10 Defense Mechanisms of the Self. With Examples

Defense mechanisms are one of those concepts in psychology that often generate a lot of interest, both professionally and in coffee conversations. These psychological strategies are essentially the tricks our mind employs to protect us from thoughts or feelings that might be disturbing or threatening. These are not simple mental traps, but complex processes that help us manage anxiety, stress and overwhelming emotions. Defense mechanisms operate at an unconscious level, which means that we are often unaware that we are using them.

When talking about defense mechanisms, we are obliged to talk about Sigmund Freud, the father of psychoanalysis, who introduced this concept, although it was his daughter Anna Freud who really delved into the study of the defense mechanisms of the self. Anna not only focused on the theoretical aspects, but also provided a more applied dimension, classifying these mechanisms in a way that facilitated clinical analysis and therapeutic intervention.

Understanding defense mechanisms is not just an academic exercise or an intellectual curiosity. It is fundamental for any psychological therapy, as it offers us a window into how people manage their discomfort, conflicts and traumas. Moreover, it is an indispensable tool for psychotherapy, whatever the theoretical approach, because ultimately we are dealing with the defenses that each individual has built throughout his or her life.

We are going to go deeper into some of the different protection or defense mechanisms that our mind uses according to the proposals of Freud and his daughter Anna, giving some examples of each mechanism so that you can understand them more easily (or even realize if you are using them and did not know)


This is one of the best known defense mechanisms and, in fact, it was Freud who really put this concept on the map of psychology. Repression is basically like the self’s personal security service. When there are thoughts, memories or desires that are too threatening or disturbing to handle, the self represses them, sending them into the unconscious. It is not that they disappear, they are simply stored in a kind of emotional safe, far from consciousness.

But here comes the part that interests us: although repressed, these elements do not stop influencing our behavior. They can manifest themselves in indirect ways, such as dreams, forgetfulness, or even physical symptoms. It is as if these repressed thoughts were ghosts haunting a house, invisible but definitely making their presence felt.

Classic example: Imagine that as a child you had a traumatic experience with a dog. You might repress the memory to avoid the discomfort it causes. However, you might develop an unexplained phobia of dogs, without remembering why you feel that way. In this case, repression acts as a protection, allowing you to function without being constantly distressed by the traumatic memory. But it also comes at a cost, in the form of phobia.

So what is to be done about repression? In therapy, one of the goals might be to bring those repressed thoughts or memories out into the open so that you can address them in a healthier way. It’s not an easy process, but it’s a way to take power away from those ghosts and allow you to live in a more authentic and less limited way.


If repression is sending your thoughts or emotions to an unconscious“basement,” displacement is more like relocating them to a different “room.” In other words, you take the emotional energy or impulse you feel toward a person or situation and redirect it to something or someone less threatening.

Here’s the key: the original target of the impulse may be something that poses a threat to your emotional well-being or even your physical integrity. Therefore, displacement functions as an escape mechanism, allowing you to release tension without facing direct negative consequences. However, like other defense mechanisms, displacement has its dark side; you may end up damaging relationships or aspects of your life that actually have nothing to do with the original problem.

A classic example is the employee who is having a bad day at work, perhaps because his boss yelled at him or because he is under a lot of stress. Instead of dealing with the situation, which could have risks such as losing his job or worsening working relationships, this employee comes home and takes out his frustration on his family or pet. Here, the employee is displacing his anger onto a “safer” target, but in doing so he is also polluting his home environment with negative emotions.

Therapy can help you identify and manage these displacement patterns, allowing you to more directly confront the emotions and situations that trigger them. In doing so, you not only lessen the emotional burden on other aspects of your life, but you also more effectively address the root causes of the problem. As always, self-knowledge is key to uncovering these intricate emotional landscapes.


Have you ever had that thing happen to you where you clearly see a flaw or problem in someone else, but then realize that you are describing exactly what you don’t like about yourself? That’s projection at its finest. Projection is like an emotional mirror that deflects attention away from your own insecurities or flaws by reflecting them onto someone else. In short, you attribute your own qualities, especially the less attractive ones, to other people.

The irony of projection is that often people who do this are completely convinced that the problem really lies with the other person. For example, imagine feeling insecure about your own level of intelligence or knowledge in a study group or at work. Instead of facing and working on your own insecurities, you might start criticizing the intelligence of your peers or colleagues, claiming that they are the ones who really don’t understand what is going on.

Another classic example is the couple where one partner is attracted to another person outside of the relationship. Instead of facing this feeling and understanding what it means, he or she might accuse his or her partner of being unfaithful or intending to be unfaithful. It’s like saying,“It’s not me, it’s you.” But in reality, the initial problem is with the person projecting those feelings.

And while we’re on the subject of relationships, there are also cases where the projection involves positive qualities. For example, you might idealize someone by attributing to them characteristics that you wish for yourself. In this case, projection becomes a way of avoiding the task of developing those qualities in yourself.

Although projection can offer temporary relief from difficult emotions, it often complicates things further in the long run, sometimes becoming very destructive. Therapy can help dismantle these projective patterns, allowing for a clearer understanding of both self and relationships with others.


