Let’s start with what a defense mechanism is…

A defense mechanism describes a way your mind attempts to protect you from anxiety, guilt, shame, the fear of all three of those things, and/or any otherwise unwanted psychological thoughts or experiences.

It’s important to keep in mind that defense mechanisms are largely “unconscious.” This means you are not typically aware that you are using them. Sometimes you aren’t even aware of the psychological distress that is motivating you to use them in the first place.

Psychiatrists and psychologists classify defense mechanisms in several ways. Below I share some of those categories with you. Separately, I share with you a list of many defense mechanisms and how they can show up in your romantic relationships.

Four Common Categories of Defense Mechanisms

  1. Mature
  2. Neurotic
  3. Immature
  4. Pathological

Mature Defense Mechanisms

These are considered healthier, more functional ways of dealing with psychological distress. When these are used, it generally means that the person has a fairly conscious grasp on what is realistically going on around them. Mature defenses are considered a helpful way of dealing with uncomfortable thoughts. They are most socially acceptable and often considered constructive ways of dealing with pain and suffering.

Neurotic Defense Mechanisms

These are considered less functional than mature mechanisms. Neurotic defenses describe ways people manage ongoing, consistent, pervasive psychological stress. Often, they help in the short-term, but lead to long-term problems above and beyond the original anxiety.

Immature Defense Mechanisms

These are less healthy and less functional than mature and neurotic defenses. They tend to be more present in adults than children. Immature defenses pose significant threats to people’s most important relationships. These are usually present in a number of significant mental health diagnoses, including disorders of the personality. However, they are quite commonly used.

Pathological Defense Mechanisms

Just as the name suggests, these defense mechanisms suggest severe mental dysfunction. Pathological defense mechanisms involve a distortion of reality to the degree that it can’t or doesn’t make sense to other people. Interpersonal relationships are extremely difficult to manage and overall functioning in the world is severely compromised.

30 Defense Mechanisms, Their Meanings, & How They Show Up in Romantic Relationships

Please note: I’m purposefully not categorizing the defense mechanisms the way theory does.

Why?

One, because I’m not sure I agree with them all.

Two, because some can fit into multiple categories at the same time.

Three, because I believe in empowering you to uniquely decide for yourself where you think something fits.

And four, because things change. What feels like it may fit in one category today, may fit into another category next month.

If you choose to read on, please keep in mind these Very Important Points:

  1. This list below is fairly comprehensive of the defense mechanisms themselves.
  2. The definitions are purposefully and overly simplified to make it easier to understand.
  3. In order for it to qualify as a true defense mechanism, the examples should be considered behaviors that happen consistently or chronically; not just once in a while.
  4. Many of these examples are things that simply “just happen” in relationships and are not otherwise considered as possible defense mechanisms. In fact, some of them are actually helpful in relationships.
  5. None of the examples are explanations for what is going on for you or your partner. They are possibilities. There can be and often are other explanations for why these examples occur.
  6. REMEMBER, defense mechanisms mostly operate unconsciously, which means outside of our awareness. You won’t read these and necessarily think, “I do that.” Nor does it mean that your partner does any of this “on purpose.” I can’t stress this point enough.

Now that you’re ready, here they are, in alphabetical order:

1. Acting Out

intense behaviors or expressions, with no filter or regard for how it makes other people feel, due to an inability to express oneself in a healthier way

  • Yelling at your partner alone or in front of other people (e.g. family, friends, or in any social setting)
  • Threatening or hurting your partner (physically, psychologically, economically, etc.)
  • Interrupting your partner and refusing to listen to what they have to say

2. Altruism

Engaging in constructive behaviors that seem to help, provide some sort of positive offering, and aim to please or satisfy as a means to offset ways the altruistic partner is unsatisfied

  • Not talking or responding when your partner is speaking to you
  • Spending a lot of time by yourself to reduce the chances of having to deeply connect

In Closing

If you’re wondering whether or not any of these defense mechanisms are present for you or in your relationships, please consider reaching out to an individual or couple’s therapist who can help you explore them for yourself.

Remember, these definitions were severely edited to relay them in as easy to understand of a way as possible. The examples may or may not be indicative of an ongoing defense mechanism used by you or your partner. Many defense mechanisms are healthy and functional. The ultimate goal is to give you some information to help you better understand you and yourself in relationships; regardless of any labels.
