The Hidden Wisdom of Defense Mechanisms
Maeve Boon, Advanced Clinical Fellow
Have you ever caught yourself thinking, Why did I react that way? or Why do I keep doing this even when I know it's not helping? If so, you've already started asking questions about defense mechanisms.
In psychology, a defense mechanism is an automatic, mostly unconscious strategy the mind uses to protect us from fear, emotional pain, or realities that feel difficult to face.
Importantly, defense mechanisms aren't something we need to "get rid of." Psychologist Nancy McWilliams, whose work has been deeply influential in contemporary psychodynamic therapy, describes defenses as serving an important protective function. In other words, our minds develop them for a reason. They help us navigate experiences that once felt too painful, overwhelming, or threatening to face directly.
Therapy isn't about stripping away our defenses. It's about getting curious about them and asking questions like: what are they trying to protect us from, when did they become necessary, and are they still helping us today?
A coping strategy that once helped us survive a difficult chapter of our lives may not be the strategy that helps us thrive today. As our lives change, the ways we cope often need to adapt as well.
Defense mechanisms become problematic not because they exist, but because they can become rigid. When we rely on the same defense in every situation, it can begin to limit our ability to respond flexibly or address what's really asking for our attention.
Some expressions of defense mechanisms are described as "immature" defenses. This doesn't mean that the person using them is immature. Rather, it refers to coping strategies that tend to be less adaptive when they become our primary way of responding to stress, or are used in situations where they contextually don’t make sense.
Some examples include:
Extreme Denial: Having difficulty acknowledging a reality that feels too painful or threatening to accept.
Projection: Attributing feelings or impulses to someone else that may be difficult for us to recognize in ourselves.
Idealization and devaluation: Seeing someone or something as entirely wonderful or entirely terrible, with little room for the complexity in between.
These defenses aren't inherently "bad." In fact, they often protect us from becoming emotionally overwhelmed. Denial, for example, can create enough psychological distance for us to cope with devastating news one step at a time. The difficulty arises when a defense becomes our default response long after it has stopped serving us.
Other defenses are generally considered more "mature." That doesn't mean they're perfect. Rather, they're strategies that tend to help us tolerate difficult emotions while staying connected to reality, ourselves, and the people around us.
Examples include:
Humor: Finding something funny in a difficult situation without denying that the situation is difficult.
Suppression: Intentionally setting aside a difficult thought or feeling for the moment so we can focus on what needs our immediate attention.
Anticipation: Thinking ahead about a stressful situation and preparing ourselves for it.
Sublimation: Channeling difficult emotions or impulses into constructive outlets, such as exercise, art, writing, or other forms of creativity.
Of course, the distinction between helpful and unhelpful defenses isn't always clear-cut. A defense that works well in one situation may not work as well in another. Humor might help us get through an incredibly stressful week, but if we use it to sidestep every vulnerable conversation, it may become harder to connect with the people around us. Likewise, denial can become problematic when it consistently obstructs our view of reality. Yet in the face of overwhelming circumstances, a brief period of denial can sometimes soften the initial impact, giving us the psychological space to begin coping with what has happened.
In therapy, we don't usually try to force defenses away. Instead, we become curious about them.
Maybe you notice that you always change the subject when conflict comes up. Or you automatically tell yourself, It's not a big deal, even when you're deeply hurt. Maybe you become intensely self-critical after making a mistake or convince yourself that you don't need anything from anyone.
Over time, therapy can help us develop greater emotional awareness, become more comfortable experiencing difficult feelings, and recognize the patterns in how we respond to stress. As we better understand our defenses, we gain more flexibility. With greater flexibility and awareness comes more choice.
Learning about defense mechanisms can help us approach ourselves with greater compassion. Instead of asking, What's wrong with me? we can begin asking, What was my mind trying to protect me from?
Often, the very patterns we criticize in ourselves were once creative ways of surviving difficult experiences. That doesn't necessarily mean they're the strategies we need today, but recognizing the purpose they once served can make change feel less like a battle against ourselves and more like an act of understanding.
Therapy isn't about declaring our defenses "good" or "bad." It's about understanding them, appreciating the role they've played in our lives, and developing the flexibility to choose new ways of responding when they're no longer serving us.