This is the total refusal to accept a reality that is too painful or threatening to handle. We are not talking about mere skepticism or doubt here; we are talking about a complete and utter refusal to face the facts.

Now, why would anyone do this? Well, denial is not necessarily bad per se. In fact, it can be helpful in the short term. Imagine receiving devastating news, such as a serious medical diagnosis. An initial period of denial can be a sort of “emotional cushion” that gives you time to adjust to a harsh new reality. But as with many defense mechanisms, the problem comes when denial is prolonged or applied in situations where facing reality is very important.

You want examples, don’t you? A classic one is the alcoholic who insists he doesn’t have a drinking problem, even though it’s affecting his health, his job and his relationships. By denying the problem, he avoids the emotional pain that would come with acknowledgment, but he also deprives himself of seeking help and improving his situation.

Another example might be someone who is in a toxic romantic relationship but refuses to admit the warning signs, such as abusive behavior or excessive control. Denial here acts as a shield, protecting the person from the emotional pain that would come with accepting that their relationship is unhealthy. But that shield also acts as a barrier preventing him or her from taking action to change the situation.

Understanding denial requires empathy and self-examination. Therapy can help you explore the roots of denial and find healthier ways to cope with painful or uncomfortable realities.


Rather than denying a reality or projecting unwanted feelings onto others, rationalization seeks to explain behavior or circumstances in a way that makes them seem more rational, logical, or socially acceptable. It is as if your Self becomes a defense attorney, creating arguments to justify something that, deep down, you know is questionable.

The danger of rationalization is that it can be incredibly persuasive. Often, the explanations we create sound so reasonable that we even believe them ourselves. And therein lies the risk: while rationalization can alleviate guilt, anxiety or inner conflict, it can also lead us away from a more honest and direct understanding of ourselves and our actions.

For example, imagine someone spends all weekend watching TV shows instead of studying for an important exam and then fails. He might rationalize his behavior by saying, “Well, I needed a break, the professor doesn’t teach well anyway, and a single exam doesn’t determine my worth.” While each of these points might have a grain of truth to them, taken together they act as a smokescreen that avoids facing the more direct reality: procrastination and lack of preparation.

Another classic case is that of the “sour grapes” in Aesop’s fable of “The Fox and the Grapes“. The fox cannot reach some grapes that are too high on the vine, and then rationalizes her failure by saying that the grapes were probably sour anyway. This is an attempt to make her failure seem less painful by changing the narrative.

It’s natural to want to avoid emotional pain or conflict, and rationalization often provides a quick way out. But if this defense mechanism becomes a recurring pattern, it can be an obstacle to personal growth and authenticity. In therapy, the goal would be to identify where and when you are rationalizing, and then explore the underlying emotions and beliefs that are driving this behavior. After all, knowing yourself is the first step to any kind of meaningful change.

Reactive Formation

This mechanism involves transforming an unacceptable impulse, desire or feeling into its opposite, and often in an exaggerated way.

If repression is like putting something in a drawer and locking it, reactive formation is like putting that same object in a display case and surrounding it with bright lights for all to see. But what is exhibited is just the opposite of what you really want to hide.

Let’s go to the examples, which are always enlightening. Imagine a person who feels a strong resentment towards his boss. Instead of openly expressing this feeling or even admitting it to himself, he acts with extreme kindness and deference toward his boss. He might bring him coffee every morning or constantly praise his leadership skills. On the surface, he looks like the employee of the month, but in reality he is using reactive training to manage feelings he finds unacceptable.

Another common example might be someone who has homosexual feelings but finds them unacceptable because of his or her upbringing or personal beliefs. This person might become a staunch advocate of anti-LGBTQ policies as a way to“prove” their own heterosexuality, both to themselves and to others.

As you can see, reactive formation can be quite an elaborate and often deceptive defense mechanism. From the outside, it can be difficult to see what is really going on. And from the inside, the person may come to believe his or her own performance. Therapy can be helpful in unraveling these behaviors, allowing you to more healthfully confront and manage the impulses or feelings you are trying to avoid.

If you pay attention, you may find that this mechanism bears some resemblance to denial. The difference is that in reactive training, instead of simply living with our backs turned to a problem or situation, we try to get as far away from it as possible.


Introjection is one of those defense mechanisms that may seem a bit abstract at first, but is incredibly revealing once you understand it. Basically, introjection involves internalizing qualities, attitudes, or norms from important external figures, such as parents, mentors, or even social groups. It’s as if you take a piece of the outside world and embed it into your own sense of self to manage anxiety, conflict or insecurity.

This mechanism is especially common in childhood. Children often introject qualities from their parents as a way to feel more secure and connected. But make no mistake, adults do it too. For example, someone growing up in an environment where autonomy is highly valued might introject that norm to the point of feeling very uncomfortable asking for help, even when necessary. Or think of the classic case of“imposter syndrome,” where someone introjects such high standards that they feel they are never good enough.

