Defence Mechanisms in Everyday Life: How We Unknowingly Protect Ourselves from Discomfort

We all like to think we see the world as it is; rationally, clearly, and without distortion. But in reality, our minds are constantly working behind the scenes, filtering, reshaping, and even blocking out certain thoughts and emotions. These unconscious processes, known as defence mechanisms, help us manage discomfort, but they can also prevent us from growing and keep us stuck in unhelpful patterns.

By understanding how these defences operate in our everyday lives, we can begin to work with them rather than be controlled by them.

Sometimes what we think protects us can just keep others away

Some Common Defence Mechanisms in Everyday Life

1. Denial – “This isn’t as bad as you make it out to be.”

Denial is the refusal to accept reality because it feels too painful or overwhelming. It’s the friend who insists their toxic relationship is fine, the employee who ignores warning signs of burnout, or the person who avoids thinking about a serious health issue.

🔹 What to learn from it: Denial can provide short-term relief from anxiety, but lasting change requires acknowledging difficult truths. If you notice yourself avoiding certain facts, ask: “What might I be protecting myself from?”

2. Projection – “It’s not me, it’s them.”

Projection occurs when we attribute our own uncomfortable thoughts, feelings, or motivations to someone else. A person who struggles with anger might see others as aggressive, or someone who feels insecure may accuse others of being judgmental.

🔹 What to learn from it: When you find yourself strongly reacting to someone, consider: “Is this about them, or am I seeing something I don’t want to face in myself?”

3. Rationalisation – “There’s a perfectly good reason for this.”

Rationalisation is when we justify behaviours or emotions with seemingly logical explanations, even when they don’t fully hold up. For example, someone who wasn’t selected for a promotion might convince themselves they never really wanted the job anyway. This helps protect us from pain and sadness by justifying a lack of response.

🔹 What to learn from it: Pay attention to the stories you tell yourself. Are they true, or are they a way to avoid uncomfortable emotions?

4. Displacement – “Taking it out on the wrong target.”

Ever snapped at a loved one after a stressful day at work? That’s displacement - redirecting negative emotions from their true source and directing them towards a safer outlet for our aggression. Instead of confronting an intimidating boss, for example, we might take our frustration out on a partner, team member or friend.

🔹 What to learn from it: If your reaction to a situation feels bigger than it should be, ask: “Am I really upset about this, or is there something else upsetting me?”

5. Repression – “Burying it deep.”

Repression happens when we push distressing thoughts or memories out of awareness. Unlike consciously deciding not to think about something, repression occurs unconsciously. While this can protect us in the short term, unresolved issues often resurface in unexpected ways - through anxiety, dreams, or physical symptoms; before potentially becoming unavoidable and eventually feeling insurmountable.

🔹 What to learn from it: If certain situations consistently trigger strong emotions, or cause you to avoid an issue, it may be worth exploring whether something is being repressed.

6. Reaction Formation – “Doing the opposite.”

This occurs when we behave in a way that is the opposite of how we truly feel. Someone who has strong feelings of attraction that they find unacceptable or unfaithful might act cold or hostile towards that person. A person raised to see anger as unacceptable might become excessively accommodating and agreeable instead, endlessly bottling up their true feelings until the pressure becomes too much.

🔹 What to learn from it: If you notice an extreme reaction to act or behave in a certain way, consider: “Is this to mask something deeper I find unnacceptable?”

Why This Awareness Matters

Defence mechanisms are not inherently bad - they serve a protective function and provide relief to manage or survive stressful environments and traumatic events. However, when they become rigid, ingrained and inescapable, they can prevent us from growing, processing our emotions, and developing healthier ways of coping or relating to others.

By recognising these patterns in ourselves, we gain the ability to step back, reflect, and make more conscious choices. When we stop defending against discomfort and start engaging with it, we open the door to real change, deeper self-awareness, and more authentic relationships.
