping their chests, and you might find yourself jumping up and down. You might not exhibit these behaviors if you were standing there by yourself. However, being a part of the crowd might carry you away from your personal identity, possibly leaving you to feel free to do things you normally wouldn't.

In some cases—like the game scenario above—acting differently in a group is not necessarily a “bad” thing, as long as you are able to remain aware of your own core values and beliefs. But in other instances, deindividuation can be harmful.

Examples of the negative effects of deindividuation

Classic examples of deindividuation can include the formation and operation of gangs, cults and large mobs of people who are unified by a governing set of beliefs or a code of conduct. The military is also generally thought to use elements of deindividuation as part of its training regimen, encouraging unified movement and thought. 

There are several examples of research that has been done regarding deindividuation and group dynamics. For example: In 1971, a psychologist by the name of Philip Zimbardo had been documented conducting an experiment to test the impact of deindividuation. 

In 1971, psychologist Philip Zimbardo conducted an experiment to test the impact of deindividuation. He split up a group of male students from Stanford University. Half of them were to act as prisoners and the other half were to behave as guards. The experiment was to last for two weeks, and everyone was told to play the role in their assigned group. 

However, the time frame had to be cut short and the experiment stopped after only six days. The guards had ended up grouping up—which resulted in many of them treating the prisoners so badly that they could not continue with the activities. This study on group dynamics became known to many as the Stanford Prison Experiment

We also can see group dynamics shift in many historic examples of mass looting after traumatic weather events. Take, for example, the time period immediately after Hurricane Katrina hit Louisiana. The devastation shut down the city and mass looting followed. The looting was not simply restricted to essential survival supplies Many videos from helicopters captured images of people walking out of stores carrying televisions and other electronic devices.

People weren’t just looting essential supplies either; many videos from helicopters were able to capture images of people walking out of stores carrying televisions, tech, and just about everything else you can think of. 

Many people might agree that most people wouldn't normally engage in such activity in their own individual sphere of existence, but during this crisis, it became a common event. This behavior shift may have occurred because people didn't feel they would be held responsible for their actions, so they crossed a line they might not have otherwise to satisfy their own motives or needs.

Why does deindividuation occur?

While there are some positive situations that can come as a result of deindividuation, it can often be dangerous for those who are affected. This causes many to ask the question: Why do people engage in behavior that they might know is wrong? The following are potential reasons:

Anonymity

When acting as a crowd, people might believe that they are anonymous, which can give them a sense of invisibility to act in ways they might not normally behave.

People might loosen their self-restraint in a group setting. They might develop a crowd mentality, which can prompt many to begin to act in the way the crowd is acting. In this context, people may not choose to focus on the morality of a given situation. Rather, they might begin to adopt the behaviors and attitudes of the groups that they are with—a phenomenon called groupthink—regardless of whether they align with one’s personal morals. 

Lack of accountability

There might be an attitude of diffused responsibility in a group setting. When acting as a group, people might believe that responsibility is spread out among others, possibly empowering them to take behavioral risks if they don’t believe that they will be personally at fault. This mentality can also encourage them to take less responsibility for their own actions, especially if they don’t believe that the consequences will be as drastic.

How to reduce deindividuation effects

Separate yourself from deindividuation effects

The first step for many when it comes to reducing deindividuation is to help people be (and remain) self-aware. If you are going somewhere with a large group of people, for example, you might take a moment and think through what your morals and values are. It can be helpful to know what you stand for and where the line is that you might be unwilling to cross. 

If you are in a situation and feel yourself starting to get caught up in the energy of the crowd, you might consider removing yourself from the situation before you start to experience a change in your behavior. You can also remind yourself that you can be responsible for your behavior, regardless of how many other people are doing the same thing. 

Focus on individual behavior

If you are trying to help reduce the effects of deindividuation in your life (or someone else’s), a helpful first step can be encouraging focus on individual identity. 

You can look for helpful self-awareness strategies. If you are hoping to prevent deindividuation in another person, you can talk to that person about their specific activities, possibly focusing on the impact of their actions on other people. 

Discuss the effects of deindividuation with someone who understands social psychology

If you believe you're experiencing the effects of deindividuation, working one-on-one with a therapist can help you get to a place where you have more self-awareness—possibly helping you to discover who you are. A therapist can also help you to forgive yourself and take the correct steps to move forward from any past problematic behaviors that might have been a result of deindividuation.

How can online therapy support people experiencing deindividuation?

If you or someone you know is working through the effects of deindividuation, it can be important to seek the help of a trusted professional. However, this process may be easier said than done, as the very prospect of outside support can feel overwhelming at times. BetterHelp offers convenient availability to online therapists who are ready to help you regain your awareness of self and keep control of it, even when in a large crowd.

Is online therapy effective?

Online therapy has become increasingly popular across many social groups over the last few years, but researchers have been gauging its effectiveness for some time. Veterans are one of the most common study populations for online therapy, many of whom may have been specifically seeking support for deindividuation and its effects. 

The New York Times recently ran an article about online therapy and cited two different studies where veterans were split into two groups, one who attended traditional in-person therapy, and one who attended online therapy. Both studies found information that suggests that both types of therapy are equally effective.

Takeaway

Knowing who you are and what matters to you can be important concepts to keep in mind as you work to avoid the dangers of deindividuation. Therapy can be a helpful tool to possibly assist you in establishing your sense of self-awareness. BetterHelp can connect you with an online therapist in your area of need.