Introjecting is not inherently bad. In fact, it can be a valuable way to learn and adapt. However, when the introjected qualities or standards are harmful or unrealistic, it can lead to emotional and behavioral problems. If you are always trying to live up to internal expectations that are impossible to achieve, you are setting yourself up for constant failure and disappointment.

Another example might be someone who grew up with a very critical parent and has introjected that critical voice. Even though the parent is no longer physically present, that internal critical voice persists, leading the person to be excessively hard on themselves in various situations.

In therapy, one of the goals would be to identify what we have introjected and how that is affecting our life and well-being. From there, you can work on dismantling or modifying those internalizations so that they are more in line with your authentic self and your own needs and desires. It’s a fascinating journey of self-discovery, and it’s always rewarding when someone manages to replace a harmful introjection with something more positive and beneficial.


This is the Self’s tactic of separating a thought from the emotion or anxiety associated with it, almost like dissociating the emotional content from the cognitive content.

This mechanism can be especially useful in extremely stressful situations. For example, medical professionals often have to use a form of isolation to separate their emotions from the immediate task at hand, such as performing a complicated surgery. In these types of situations, isolation is vital; allowing emotions to interfere could have serious consequences.

But like all defense mechanisms, isolation has its dark side. Used to excess or in contexts where coping with emotions is key, it can lead to problems. Imagine going through a painful breakup but forcing yourself to think of it as simply an event that“had to happen” or“it’s what’s best for both of you,” eliminating any pain or sadness you feel. It might seem like you’re adjusting well, but in reality, you’re avoiding processing important emotions that will eventually have to come to the surface.

Another example might be someone who experiences a traumatic event and is able to talk about it with complete emotional detachment, as if they were recounting a grocery list. This emotional detachment can be disconcerting to others and, more importantly, can be an obstacle to long-term emotional processing and healing.

You see, isolation is a double-edged sword. It can be a lifesaver in situations where objectivity is critical, but an obstacle when it prevents us from facing and processing our emotions. In therapy, the work would be to identify when and how you are using isolation, and find healthier and more comprehensive ways to manage stress and emotional pain.


who hasn’t daydreamed about winning the lottery, becoming a rock star, or going on an epic adventure? Fantasy as a defense mechanism is basically a form of escapism, a way to get away from the less pleasant realities of life and retreat into an imaginary world where anything is possible, and usually, everything is much better.

Now, daydreaming from time to time is completely normal and even healthy. It is a form of mental rest and can be a source of creativity and inspiration. The problem arises when daydreaming becomes a kind of constant refuge from facing real problems, responsibilities or uncomfortable emotions. If you are always imagining that you are the hero who saves the day instead of facing the fact that you are having problems at work or in a relationship, you may be using fantasy as a defense mechanism.

For example, a student who is not doing well in school might sink into fantasies where he or she is a misunderstood genius or a star athlete, rather than addressing the issues that are affecting his or her academic performance. Or someone in an unsatisfying relationship might lose themselves in romantic fantasies with a fictional soul mate instead of addressing the problems in their current relationship.

Fantasy becomes problematic when it displaces action and commitment in the real world. It’s as if you’re looking at life through a window instead of going out and living it. In that case, therapy can help you realize how and why you are using fantasy as a defense mechanism. The goal is not to eliminate the ability to dream or imagine, but to help you use that creative energy in a way that enriches your real life rather than replaces it.


When life gets complicated or stressful, there is a tendency to regress to earlier stages of development where things were, or at least seemed, simpler. I don’t mean going into diapers and pacifiers, although that would be taking regression to the extreme, but more subtle behaviors and attitudes that correspond to earlier phases of your life.

For example, an adult going through a stressful time at work might start biting his or her nails, a habit he or she had outgrown years ago. Or perhaps someone facing a significant life change, such as a divorce or the loss of a loved one, might start sleeping with a stuffed animal or blanket from childhood. Emotionally, you might notice someone becoming more needy and seeking comfort in ways that are typically associated with childhood, such as wanting to be hugged or given affection in more visible ways.

Regression becomes a problem when these behaviors interfere with the ability to effectively handle the responsibilities and challenges of adult life. Imagine that you are so stressed that you start skipping work to stay home watching cartoons all day; that would be a sign that regression is affecting your functioning.

In therapy, the goal would be to identify the triggers for this regression and find more adaptive ways to manage the stress or anxiety. Sometimes, that might involve developing new coping skills. Other times, it might involve exploring unresolved issues from those earlier stages of life that might be contributing to this desire to“regress” in time.

The interesting thing here is that these mechanisms are not inherently bad. In many cases, they are adaptive and necessary for mental health. But they become problematic when they are overused or used inappropriately, which can lead to relationship problems, self-deception and, in extreme cases, psychological disorders. In psychotherapy, part of the work is to help people recognize and understand their defense mechanisms, so they can find healthier ways to manage stress and anxiety.

So what can we learn from all this? First, that these mechanisms are there for a reason and have a purpose. Second, that self-awareness is key. By understanding what mechanisms you are using, you can begin to address the underlying concerns in a more direct and healthy way.
